This amp has never been used. I had it bench tested and it sends a pulsive signal when the deck is at 0 volume. Mint condition, but this pulsive signal means there is an issue with the power supply. Can be fixed by Audiobahn and probably wouldn't be much to fix. I will sell for $200 plus shipping or best offer. Send questions and offers to boricua2480@yahoo.com. Can send pics upon request. S/n intact on back of amp.
