Very good sound out of this combination. RMS matched very well for amp and sub woofer. I am very pleased with the performance and at such a reasonable price. Would recommend this package.

I would definitely recommend this product for anyone that needs a basic bass system added. Everything was easy to put together and setup. Get a good quality wiring kit! I wasted some time on a cheap one that didn't work. This system adds LOTS of bass! The amp can really push, and the sub performs great. If you decide to upgrade the sub later, you can get a little more juice from the amp that this sub can't handle. But it's a great setup to start with! I'm running Rockford Fosgate Prime speakers and Audiobahn tweeters off of my Sony Xplod head unit, and this sub kit. All works great together!
