Hi, I recently just bought a '90 CB7 and it came with a sound system, a Boss PH2.1000 2000 watt amp and a Boss 15" subwoofer and a Kenwood headunit. By the way, he wired it so that even though the car was off and not even in accessory, the radio could still play if you plugged the head into the unit. When I got the car, everything was working fine and I had no problems just playing it as loud as I wanted. But then the aux cord was starting to go out on me, so I replaced it. And it seems like ever since then, the subwoofer doesn't want to stay on. When I first started noticing that it was going out, I took out the radio, set it down and just tried to let the amp cool off. I put the radio back in, and it worked for about 10 seconds then stopped. Now, the subwoofer works to a certain volume when the car isn't on, but only works for a short second after I turn the car on. I replaced the fuses because I wasn't sure about them, but I'm still having the problem. I made sure all the wires were nice and connected. The protection light doesn't come on on the amp. I just don't understand why it was working fine and then it just stopped out of nowhere. I would really appreciate some advice on what to do! Thanks

I would suspect overheating. Most likely the amp isn't sized or ohm'd correctly for the speaker. Repeated overheating can damage electrical components.1993 SE Coupe MRT - 1992 LX Sedan MRT

I agree, try redoing the ground and also set the amp at a quarter gain. if the gain is at full power it will go into safe mode and shut itself off. Another thing that could work is see if the amp is bridged. The amp may not be built to handle that low of an ohm setting. unbridge it and you should be goodTo jdm or not jdm that is the question
