Capable of pumping out 800W. Low-pass filter, subsonic filter, and low boost circuit. Contains a protection circuit & indicator.

None except the amp gets a little warm after a while which is normal but I thought I'd mention it anyway.

Well I've only had this amp a few days but this amp can really help your subs pound. I was a little sceptical at first but this amp along with my Rockford 10" Sub shake's my whole car pretty good. It even shakes my house a little when I pull in the driveway.
