6. Low Pass Filter (LPF) control
– This knob controls the highest frequency range that is sent to the
subwoofer(s). The range is adjustable, from 40 to 180 Hz with a third order slope of 18 dB per octave.
The value that this should be set to changes depending on the subwoofer(s), enclosure and vehicle used.
This can be set by starting with the knob position fully clockwise, then turning the knob anti clockwise
very slowly until the best result is heard. This may take some time to get exactly right. It is advisable to
play music of the genre that will most commonly be listened to as this is set. It is also advisable to use
different tracks when configuring the LPF.
When set correctly, the subwoofer is able to work more efficiently, and the upper frequency range
reproduced is configured to the equipment, surroundings and user taste.
7. Phase – This knob controls the continuously adjustable signal phase lag control of the subwoofers
from 0 to 180 degrees. To find the optimum setting, it is ideal to have one person slowly turning the
knob clockwise (from 0 degrees) fully round to 180 degrees, while the listener is sitting in the vehicle.
The knob should be lest in the optimum position (listen out for smooth bass, bass response and power).
When set correctly, the subwoofer(s) in the vehicle will be adjusted to suit the vehicle and other speakers
in the vehicle.
8. Subsonic Filter – The subsonic filter is the opposite of the LPF; the knob controls the lowest
frequency range that is sent to the subwoofer(s) (effectively a high pass filter). When the knob is turned
fully anti-clockwise, the filter is off. To switch the subsonic filter on, simply turn this knob clockwise,
from which point, the range is adjustable from 5 to 50 Hz with a third order slope of 18 dB per octave.
The value that this should be set to changes depending on the subwoofer(s), enclosure and vehicle used.
This can be set by starting with the knob position fully anti-clockwise, then turning the knob clockwise
very slowly until the best result is heard. This may take some time to get exactly right. It is advisable to
play music of the genre that will most commonly be listened to, as this is set. It is also advisable to use
different tracks when configuring the subsonic filter. For some tastes and situations, the subsonic filter
may not need to be switched on at all.
When set correctly, the subwoofer is able to work more efficiently, and the lower frequency range
reproduced is configured to the equipment, surroundings and user taste.
9. Bass Boost – This knob controls a boost of the bass frequencies at and around 45 Hz. There is no
“bass boost” when the knob is turned fully anti-clockwise. Turning the knob clockwise from this position
boosts the frequencies around the region of 45 Hz by up to 12 dB.
10. Speaker Connections - These are screw terminals for attaching the subwoofer speaker cables.
Undo the screw head enough to slot a stripped end of subwoofer speaker cable into the terminal, and
then tighten the screw. Please see wiring diagrams in the “Installation” section for how to connect
subwoofer speakers to the amplifier. To operate the amplifier in bridge mode, follow the lines printed
next to the terminals on the side of the amplifier. By doing this you connect “CH 1” “+” to “CH 2” “-”.
The minimum load impedance at bridge is 2 ohm, when using both channels, the minimum load
impedance per channel is 1 ohm.
11. Power Connections – This is where all the power leads are connected to the amplifier. Particular
care must be taken when connecting, NOT to cross any of the cables.
“12v” is the positive connection from the battery. “-” is the negative or earth connection and “REM” is
the remote or ignition connection.
Mounting Instructions
Before mounting, please read the “Installation” section. The best place to mount the amplifier is
somewhere where it will not get damaged, eg. by items in the boot of the vehicle. The amplifier
dissipates heat using its heat sink; somewhere with sufficient space and air would be fine. Therefore
placing the amplifier in between items, placing items on top of it, or mounting it upside down is not
advisable.
Examples of surfaces are: the floor of the boot, fake floor of boot (MDF), side of subwoofer box, or side
of boot. Never mount the amplifier outside of the car, in the engine bay or anywhere where it has a risk
of getting wet. Normally it is best to attach the amplifier to a board, and then attach the board to the car
body. This is good practice to avoid noise problems.
Before mounting, make sure that the surface is suitable and free from any obstructions. Use the
amplifier as a template and mark where the holes are to be drilled with a pencil or pen. Drill the pilot
holes with a drill bit of diameter smaller than that of the screws.
Then place the amplifier on the surface and tighten the screws until they are holding the amplifier
securely in place.

