Hertz HCP4D 1160Watt 4-Channel D-Class Amplifier

Power upgrade

Hertz's HCP 4D four-channel amplifier will deliver 70 watts RMS to each of your vehicle's front and rear speakers, improving the sound of your audio system as well as your listening experience. This versatile amp can also be used to run a pair of speakers with the front channels while sending 260 watts RMS to a subwoofer from the bridged rear channels. A variable bass boost on the rear channels helps your sub sound its best.

Bi-amp a 2-way active system

The high- and low-pass filters of the HCP 4D can be set as high as 3200 Hz, so you could use the amp to power a couple of tweeters with the front channels, and a couple of woofers with the rear channels, and gain more control over your system's different tones and levels.

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. If your receiver only has a single L/R output, you can engage the Mono buttons on the front and rear input channels so the amp can power your four speakers from those two inputs.
