Yes, I replaced it. However..... Well, I can get the amp to work, but only for a few seconds, then I hear the relays click and it goes off. If I turn the power back on, it comes on again, but only for a few seconds. It's as if something is overheating or something and turning it back off... I'm at a loss. My only thought was that I may have too much or too little heat sink compound on the amp chip I put in.
