The SkinnyThump powered subwoofer delivers deep bass response for trucks, SUVs, and cars where space is at a premium. At just 2.75 inches tall, this under-seat enclosure fits in tight spaces while providing the low-end punch your sound system needs.

This powered 10-inch subwoofer produces 300 watts RMS and 600 watts peak power through its built-in Class D amplifier. The slim aluminum enclosure houses a high-powered 10-inch woofer that extends your system's frequency response down to 20Hz, adding the chest-thumping bass that factory speakers can't deliver.

The Class D amplifier runs efficiently with less than 0.4% THD and includes adjustable controls for dialing in your sound. A variable low-pass filter (50Hz-150Hz) lets you blend seamlessly with your existing speakers, while the bass boost control adds up to 12dB of additional punch. The subsonic filter at 20Hz protects your woofer from damaging ultra-low frequencies.

Perfect for daily drivers who want better bass without losing cargo space, or work trucks where a traditional box enclosure won't fit. The compact design works in crew cabs, extended cabs, and even smaller vehicles where under-seat mounting is the only viable option.

Connect via RCA inputs from your head unit or use the high-level inputs to tap into factory speaker wires. The included remote control lets you adjust bass levels from the driver's seat. Installation hardware and wiring are included.

Backed by Seismic Audio's warranty and ships fast to get your bass upgrade installed quickly. Professional-grade performance in a space-saving design.

Frequently Asked Questions

Will this fit under my truck seat?

The SkinnyThump measures just 2.75 inches tall and 13.5 inches wide, designed specifically for under-seat mounting in trucks, SUVs, and cars. It fits most crew cab and extended cab trucks, as well as many passenger vehicles with adequate under-seat clearance. Measure your available space to confirm fitment before ordering.

What connections do I need to hook this up?

You can connect using either RCA cables from your aftermarket head unit or the high-level inputs that tap directly into your factory speaker wires. All necessary wiring and installation hardware are included. The high-level inputs make installation possible even with factory stereos that don't have RCA outputs.

How much bass will this add compared to factory speakers?

This powered subwoofer extends your system's low-end response down to 20Hz with 300 watts RMS of clean power. Factory speakers typically roll off around 80-100Hz, so you'll gain significant deep bass extension and impact. The adjustable bass boost adds up to 12dB of additional punch when you want more aggressive low-end response.

Can I control the bass level while driving?

Yes, the included wired remote control lets you adjust bass levels from the driver's seat without having to access the amplifier under the seat. This lets you dial in the perfect amount of bass for different music types or reduce it for phone calls and navigation prompts.

Do I need an amplifier with this subwoofer?

No external amplifier needed - the SkinnyThump has a built-in 300-watt RMS Class D amplifier. This powered design saves space and simplifies installation since you only need to run signal cables rather than heavy power cables to a separate amplifier location.
