I got this amp a while ago and its awesome. You can't ask for a cleaner sound... Plus it packs a punch...I put this against a 750 rockford and a 750 kicker, it just blew them away both going to the same JL subs... I had it with some kicker 15's but I sold them when I got a new car... I am about to hook up two alpine S to it.
