Wrong item
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Salesperson ordered a car amp when I had told him I needed a home amp. It was very easy to return it and get the correct amp, So overall it turned out fine, since I don’t live very far from Best Buy.

Once I got it going again the sun blew. So I ordered a bigger amp an sub now both work great. I just installed the new sub in the ported box for the sub I got from Best Buy.

||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Amp does not power as it states. It keep going into safety mode even with the bass low. It did not work properly for me. Might work for a small single 8 or 10 inch sub but would not power 2 -12's.
