Hertz HMP 4D - Compact 4-channel powersports amplifier — 50 watts RMS x 4

Compact power you can hear while splashing

Hertz's incredibly tiny and powerful HMP 4D 4-channel amplifier will add new clarity and impact to the basic sound system of almost any kind of vehicle on land or sea, and it'll fit in a lot of places where space is tight. This marine-rated amp will pump up your system with 50 watts RMS per channel — more than twice the power of most car stereos or marine receivers. You could also bridge this amp to power a couple of subs or high-performance speakers with up to 130 watts RMS each.

This tough guy will make it through the day

The HMP 4D's compact cast-aluminum chassis features IP64 rated protection against water spray, ASTM-D4329 rating for UV resistance, and ASTM-B117 rating for salt fog operability. Balanced high- and low-level inputs ensure that the amp will work in almost any system noiselessly, with no interference. Selectable high- and low-pass filters can tune the music to fit your speakers for superior sound quality.
