Good product.(500 w rms mono block compact) I noticed it has a small fan in it because of the small size and not haveing large enough heat sinks. Fit perfectly under the back seat of my ram 3500. This amplifier is wired to a soar vd-10 d2 wired at 1 ohm. Everything I have bought from skar has been impressive in quality. Have 2 tx 6.5 2 tx 6x9 and 2 tx 3.5 and everything goes together marking a high quality loud system. 6.5 and 6x9 are on a 4 channel keneood amp with 50 rms to each speaker. I have been using skar for a few years now and will continue to use skar in all of my vehicles.
