10” Low Profile
Amplified Subwoofer
BASS1200 Amplified Subwoofer User’s Manual - page 2
Introduction
The BASS1200 is a low-profile
amplified subwoofer. Low enough to
easily fit below the seat of your car,
this system offers you a quick and
easy way to add a high-powered
subwoofer system to your audio
system.
The integrated amplifier in the
BASS1200 features a low pass
crossover and a subsonic filter, as well
as a control for adjusting the input
sensitivity from 0.2V to 6V.
Both high level (speaker level) and low
level (RCA type) inputs are present,
making this a universal solution for use
with any head unit or other input
source.
For further flexibility in the use of a
subwoofer, a variable bass boost
control has been included. You can
control the subwoofer level with the
remote level control module.

What should I do if the POWER STATUS
LED turns RED?
If you observe that the POWER STATUS
LED IS RED, please check the system
carefully to determine what has caused
the protection circuit to engage.
To reset the amplified subwoofer when
it is in PROTECT mode, turn the power
off to the system (usually by turning off
the head unit or other signal source
which feeds the amplifier) and then turn
it on again.
If the internal amplifier has shut down
due to thermal overload, you should first
allow it to cool down before restarting.
If the shut down was due to either an
input overload or a short circuit, be sure
to correct these conditions before
attempting to power up the subwoofer
again.
The built-in amplifier incorporates
special protection circuitry which will
disable the amplifier if any of the
following should occur:
• Input overload
• Short circuit
• Extremely high temperatures
If any of these conditions is detected,
the amplifier will go into a selfpreservation mode, and the PROTECT
LED on the control panel will glow in
RED color.

Installation precautions
Before you drill or cut any holes,
investigate your car's layout very
carefully. Take special care when you
work near the gas tank, fuel lines,
hydraulic lines and electrical wiring.
Never operate the subwoofer when it
is unmounted. Attach all audio system
components securely within the
amplifier to prevent damage, especially
in an accident.
Do not mount this product so that wire
connections are unprotected, in a
pinched condition, in contact with any
metal surfaces in your vehicle, or likely
to be damaged by nearby objects.
Before making or breaking power
connections in your system,
disconnect the vehicle battery. Confirm
that your head unit or other equipment
is turned off while connecting the input
jacks and speaker terminals.
If you need to replace the power fuse,
replace it only with a fuse identical to
that supplied with the product. Using
a fuse of a different type or rating may
result in damage to your audio system
or your amplifier which is not covered
by the manufacturer's warranty.
Fuses
Power fuses protect both the amplifier
and the electrical system of your car
from fault conditions. If you must
replace a fuse in your BASS1200
powered subwoofer, use a fuse of
exactly the same type and rating. Using
a different type or rating of fuse may
result in damage to your amp or vehicle
or cause a fire.
