    My sub has a constant hum even when it is not hooked up to anything except being plugged into the wall. I tried using a cheater plug, plugging into different outlets, different houses. I'm thinking the amp might be bad. Problem is that this is a DIY Tempest sub i bought 3 or 4 years ago and I can't remember the guys name lol. I know its not under warranty but i'm hoping he could help me fix it. His name is Darren I believe and lives in Washington State. I am pretty sure its a Parts express amp. Would it be possible to order one and replace it myself? Any help on this issue would be appreciated. Thanks.

    I found Darren Thomas's info and e-mailed him with the problem.

    Darren is trying to figure out what this could be. Anyone have any ideas?

    I had a PE 272w amp that developed a hum and after a couple of months shorted out, smoked, and died. Luckily it didn't hurt my driver. I replaced it w/ a 300w digital BASH amp from PE and have been pretty happy with it.

    I think your assessment is correct, that it’s bad. It shouldn’t hum with nothing else plugged into it.

    Is the hum loud? Is it coming from the amp or the driver? My PE amp always hummed, but it wasn't obnoxious unless you were sitting right next to it in a quiet room.

    Could it be noise from a dimmer or other components in the house or noise on the line?
