I'm only selling this amp because it's too bulky for my new car, it used to be in a truck. - There are absolutely no problems with how it runs, I was very happy with it in the 2 years I ran it. - The original cost was $700, I have receipts for proof. -I'll throw in the 0 gauge copper wires for free (which cost another $100 originally) It's 6500kw, which is extremely powerful. -I had 2 10" competition grade subs and one 12" Alpine running off of it, this set up shook the dishes in people's houses a couple doors down at 1/3 volume! -It does have a couple very minor scratches on it. Call, text, or email me if you're interested. 250-802-7362
