BOSS Audio Systems BASS8 8-In Under-Seat Subwoofer – Built-in Amplifier, 800W

Compact power, bold bass

The BOSS Audio Systems BASS8 blends an 8-inch subwoofer with a built-in amplifier into a slim, low-profile enclosure designed to slide under a seat or fit inside tight compartments. This space-saving design helps you retain cabin room while adding substantive low-end presence on the road.

Smart power, clean sound

With Pulse Width Modulation (PWM) power management, the system delivers precise voltage and current control, reducing loss and boosting reliability. A dedicated low-pass filter ensures high notes stay out of the sub, delivering a focused bass experience where it matters most.

• Space-saving design: single unit, multiple installation options for tight spaces.
• Efficient power handling: PWM reduces waste and protects components for long-term use.
• Flexible inputs: high-level inputs for factory radios; low-level RCA inputs for aftermarket units.
• Tunable bass: variable bass boost and phase control let you dial in your preferred low end.
• Protection and status: LED indicator plus thermal, short, and overload protection.

Real-world use, real-world convenience

Imagine a sedan, hatch, or compact truck where space is at a premium—the BASS8 adds confident bass without intruding on passenger or cargo space. The included remote subwoofer control lets you adjust bass from the driver’s seat, helping you stay focused on the road while fine-tuning your sound on the fly.

• Install under a seat for a clean, clutter-free look and easy access to connections.
• Pair with a factory radio using high-level inputs, or connect to an aftermarket unit via RCA inputs for flexibility.

Key specs and build quality reflect practical design choices: dimensions around 12.20 inches by 8.86 inches by 2.95 inches, weight about 8.82 pounds, and a rugged aluminum cone with a rubber surround. A 3-year Platinum Online Dealer Warranty (with purchase through Amazon) adds reassurance for those who value dependable support. Results can vary by vehicle and setup, but many users report richer bass control and a more balanced sound in space-constrained environments without sacrificing cargo or legroom.
