Show original supplier description

The Kicker 46CXA4001 mono Class D amplifier is engineered to provide significant power for your subwoofer, reaching up to 400 watts at one ohm. Its efficient Class D circuitry and advanced internal components contribute to its high power output, while the sophisticated heat sinks ensure cool operation. This amplifier offers extensive tuning capabilities, including a variable 12dB crossover, a 24dB subsonic filter, and Kicker's KickEQ™ feature, which provides up to a 6dB variable bass boost at 40Hz. Flexibility is a key feature of the 46CXA4001, as it accepts speaker-level input signals up to 40 volts (400 watts), making line-out converters unnecessary and maintaining optimal sound quality. It also includes full-range, RCA pass-through outputs for easy system expansion with additional amplifiers. Installation is made easier with a small footprint and included hardware for vertical mounting, offering an alternative aesthetic. An optional CXARC Remote Bass Controller (sold separately) allows for convenient adjustment of bass levels directly from your dash, catering to different music choices. The amplifier also features a three-second turn-on/off delay to prevent interference and FIT+™ (Fail-safe Integration Technology-PLUS) to ensure compatibility with nearly any car stereo system. Kicker backs this amplifier with a two-year warranty when purchased from an authorized dealer.