Control Panel Functions
1. Indicators:
Power indicator - This LED will light when power, remote and earth are all connected to the amplifier. If
this LED is not on, there is a problem with one of these connections.
Protection Indicator - This LED will light if the amplifier has detected a fault and has shut down to protect
itself from permanent damage. This will be due to one of the following: excessive heat, reverse polarity,
short circuit or input overload. If this happens disconnect the amplifier and investigate the problem.
2. Remote Gain – The supplied “Remote Gain Controller” plugs into this socket. With a long run of
cable attached, the gain controller can be positioned in the front of the car so that the level of the output
can be adjusted from the front. Most source units support “fade” function, where the level of the pre-out
signal sent to the amplifier from the source unit can be altered giving exactly the same effect. However,
this provides a hard-wired solution to gain control from the position of the listener. Please see “Gain
Control” notes below. Connection is optional.
3. Audio Input – This section is labelled “Input”, and consists of two RCA phono sockets, one “R” (red)
and one “L” (white), above each other. These are for the audio input. A source unit that supplies a “line
level” (pre amp) audio output in the form of RCA phono plugs is required to connect to the input (via a
phono extension lead). A high quality shielded lead is recommended as this will help reduce the
possibility of noise entering the system.
4. Bridge In/Out – This section consists of two RCA phono sockets, and is only to be used if two of the
TL-1022 amplifiers are used together, sometimes called “strapping” or “bridging”. This can be done very
simply and easily and is explained in detail later on in this manual.
5. Gain Control - Turning the knob to the right (clockwise) will increase the volume, and to the left
(anti-clockwise) will reduce the volume. It is important to understand that the amount of gain
needed is proportional to the level of the signal coming from the source unit. For example, it
is possible for the gain knob to be at only a quarter of its maximum, but the amplifier is
actually outputting to its full potential. This could be because the source unit is supplying
slightly more power than normally expected. Please see “Installation” section for how to calibrate
the amplifier to the output of the source unit using the gain knob.
The control panels for the TL-1022 are as follows:

If you do not have sufficient experience or tools to carry out the installation, it is
imperative that you seek the assistance of someone who does, or have the
amplifier professionally installed.
Before attempting the installation of this amplifier, it is important to understand that the
TL-1022 is a substantial piece of kit; with an output of 1,500w RMS, this amplifier can
draw large currents from the vehicle battery and alternator. Depending on vehicle model,
one or more of these components may have to be replaced to enable the amplifier to
operate to its full potential.
Modifications to consider:
- Alternator. The alternator is the heart of the power supply. The diodes will fail if
the standard alternator can not supply enough current. An up-rated alternator will
not leave the amplifier starved of power. It is best to seek advice from
professionals who specialise in your make and model of vehicle to source an up-
rated alternator. Dual alternator setups are also recommended.
- Up-rated battery. A high rated van battery/specialist audio battery will enable
higher current to be drawn by the amplifier. Replacing the standard battery with an
up-rated one is highly recommended. It is best to speak to a professional who
specialises in batteries. Ideally use one suited to deep-cycle applications with a
large capacity.
- Second battery. A second battery installed as close to the amplifier’s positive
terminal as possible, with a split charging relay, ensures that there is a dedicated
battery for the amplifier. This helps protect other components on the vehicle and
keeps resistance down with the short cable run.
- Split charging relay. As mentioned above. Split charging relays usually used for
boats or caravans are recommended.
TheLoudest.com accepts no liability for any damage resulting to vehicle components when
installing or operating the amplifier. It is the sole responsibility of the user to follow these
instructions carefully and upgrade any vehicle components as required.
The TL-1102 4 AWG amplifier wiring kit is strongly recommended for use with this TL-1022
amplifier. It contains the components mentioned in the installation instructions below.
Failing this, 4 AWG cable and a 120A fuse is an absolute minimum.
Before starting the installation it is advisable to disconnect the negative terminal of
the vehicle battery. This ensures the battery will not short if the wires are accidentally
crossed during installation, and is generally good practice when making electrical changes.
Please be warned that after disconnecting the battery, your control unit (head unit) may
require a code to be entered, some car alarms may also sound. Therefore it is best to
disable the alarm before installation and enable it again after installation is complete.
Connect the power (+) cable (4 AWG red cable) directly to the positive terminal of your
vehicle battery by unscrewing the nut on the positive terminal and slipping on the power
lead connector, before replacing and tightening the nut. The TL-1102 wiring kit includes a
battery terminal block which ensures a very clean connection. There is a fuse holder and
fuse already installed on this cable if purchased as part of the TL-1102 wiring kit. If not
using the kit, you will need to install one about 60 cm from the battery, using at least a
120A fuse.
This power cable then needs to be run to where the amplifier will be mounted. Look
around the engine bay for a place to run the cable through to the inside of the vehicle.
Suitable points are usually bonnet pull grommets or air intake holes. This positive wire

