SUBPULSIX 1600W Slim Underseat Subwoofer & Amp Package with DSP – Built-in Class D, LED Switch, Deep Bass

Upgrade your car audio with the SUBPULSIX 1600W Slim Underseat Subwoofer and Amp Package. This all-in-one solution brings a powerful built-in amplifier, smart DSP, and a compact subwoofer into a low-profile chassis that fits under most seats or in trunks. You get deeper, more controlled bass without crowding your cabin.

Powerful, compact bass for real-world rides

With a peak of 1600W and a high-excursion driver, the system delivers subsonic extension and tight low-end impact. The upgraded magnetic circuit helps produce clean bass that remains articulate as the volume climbs. The result is bass that can be felt as well as heard, yet remains precise across genres.

Smart amplification and tone shaping

This package pairs an efficient Class D amplifier with digital signal processing (DSP) to reduce heat and distortion at any listening level. The system responds in milliseconds, so sudden changes in your music or road dynamics aren’t lost in delay.

• 1600W peak power with a 300W RMS rating for strong yet controlled bass
• DSP-assisted tuning for clean output and minimal distortion
• Low-level and high-level inputs to match many factory or aftermarket radios
• THD under 0.4% and SNR over 90dB for high-fidelity sound

Slim, rugged design built for real vehicles

The slim under-seat design hides a rugged cast aluminum enclosure, delivering robust cooling and vibration resistance. The ultra-low-profile footprint fits under most seats or in trunks, making it ideal for a truck subwoofer, SUV bass upgrade, or compact car installation.

• Cast aluminum chassis for efficient cooling and durability
• 4 Ohm impedance keeps demand reasonable for most car audio systems
• 20Hz–500Hz frequency response captures the essential bass range
• 0–12dB bass boost at 45Hz to tailor impact to your vehicle’s acoustics

Easy control and quick setup

Fine-tune your sound with independent controls for a low-pass filter, bass boost, gain, and overall volume. The upgraded blue ambient light switch works instantly—no app required. Mounting hardware and plug-and-play connections simplify installation.

• Independent controls for low-pass, bass boost, gain, and volume
• Instant blue ambient light switch for quick on/off visibility
• Plug-and-play connections plus mounting hardware for a fast setup

For daily commutes, road trips, or playlist-driven nights, this system offers a practical way to elevate your listening experience without sacrificing space or comfort. The SUBPULSIX package is designed to adapt to a range of vehicle types while remaining a discreet upgrade.
