Hertz HCP1DK 1240W RMS Class D Monoblock Car Subwoofer Amplifier

Bass upgrade

Putting together a serious bass system? Hertz's HCP 1DK mono subwoofer amplifier will deliver up to 1,100 watts RMS to your subwoofer, improving the sound of your bass as well as your listening experience. The amp's onboard variable low-pass and subsonic filters plus a variable bass boost all help your sub sound its best. You can also adjust the phase of the bass signal to optimize the sound for your listening position. An optional HRC wired remote control lets you control the bass level from the front seat.

Works in almost any system

This amp will work with an aftermarket receiver using RCA connections, or a factory radio using speaker-level wiring and Hertz's ART™ automatic remote turn-on system. The HCP 1DK features preamp outputs, controlled by a variable high-pass filter, which can be used to send signals to an additional amplifier in a larger, multi-amp system.