Installation
Below are some basic connection configurations for subwoofers to the TL-1022. Remember that
the TL-1022 has a minimum load of 1 ohm. It is also advisable to use subwoofers which have
similar RMS power ratings, in general, a little under or over should be OK.
These diagrams show the amplifier speaker terminals connected to the subwoofer terminals.
Sometimes this is done directly, but if the subwoofer is inside an enclosure, the connections will be
made via the terminal connection block on the side of the enclosure.
The TL-1022 is a monoblock subwoofer amplifier, so there is one output channel. There are two
sets of positive and negative speaker terminals for ease of connection, they are internally bridged.
Load to amplifier: 2 ohm

OWNER’S MANUAL

Connect the remote gain controller to the amplifier. This is optional and not essential. The
plug will slot straight in to the “Remote” socket on the amplifier. The cable needs to be
sufficiently hidden out of view as it is run to the intended mounting point (usually on the under
side of the driver’s side dashboard). It is important to mount the controller in an easily
accessible location, however it must not hamper the driver in the operation of the vehicle while
driving.
Once you have checked that all the connections are good and solid, re-connect the negative
terminal of the battery. If anything goes wrong, disconnect it immediately and investigate.
The amplifier’s power LED should be lit. If not, or the protection LED is lit, please refer to the
“Troubleshooting” section.
Finally, all that is left to do is calibrate the amplifier with the source unit:
1. If using the remote gain controller, turn the knob fully clockwise to “MAX”.
2. Turn the gain knob on the amplifier all the way down
3. Play a CD or similar of music or audio that will be typically played
4. Turn the gain control on the source unit to around 70 – 80% of it’s maximum
5. Slowly increase the gain knob on the amplifier until you can hear distortion
6. Turn the gain knob on the amplifier to just before this distortion occurs (if no distortion
can be heard, this is fine!).
7. Test the system and make any equalisation changes on the source unit or the amplifier
according to taste, it may take some time to adjust all the amplifier settings to get the
most from the setup.
8. If any equalisation changes are made, repeat stages 1 to 7 until satisfied
9. Never exceed the source unit gain that you used to calibrate the system
Remember: It is possible for the amplifier gain knob to be at only a quarter of its maximum,
but the amplifier is actually outputting to its full potential. This could be because the source
unit is supplying slightly more input power than normally expected.
Bridging
Below is a diagram illustrating how two TL-1022 amplifiers can be bridged together. Please

