PowerBass XMA-2405IR 2ch 800 Watt Compact Amplifier The XMA amplifiers carry on the tradition of looking good and sounding great while taking up less space than any other amplifier we have ever offered – and smaller than most amps available from the majority of our competitors’ at the same output levels. High efficiency FRD (Full Range Digital) technology allows these amplifiers to operate at well over 85% efficiency. Limited space no longer means sacrificing great sound with the new PowerBass XMA Amplifiers.
