It packs a punch with 300 watts RMS (500W max total power) and features a low-pass filter, wired remote, and bass boost for dialing in the perfect sound.

This specific bundle also includes a 4-gauge amplifier installation kit, so you have the power and ground wires you need to get it hooked up.

It accepts both high-level (speaker wire) and low-level (RCA) inputs, making it versatile for any factory or aftermarket stereo.