OWNER’S MANUAL
needs to be protected from damage. Failure to protect it from damage could lead to a
vehicle fire. When you have been able to feed the cable to the inside of the car, try to
hide the cable as well as possible on its way to the amplifier (under carpet, or inside
panels).
The TL-1102 kit includes a connector already installed on the end of the power cable for
connecting it to the amplifier. Un-tighten the power (B+) terminal of the amplifier, slide
the connector in, and then tighten. If not using the TL-1102 kit, or cutting the cable to
length, strip the end of the cable and slide the end into the power terminal of the amplifier.
Competition Pro amplifiers are capable of delivering extremely high power levels.
Therefore tight, reliable and clean power connections at both ends are very important, and
ensure maximum performance.
Connect the earth (-) (or ground) cable (4 AWG black cable) to a solid, bare metal
point on the vehicle’s chassis. A common place for this is the boot catch; however any
existing substantial bolt or screw that makes contact with the car’s body near the amplifier
is sufficient. If there is no existing point, you can make one by drilling into the car’s body.
This should be done carefully as a last resort, ensuring that none of the car’s electronics or
any other component is going to be damaged. A clean connection is needed, so scraping
away the paint for the connection is required. The length of the earth cable needs to be a
short as possible, the one supplied with the TL-1102 kit will connect straight to the
negative amplifier terminal, the other end has a ring connector installed and is to be bolted
to the earthing point.
Connect the remote cable (thin blue wire) from the source unit (head unit’s) remote
output. This is called a variety of things including “remote”, “aerial”, “electric antenna”,
“REM” and “remote turn on”. To do this you will need to have access to the back of the
source unit; it will need pulled out. Please refer to the source unit’s manual to find the
right wire to use.
When the remote cable is attached to the remote output of the source unit, leave the
source unit pulled out for the moment, and run the remote cable to where the amplifier is,
down the same side of the vehicle as the power cable. As with the power cable, try to hide
it under panels and carpet. Slide the connector into the “REM” terminal and tighten.
Connect the audio signal lead (RCA phono lead) to the “line level” or “pre-out” of the
source unit. The pre-out of the source unit should be in the form of two RCA phono
sockets. Simply plug your lead into the sockets, ensuring red goes to red, and white (or
black) goes to white (or black). Then run the lead all the way to the amplifier. To
minimise noise, please ensure that the audio signal lead is run well away from the power
leads. It is normally best to run it down the opposite side of the car. If the cables
are too close, a high pitched whine can get into the system; this is engine noise.
If your source unit has no pre-outs, it is probable that it is not of sufficient quality to work
well with the amplifier; if it is giving poor quality audio then the amplifier will simply
amplify this poor quality audio. However, if a line output converter is purchased, it would
convert speaker outputs to a line level and enable you to operate the amplifier. As
mentioned, the output may not be of a great quality.
Connect the subwoofer speaker cable from your subwoofer(s) to the amplifier. Some
subwoofer configurations are illustrated on page 5, please see your subwoofer manual for
in-depth connection configurations. It is advisable to cut the subwoofer speaker cable to
size. Never connect or disconnect subwoofer(s) when the amplifier is on; you risk
permanently damaging the subwoofer(s).

Safety
Health Warning
The Competition Pro range of car audio is built for very high power handling. Listening to
music at such high powers is potentially capable of causing physical side effects such as
nausea or even permanent side effects such as hearing loss. It is therefore absolutely
essential that conservatism and a high sense of judgement are observed when in
operation.
TheLoudest.com accepts no liability for hearing disorders, nausea or other side effects
caused by this equipment.
General Safety
Playing loud music in a vehicle can hinder your sense of what is going on around you on
the road, including your ability to hear your own, and other vehicles. We recommend
listening at low or moderate levels while driving.
TheLoudest.com accepts no liability for injury, property damage or otherwise resulting
from the use or misuse of this equipment.
Do not use any chemicals when cleaning this equipment. Please use a clean dry cloth.
Do not install this unit outside the car, or anywhere where it could become damp or humid,
or where it can become exposed to the sun. It should be installed in a dry and ventilated
area inside the car.
Never connect or disconnect speakers when the amplifier is on; this can permanently
damage the speakers. Always do this when it is off.
Never open the amplifier up. Doing so would put you at risk of an electric shock. None of
the internal parts are serviceable by the user. In the case of the unit needing repair or
maintenance, please take it to a qualified professional.
For both amplifiers, the power, ground and remote connections are all installed as usual.
One amplifier is named the master. This amplifier receives signal in the form of an RCA
lead from the source unit. A single RCA lead is then used to connect the “bridge out” of
the master amplifier to the “bridge in” of the slave amplifier. All settings the user applies
to the master amplifier will automatically be sent to the slave amplifier, so there is no need
to change any settings on the slave amplifier.
When connecting the subwoofer(s), connect the negative speaker terminals of the two
amplifiers together, then the positive terminal of the master amplifier acts as a positive,
and the positive terminal of the slave amplifier acts as a negative. The minimum load
when using two TL-1022 amplifiers together in bridge is 2 ohm.
It is advisable to use two TL-1102 wiring kits for installing two TL-1022 amplifiers.
