With the SBA10A we are introducing 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 SBA10A features low pass crossovers and control for adjusting the input sensitivity from 0.12V to 3.5V. 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.
Mounting the Subwoofer
- Find a suitable location in the vehicle in which to mount the amplifier
A typical location is shown below
- Make sure there is sufficient air circulation around the intended mounting location.
- Mark the location for mounting hole screws by positioning the cabinet where you wish to install it. Make a small mark to identify the position and remove the unit. Thoroughly clean the area you plan to attach the subwoofer, using a vacuum cleaner and press down on it securely.
Control Panel and Features
- POWER ON LED INDICATOR
- PROTECT LED INDICATOR
- PHASE SHIFT: Use this switch to help compensate for time alignment problems in the system. Such problems usually result from having the subwoofer at a different distance from the listener than the other speakers in the system.
- AUTO POWER ON: During ON mode, It’s not necessary to connect the remote cable if you’re using the high-level inputs. Do not function with the RCA inputs. On the contrary, while it is during AUTO POWER OFF mode that it needs a remote cable connection to turn on the unit.
- LOW PASS FILTER: This control permits you to define the frequency range you want the subwoofer amplifier to receive. The subwoofer will reproduce all sounds BELOW the frequency you set. If the rest of your system is weak on the mids, you may wish to set this control relatively high. If the midrange is well covered by the rest of your system, you will probably want the subwoofer to only receive a lower frequency signal.
- BASS BOOST: The bass boost feature will increase the sound level of the bass frequencies
- INPUT GAIN CONTROL: After you have installed your system, turn this control to a minimum. Turn the head unit on (and the subwoofer will turn on via the remote connection). Turn the head unit volume to about 2/3 full level. Slowly turn up the subwoofer input and gain control until you hear a small amount of distortion. Then reduce the level until the distortion is completely gone. Leave the control at this setting.
- REMOTE LEVEL CONTROL PORT: Attach the included remote level control to control the volume level of the subwoofer independently.
- HIGH LEVEL (speaker level) INPUTS: If your head unit does not have RCA outputs, you can use the speaker outputs for the audio source for the SBA10A. Use the supplied cable and connect the outputs properly as shown in the connection diagram in this manual.
- LOW-LEVEL RCA INPUTS: 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
- FUSE: The fuse is rated at 25A. Do not use a fuse with a different value and NEVER replace the fuse with a wire or coin.
- POWER TERMINALS
Low-Level Input Wiring
Low-level (RCA) input wiring is preferred for best audio performance. Most trunk or hatchback installations will require a 15-20 foot RCA cable, while pickup trunks and under-seat installations will require a 6-12 foot RCA cable. Always use a high-quality cable.
Do not connect BOTH the high-level and low-level inputs from your receiver to your amplifier at the same time!
High-Level Input Wiring
The high-level input(s) should only be used when your receiver lacks RCA 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.
Do not connect BOTH the high-level and low-level inputs from your receiver to your amplifier at the same time.
Connect the ground terminal to the closest point on the chassis of the vehicle. Keep this ground wire to less than 39” (100 cm) in length. Use 8 gauge (or heavier) wire.
AUTO POWER ON
During off mode, connect the remote terminal to the remote output of the head unit using 16 gauge (or heavier) wire. Connect an empty fuse holder within 18” (45 cm) of the car battery, and run 8 gauge (or heavier) cable from this fuse to the amplifier ocation. Then connect the fuse holder to the “BATT+” connection on the subwoofer rear panel.

Frequently Asked Questions
Generally speaking, the Low-Pass Filter should be set at a value that is roughly equivalent to (or below) 70% of the lowest frequency response of your main speaker. The frequency response of your speaker, for instance, drops to 43Hz. You should adjust the low pass filter on the subwoofer to 30Hz because 70 percent of 43Hz is equal to 30.1.
One of the most common methods is to modify your subwoofer with filters or phase shifters. Your subwoofer can also receive small improvements to increase its impact. Replace the voice coil, the little cone in front of the subwoofer, or buy a new enclosure for the subwoofer.
The subwoofer in question’s wattage determines its power; a higher wattage indicates a more potent subwoofer.
You can usually rattle the trunk with a 10 inch subwoofer, but you don’t have to crank up the bass if you don’t want to. For crisp, tight, punchy bass that ensures you get the ideal amount of bass for your listening style, a 10-inch sealed box subwoofer is ideal.
We advise setting the crossover for the subwoofer at 80 Hz, though you are free to increase it to 100 Hz if you so like. You don’t want your ear to be able to find the subwoofer, therefore avoid settings above 100 Hz.
A 10′′ vehicle subwoofer is a wonderful choice whether you need to fill a small space or want the most powerful bass. The best alternative will be a 10″ subwoofer if you don’t have much room.
The woofer cones on the main speakers will travel backward while the subwoofer cone moves forward, and vice versa, if the sub and main speakers are out of phase.
Professionals advise that between 60 and 250 Hz is the optimal Hz for bass. These ranges provide the utmost in listening comfort and safety while safeguarding speakers from harm. Outside of this range, listening to bass at too low a frequency can harm hearing.
A 10″ subwoofer will typically need to be installed in a box or enclosure, but you’ll receive bass that hits hard and has the potential to be loud.
A subwoofer (sometimes spelled sub) is a speaker that is specifically designed to reproduce the bass, which are low-pitched audio frequencies. Passive Sub: Passive subs are so-called because an external amplifier or Audio/Video (A/V) receiver is required to power them. Similar to conventional speakers, this.
