Frequently Asked Questions - BAB10 BOSS

How do I connect the BAB10 subwoofer to my car audio system?

Use either low-level RCA inputs or high-level speaker inputs. For RCA, connect to the LOW INPUT jacks. For high-level, use the HIGH INPUT four-pin connector. Ensure the remote turn-on wire is connected to the REM terminal or use the High Input Auto Turn-On feature by pressing the switch.

What should I do if the PROTECT LED glows red?

The red LED indicates protection mode. Turn off the unit and check for short circuits, incorrect speaker wiring, or overheating. Ensure the amplifier has proper ventilation and that all connections are secure. Let it cool down before turning on again.

How do I set the gain control correctly?

Turn the GAIN control all the way down. Then, set your source unit to 2/3 of its maximum volume. Gradually increase the gain until you achieve the desired volume without audible distortion. The gain is not a volume knob; improper setting can damage speakers.

Can I use both low-level and high-level inputs simultaneously?

No, do not use both at the same time. Use low-level inputs (RCA) when available for cleaner sound. Only use high-level inputs if your source unit lacks RCA outputs.

What is the purpose of the phase switch?

The PHASE switch (0° or 180°) adjusts the phase of the subwoofer output relative to other speakers. This helps to avoid cancellation and improve bass response, especially when the subwoofer is placed far from main speakers.

How do I activate the Auto Turn-On feature?

Press the Auto Turn-On switch. This disables the remote terminal and allows the amplifier to turn on automatically when it detects a signal from the high-level input. Ensure no remote wire is connected.

What is the recommended power wire size?

Use power wire with a cross-section of at least 5mm² (8 Gauge). Connect a 50A fuse near the battery. Always secure connections and use insulating tape to prevent short circuits.

Why is there alternator noise (whine) in my system?

Keep power wires away from RCA cables and other signal wires. Ensure the head unit and amplifier are properly grounded to a metal chassis point. Check that speaker negative leads are not touching the car chassis. Use high-quality shielded RCA cables.

How do I adjust the low-pass filter (LPF)?

Rotate the LPF knob clockwise to set the cutoff frequency between 50Hz and 150Hz. This determines the highest frequency the subwoofer will reproduce. Adjust according to your main speakers' capabilities.

What maintenance does the BAB10 require?

Periodically wipe off accumulated dust from the amplifier to ensure effective heat dissipation. Keep the unit away from moisture, pebbles, sand, or metallic objects. Avoid blocking ventilation. There are no user-serviceable parts inside; do not disassemble.

Installation

PLACEMENT:

The following illustration shows a typical installation. To get the best performance from your AUDIO amplifiers, we strongly recommend that installation be entrusted to a qualified professional. Although these instructions explain how to install AUDIO amplifiers in a general sense, they do not show specific installation methods that may be required for your particular vehicle. If you do not have the necessary tools or experience, do not attempt the installation yourself. Instead, please ask your authorized BOSS car audio dealer about professional installation.

1. Disconnect the negative (-) lead from your vehicle's battery.
2. At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas.
3. Choose a safe mounting location away from moisture.
4. Make sure, there is sufficient air circulation at the mounting location for the amplifier to cool itself.
5. Mount the amplifier such as under the front seat, using the supplied hardware.

CAUTION:

To prevent short circuits while making connections, keep the battery's negative terminal disconnected.

1. When using a power cord, be sure to place the 50A fuse near the battery as show.
2. Connect the lead wire (purchased separately) through which power is supplied directly to the battery's “⊕” terminal only after all the other connections have been made.

The lead wire connected to the +B terminal of this unit should have a cross-section of more than 5mm^2 or 8 Gauge. Be sure to use a ring terminal (optional) for secure connection.

1. If you have any questions regarding the thickness of the power cord, etc., consult your nearest AUDIO dealer.

When connecting a unit without a remote lead (a), connect to the accessory circuit of the car which is activated by the ignition switch. In this case, noise may occur when the car receiver is turned on or off. To avoid this noise, do not turn on or off the car receiver itself. You can turn on or off the car receiver along with the on/off operation of the ignition switch.

If you use car receiver with a remote lead (b), connect to the REM terminal on this unit.

If the PROTECT LED glows red, it indicates amplifier in protection mode. In normal status, the POWER LED glows green. Please ensure correct speaker wiring and connections.

BEFORE CONNECTING: Securely connect all the parts. If the connections are loose, due to contact resistance etc., heat will break out and may cause an accident. Secure and cover the cords with insulating tape and run them under the car mats.

Terminal Connections

When making the terminal connections...

Properly fix the terminal with the screw provided by turning it in the direction as illustrated.

NOTE:

When you tighten the screw, make sure that the screw is securely fixed in place to prevent disconnection of the terminal. Avoid over-tightening as it may cause damage to the screw or its head slot.

Controls

LOW LEVEL INPUTS

Choose the correct length and style of RCA patch cables for your needs. Better RCA's usually have gold plated connectors and multiple layers of shielding for better noise rejection(consult your dealer).

Be careful when running your RCA patch cables. Car environments are notorious for poorly insulated wires. This means that hiss, engine noise, and fan noise can easily be picked up through. RCA cables if run incorrectly. Avoid running your RCA's near large wire looms or electric fans if possible. Run your patch cables on the opposite side of the vehicle as you did the power wire. Be sure to check for correct balance(red is right and black or white is left).

HIGH LEVEL INPUTS

Use the high level inputs only if your audio source unit does not have low level outputs. These inputs may be tapped to the closest left and right speaker wires available for greater convenience.

HIGH INPUT AUTO TURN ON

When the high input switch is pressed. Power terminal REM is disconnected. The power amplifier can be started when the CD player is turned on.

GAIN CONTROL

This control allows you to match the input level of the amplifier to the output level of your source unit. Matching the input can be accomplished in three simple steps:

Turn gain control all the way down.

Turn on the source unit and adjust it to 2/3 of the max volume.

Adjust the gain control until desired volume is achieved without audible distortion.

Remember, the gain control is not a volume knob. Ignoring the three steps above may leave you with damaged speakers and probably a damaged amplifier.

Controls

AUTO POWER ON WITH SMART SENSE

The AUTO POWER ON feature works only with high level input.

Amplifier will detect high input signal automatically. Kindly make sure that REM connection is not connected while using SMART SENSE POWER ON feature.

PHASE CONTROL :

Set the phase control switch to select phase of the amplifier output signal 0^180^

HIGH INPUT AUTO TURN ON:

When the high input is connected, the REM is disconnected, and the amplifier can be automatically turned on.

SIGNAL INPUTS:

These amplifiers have two different types of inputs: Low level Input through RCA jack and High Level Input through a four-pin modular connector. Low level inputs provide an exceptionally clean sound from a source unit through RCA jacks. High level inputs make your amplifier virtually adaptable to any source unit with the use of speaker outputs. High level inputs should only be used when RCA outputs are not available. Under no circumstances should both low level and high level inputs be used simultaneously.

REMOTE GAIN :

User can use external remote control to imitate function of gain control knob

BASS BOOST :

For adding low bass response, rotate the Knob clockwise to add 0dB-6dB of boost centering around 50Hz

LOW PASS FILTER :

Rotate this Knob clockwise to set the required low frequency response from 50Hz to 150Hz
