1200W Slim Underseat Subwoofer Amp Package with App Control and Lights

Description

This 10-inch powered car subwoofer is designed for drivers who want deeper bass without adding a separate amplifier. By combining the subwoofer and built-in amplifier in one compact unit, it simplifies installation while helping fill in the low-frequency range that standard vehicle speakers often leave thin. When tuned properly, it can add weight to kick drums, bass lines, and cinematic soundtracks while keeping the rest of the audio clear and balanced.

Its slim under-seat design, measuring 3.36 inches high, makes it suitable for many cars and trucks where space is limited. It can often be installed beneath a seat to preserve legroom, or placed in a compatible trunk area if the vehicle layout allows. Because fitment varies by model, checking available clearance and securing the unit correctly are important steps for stable performance and safe operation.

Installation is supported by included wiring and both high-level and RCA low-level inputs, giving it flexibility with different factory and aftermarket audio systems. Two auto power-on modes are available. In REM mode, the REM wire connects to the head unit’s remote output, GND to a clean chassis ground, and fused +12V to the battery’s positive terminal, allowing the unit to power on with the stereo. In signal-sensing mode, the fused +12V and GND connections are used, and an incoming music signal activates the subwoofer. The manual should always be followed closely, and the REM wire should not be connected directly to +12V.

For sound shaping, the unit offers a 1200-watt peak rating, 300 watts RMS power handling, a 4-ohm impedance, and a frequency response of 20Hz–500Hz. The low-pass filter is adjustable from 50Hz to 150Hz, and bass boost can be set from 0–12dB at 45Hz. A practical starting point is often a low-pass setting around 60–80Hz, then small adjustments based on the vehicle’s acoustics and the listener’s preference. If bass begins to overpower vocals or sound strained, reducing the boost usually helps restore balance.

Additional details include THD below 0.4%, a signal-to-noise ratio above 90dB, a 25A rated fuse, 0.9V high-level input, and 300mV low-level input support. The aluminum-alloy spider-shaped speaker protector and blue LED light ring add a clean visual finish, and the lighting can be switched on or off through the included app, using the manual’s instructions.
