Like the title says...the power suprized me. I pushed my two 10 inch subs great!!! Good deal and it is small enough to hide if you don't have a lot of room.

I highly recommend this package, build yourself some big 1.9cuft vented boxes and they thump, very accurate bass. That said i dont think the 350watt amp is what these speakers want, i got a 1000watt amp and it (ofcourse) really took it to the next level, and they handle extra power very well. had them for about 8months now and still booming.

Bought this to put in the wife's expedition. I thought that a vehicle so big a couple of 10's would give it a little bass, but I WAS NOT expecting to feel slight air movement! This amp did a great job on the 10's that came with it!
