Aluminum: Modern Design Hifonics Heat sink for Superior Heat Dissipation. 1x Hifonics ZD-1750.5D Amplifier. Electronic Equalizer. Five Channel, Full Range, Bridgeable, Mono: Flexible installation allows this amplifier to run in four channel or bridged mono mode.
Obviously, you can spend a lot more on an amp and get better quality, but for the price, it actually sounds pretty good and has more power than expected. I have it running a set of 6 1/2" separates in the front, 6 1/2" 3 ways in the back, and a single DVC 10 running at 1 ohm on the sub channel. It has decent sound quality and good power.
