Impressive amp

I had a buddy getone of these and I put it into a ford explorer that was pusing two audiobahn 12" subs. I did not know what to think when we started, but it really does a great job of pushing those subs. It seems to give very clean power to the subs and it does not break a sweat doing it. I was impressed with the amp.

I Love Kicker

I am using one of these babies for my rear speakers and it pushes them with ease, 80watts RMS per speaker is just what I needed.
