Why Choose This Product?
This amplifier combines a dedicated subwoofer channel with onboard tuning controls, so you can shape the bass signal without adding a separate processor. The continuously variable Punch EQ and adjustable filters offer control over bass response, while the remote lets you make level changes from the listening position.
Its cast aluminum convection heatsink and Class-D design suit compact installations, including tight trunk or under-seat spaces where its dimensions fit. The auto-sense RAP bypass is also included to help with vehicle power-on and power-off behavior.
Installation & Compatibility Notes
Check the available mounting space against the amplifier’s 1.9" x 6.8" x 8.5" dimensions. Confirm that your electrical system operates within 9–16 VDC and plan for the recommended 80 A fuse, which is not included.
The 4-pin Molex high-level input supports factory or aftermarket connections, and the amplifier also has a 2-channel RCA pass-through. Confirm your system’s connections and the subwoofer load before installation; the stated 500W RMS rating is at 2Ω.
