LOW PASS FILTER
The LP filter is adjustable from 50Hz to 150Hz @12dB/Oct.
BASS BOOST
The bass boost is centered at 45Hz. Adjusting this setting will boost 45Hz up to 12dB

AUTO TURN-ON SWITCH
Placing this switch in the ON position will cause the BASS1400 to turn on as soon as you turn on the head unit in your car. If you wish to turn it on manually, leave this switch in the OFF position.
HIGH-LEVEL (Speaker level) INPUTS
If your source unit does not have RCA Pre-Amp Outputs, you can use the speaker outputs to the BASS 1400.
Use the supplied harness and connect the outputs as shown in the connection diagram in this manual.
RCA INPUTS (Low Level)
Low level inputs are the recommended way to introduce the audio signal to the subwoofer if RCA outputs are present on your head unit or other signal source(such as a sound processor).
FUSES
Fuse rating is a total of 25A, always replace the fuse with the same type and value.
POWER TERMINALS
BOSS recommends the use of high quality 8 gauge wiring. The ground should be kept under 3ft (36″).
Always scrape away any paint for the ground connection. Ground point should be clean with the correct type of bolt to secure it.
The +12V wire should be fused(25A) within 18″ of the battery, keep away from any signal and/or speaker lines to avoid noise in the system.
Remote turn-on wire should be coming from the source unit, so the amplifier turns on/off with the source.

RCA Inputs (Low Level)

RCA cables are preferred for best audio performance.
Installation lengths will vary due to sizes.
Always connect with the high-quality cables to avoid any induced noise.

NOTE: DO NOT USE/CONNECT BOTH HIGH-LEVEL AND RCA INPUTS AT THE SAME TIME

Speaker Input (High-Level)
The high-level input(s) should only be used when your receiver lacks RCA Pre- Amp Outputs.
If the RCA outputs are not present, connect the speaker outputs from the receiver to the high-level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems.

Power Input Connections

Connect the ground terminal to the closest point on the chassis of the vehicle.
Keep this ground wire to less than 3 ft. (36″) in length.
Use a high quality OFC 8 gauge wire.
Connect the remote terminal to the remote output of the head unit to “REM” using 16 gauge wire.
Connect an empty fuse holder within 18″ of the car battery, and run

Subwoofer Level Control

Mounting the subwoofer

Find a suitable location in the vehicle in which to mount the amplifier. An optional location is shown below:
Make sure there is sufficient air circulation around the intended mounting Location.
The mounting feet have multiple mounting locations.
Before drilling any holes or screws, double check you’re not about to drill into any fuel lines, brake lines, cables, etc.

Troubleshooting

If you experience operation or performance problems with this product, compare your installation with the electrical wiring diagrams on the previous pages. If problems persist, read the following troubleshooting guide which may help.
If you have any further questions, please give our Tech Department a call.

Amplifier will not power up| Check to make sure you have a good round connection Check that the remote input (turn-on has at least 9VDC Check that there is battery power on the (+)terminal Check that there is at least 12v

Check all fuse, replace if necessary

Make sure that the protection led is not illuminated. If it is lit,

Check all speaker wiring.

Low Output| Reset the level control

Check the crossover control settings.

Hissing Sound| Disconnect all RCA inputs to the power sub’s control panel. If the hiss disappears, hen plug in the component driving the amplifier and unplug its inputs. If the hiss disappears at this point ,go on

Until the faulty/noisy component is found.

It is best to set the amplifier’s input level control as low as Possible

Noise is present| Check all cables
Distorted sound| Check that the input level control is set to match the signal level of the source unit. Always try to set the input level as low as possible.

Check that all crossover frequencies are properly set.

Check for broken or damaged cable insulation on the speaker leads.

Amplifier gets very hot| Check that there is good air circulation around the amp. Adjust the input gain to properly match the source unit
Engine noise| This is usually caused by poor quality RCA cables, which can pick up radiated noise. Use only the best quality cables, and route them away from any power cables.
Engine noise (alternator whine)| Check that the RCA grounds are not shorted to the vehicle chassis. Check that the source unit is properly grounded.

Check the ground connection is clean and any paint is scraped away.
