The All New HS4 Marine amplifier 
HS4 = the 'H' stands for Holy and we'll leave you guessing what the 'S' stands for. We gave it that name because that was our immediate reaction when we first heard it. We tooled this Die cast 4.5lb monster of an amplifier to withstand the rough and tough environment it is meant to work in! The HS4 is a 4-channel full range amplifier with fully variable high pass and low pass crossovers. These enable it to drive our NOAM N5 speakers and other full range speakers or subwoofers.
