The Outside
1) Inputs: The inputs of MEGA BASS use a balanced input circuit to help minimize feed back. They are also
designed to handle very high signal voltage up to 15 volts.
2)
Outputs: These RCA connectors should be connected to the next component after MEGA BASS, such as a
crossover, equalizer or amplifier. Just remember that MEGA BASS should be in line before a crossover.
3) Dash
Input Contrai: This allows you to connect MEGA BASS to the remote control knob. You can mount the
knob anywhere you want, although somewhere in the font of the vehicle ìs most common. (Remote Must Be Connected
For The Unit Operate Correctly)
4)
Power Connection: This connector allows you to connect the Ground and Remote TURN-ON signals to
MEGA BASS. Connect ali of the wires to their appropriate locations in a
welllit area and then plug it into MEGA BASS
where ever you decided to mount it in your vehicle.
5)
Bass Controls: These 2 knobs control the bass functions fo MEGA BASS.
The SWEEP knob allows you to pick the center frequency that you want MEGA BASS's restoration circuit to maximize.
The WlDE knob adjust how wide of a frequency range MEGA BASS will effect.
6) Power: When you have connected ali of your wires correctly the POWER light should illuminate. If it does not
then you need to check your wires. .

The Inside
1) Input Grounding: Far most systems you can leave this jumper set in the BALANCED position. In some
systems, the source unit may look far a ground through the RCA connectors. In that event, you should go ahead and
" change the jumpers to the UNBALANCED position. 4\
2) Ground Isolation Jumpers: Occasionally alternator whine may appear in a system because the source unit
J and amplifier may use different grounding. To help in this situation, we have provided alternative grounding connections.
Make sure your system is turned OFF bare you move these jumpers.
3)
Bass Output Control Jumpers: Not ali systems are designed the same, some systerns are designed strictly
far SPL while other are far average use. MEGA BASS's maximizer circuit can either increase or decrease the signal
voltage of the bass restoration circuit. Depending upon your system , you may
wantto change these jumpers to a higher or
lower setting to maximize your bass output and protect your speakers. In most systems the factory setting will suit you
fine. We recommend that you try the factory setting before any other.

Placement and Mounting
INSTALLING MEGA BASS
Placement and Mounting
Placement: MEGA BASS needs to be installed in the signal path as close to your source unit as possible, but
definitely before any crossover circuit. Although MEGA BASS is close to the source unit's signal, the chassis is usually
mounted in the rear of the vehicle as close to the amplifiers as possible. We recommend connecting the MB1 to the
EQ7000PXi SUB OUT and have it drive the bass amplifier.
Mounting: Once you have selected a permanent mounting location, position the unit and mark the appropriate
mounting holes with a pen or pencil. Before doing anything else, make sure you are not about to drill a hole in a gas tank
or pierce existing wires orcables. Now drill a small pilot hole and mount the unit.
Electrical Connections
WARNING: Failure to disconnect the negative terminai of your battery prior to installation may result in
severe
shock or damage of you system components. .
Remote In: Connect a 22 to 18 gauge wire from the head-unit's remote turn-on to the REMOTE-IN connector of
MEGABASS.
Positive(+12v)
Connection: Insert and 18 gauge or larger wire into the connector label'edPOWER on the
connector of MEGA BASS. Connect it to a good constant source of 12 volts, fused at 1-amp.
Ground Connection: Use the same gauge wire you did for the 12v connector on MEGA BASS's NEGATIVE
terminai of the battery, a ground bus, or a verified ground location. The factory head unit ground is not a good ground.
When ali connection are complete you may reconnect the negative battery terminai it's originai state.

Bass Control CenterAdjustments
ADJUSTING THE BASS CONTROL CENTER
The bass response in a system is affected by four factors:
1. The acoustics of the vehicle
2. The locations of the speakers
3. The music on the tape, CO or source unit
4. The speakers and or speaker enclosures
..
Because of the variations in the record ing process we developed
MEGA BASS to help restore any low frequencies lost
during the recording process or from source units, however, the acoustics of various environments are different. With this
in mind our engineers developed this fantastic system.
The SWEEP control allows you to select a center frequency between 27 and 63Hz. The WIOE control then allows
you to control the shape of the filter centered around the SWEEP frequency.
SETTING THE BASS OUTPUT CONTROL
MEGA BASS is the most powerful bass component on the market. It is able to leap to dramatically enhance any
audio system to audiophile status or preference. MEGA BASS is equipped with several different bass output selections. If
you should need to change the settings, please use the chart below for guidance. Before making any changes try listening
to the factor settings...they may be just what your looking for.
RECOMMENDED SETTINGS
Sellinq Amplifier Input Voltage Minimum Speaker Size
2.5 Volt 3 Volts or less 8"
5 Volt . 5 Volts or less 10"
7.5 Volt 7.5 Volts or less 12"
10 Volt 10 Volts or less Some Kind of Beast
DPF D.C. Protection Filter
Many car audio systems truly push the Iimits of their subwoofer, without really knowing it. Tuned
enclosures affect the roll-off of many speakers, yet lots of source materiaI forces the speakers to play lower
than expected. The net result i s wasted amplifier power and damaged speakers. MEGA BASS's DPF
Overdrive is a programmable subsonic filter. It allows you to only let the speaker play as low as it should be
played. Because every system is different, we allow you to change the DPF roll-off frequency to whatever you
choose.
