The perfect blend of value and performance!  That’s exactly what you get from the new Diamond Audio D3 series amplifiers.  With a newly designed heat sink that features 25% more aluminum than the previous generation, these amplifiers are capable of considerably more power than ever before without increasing their overall size.  On board 12dB per octave continuously variable crossovers and up to 12dB of bass boost make them very flexible.  With four models including the 4-channel D3 500.4 up through the monster class D mono D3 1000.1, there are lots of installation possibilities.
