Review on Massive Audio PX4R - 250W x 4 @ 4 Ohm, 700W x 2 @ 4 Ohm Bridged, 4-Channel Car Audio Amplifier with ATO, Front & Rear Clip LED by Andrea Washington

I didn't like the fact that the seller put shipping labels on the factory box and shipped it that way instead of in a different box for added weather protection and damage. Another thing is that the amp is made with high quality. Update: Finally got around to installing the amp and the rest of the sound and the amp works fine. My sound is crystal clear
