Hertz Performance in a Small Footprint

Thanks to the ultra-compact cast-aluminium chassis (IP64 rated), the HMP 4D amplifier is nature-proof, being the ideal choice for motorcycle installations. It features an incredible power/size ratio and an easy setup thanks to the integrated crossover filter. The Front End section features a complete and bypassable crossover system, providing full system design flexibility with or without external processors, offering the user endless connection possibilities with any source. Inputs feature a special balanced circuitry, ensuring high rejection against electromagnetic interferences, for noise-free results.

TestedWe put this amplifier through a long series of tests in a couple of '18 Harley Street Glides. we found that this amplifier has a particularly low noise floor and a power supply section that far exceeds just about any other micro sized amplifier that we have ever tested. This amplifier is ideal for either speakers with moderate power requirements in 4 channel mode or fro high power speakers with the amplifier in bridged 2 channel mode. For example: JL Audio C1 and C2 series, Rockford Fosgate, and Diamond Audio speakers are a perfect match in 4 channel mode. Or high power speakers like Hertz SV165/St25, MPX165.3, MPX690.3, HMX 8 S, or Diamond Audio HXM8 speakers with this amplifier in bridged 2 channel mode. This makes this amplifier a very attractive choice for a lot of different systems.
