2/4-Channel Amplier (Mini)
Thank you for your purchase of Cycle Sounds® Bagger Audio™ 2/4-Channel Mini
Motorcycle Amplier. Cycle Sounds 2/4-Channel Amplier uses a 4 layer PCB to
ensure low noise and to ensure that EMI and RFI emissions on Class-D ampliers
are kept to a minimum so that FM broadcasts are not interfered with.
Before you begin, please read instructions carefully and thoroughly and make
note of the following guidelines:
Take proper precautions to protect your paint in the areas that you will be
working near.
Prior to removal of any parts, conrm that you have all tools necessary to
complete the installation. If you get to a point where you are unsure of how to
continue, please review the instructions again and conrm the steps that you
have already completed.
If additional assistance is needed please contact Cycle Sounds at
1-866-427-2346 (toll free) or 816-525-2628.
Installation Instructions
Location:
Choose a suitable location in the vehicle which will allow sucient airow over
the amplier. The preferred mounting direction is with the heat sink ns in a
vertical direction. However we do recognize that this is not always possible. For
motorcycles inside the fairing (top of radio) or inside of a saddlebag is generally
suitable.
Mounting the amplier:
This amplier can be mounted in a couple of dierent ways depending on
your application. Generally, using Velcro on the underside of the amp inside of
a motorcycle fairing is ne. Make sure the amp is secure however you choose
to mount it. If you are putting the amplier into a saddlebag or other “vertical”

mounted location it is best to use the mounting tabs.
Fusing of amplier:
Almost every amplier is OVER FUSED, period! Over fusing is just a silly thing to
do as it aords ZERO protection and only results in printed circuit boards being
burnt together with a bunch of expensive silicon. The formula is quite simple. For
class A/B ampliers add up the total wattage of all channels into the impedance
into which they are driven. Divide this number by 18 and use the closest value
fuse. Example a 100w x 4 at 4 ohm amplier is 400w total. Divide by 18 = 22.22 so
use a 25A fuse. A 1500w amplier requires a 90A fuse. We prefer to make up a nal
fuse value by using several lower amperage fuses in parallel. This results in better
thermal eciency as the current ow is spread over several pieces of metal.
We advocate strongly to under fuse and if you nd under hard drive that the fuses
occasionally open up then it is less pain on your wallet to replace some fuses with
a slightly higher value.
The higher the impedance of the speaker (>4 ohm) the better the sound quality.
These ampliers are NOT SPL tools, they are for listening to good music at
reasonable levels - protect your ears!
Connecting the Amplier:
Once the amplier has been mounted in the desired location the electrical
connections can be made. The rst step is to connect the speakers. Using the
appropriate size of wire (we recommend a min of #14) connect the speakers as
shown in the later diagrams. The next step is to connect the line inputs using
high quality RCA-RCA cables. The source to which the line inputs are connected
depends on the particular installation. Refer to later diagrams or consult a
qualied audio technician.
The next step is to connect the power inputs. The rst is the ground wire. This
wire is connected to the (-) connection on the 3 terminal power connector. Using
#8 wire or larger(#4 max) insert one end into the connector’s GROUND terminal
after stripping o about 19mm (0.75”) of insulation. Trim the wire to a maximum
length of 1 meter (39”). This ground wire (normally BLACK) is then crimped (and
preferably soldered) into an appropriate size ring lug. Then simply run the power
and ground connections to the battery and connect them to (+/-) respectively.
(Optional) Next is the remote turn on wire. This is normally connected to the
remote output of the head unit on a factory motorcycle radio or can be hooked
up to 12vdc switched ignition.
Last is the +12volt connection. Using #8 (#4 max)or larger, strip the wire to 19mm
(0.75”) and insert in to the hole marked BATT (+) on the power connector. Run
the cable (away from all audio cables) to the location of the bike’s battery. At
the battery location install the fuse holder no further away from the battery (+)
terminal than 300mm (12”). Insert this end of the +12volt power cable into the

fuse holder. Making sure that the fuse is removed, connect the other end of the
fuse holder to the battery’s (+) terminal using appropriate high quality battery
connectors. Insert the supplied fuse. DO NOT OVERFUSE as this can be a re
hazard.
The power connector on our amplier can accommodate wire with a copper
diameter of up to 7mm (0.275”).
This amplier utilizes a fully regulated power supply so output power is
independent of the battery voltage (12v-14.4v). It also features a variable subsonic
crossover, a 24dB/octave Linkwitz-Riley Low Pass crossover, a 40Hz low frequency
equalizer provides up to 12dB of boost and the level control allows the amplier
to accept signals up to 9v RMS in unbalanced mode or 18v RMS in balanced
mode.
The remote level control module has a two color LED, green shows power and
when it turns red indicates that the amplier is clipping.
Channels 1+2 allow the user to choose between a FLAT response, HIGH PASS or
LOW PASS. The level control allows the amplier to accept signals up to 9v RMS
in unbalanced mode or 18v RMS in balanced mode. Channels 3+4 mirror the
features of channels 1+2. The amplier channel pairs are of course bridgeable so
can function as a two channel amplier rated at 140w/ch at 8 ohms or 200w/ch at
4 ohms.
Both ampliers feature the usual protection circuits such as DC, short circuit and
thermal. Owing to the small size of these ampliers, it is important to keep them
as well ventilated as possible. There is no restriction to mounting them vertically
or horizontally.

Troubleshooting
Amplier will not power up:
Check for battery power at amplier’s power terminals. Check for voltage at
REMOTE terminal must be greater than 3 volts. Make sure protection LED is o. If
it is on, turn the amplier o for 5 seconds and then power up again. If LED comes
on, again refer to LED notes below.
Amplier gets hot:
The amplier is OK if you can keep your hand on the chassis with no discomfort. If
it seems to get very hot make sure the speaker impedance is correct.
High “hiss” heard in speakers:
Remove the RCA plugs from the amplier. If hiss disappears the problem is the
source. Set the amplier’s level control as insensitive as possible. It is best to drive
the highest signal level from the head unit as possible. The higher this signal level
the better the subjective S/N ratio is.
Protection LEDs ash:
Remove speaker connections from amplier. Turn amplier o for 5 seconds. Turn
on again, if LED is o the problem is with the speakers. Check for shorts on the
cables and on each speaker. If the LED comes on, the amplier is faulty.
Engine noise:
Check spark plug wires. Check that RCA cables run away from power cables. Use
only high quality RCA cables.
Alternator whine:
Check grounding of head unit. Run head unit’s +12 connections directly to the
battery +12v terminal. Make sure all ground connections are rust free. Check that
RCA cable grounds are not shorted to the chassis in their run from the amplier to
the head unit. Disconnect the RCA cables from the amplier. If whine disappears
the problem is upstream.
Sound is distorted:
Check RCA cables for shorts. Check speakers and cables. Check amp level is
matched to that of head unit.
