So I don't have the normal car audio setup. I have a 65inch TV with a whole car audio setup as my surround sound with 2 12 inch subwoofer. (Not to brag) but basically I have a xbox 360 power supply powering my head unit and 2 6.5 inch speakers. And the same powering my 2 12s. The speakers and stereo never had an issue with. The 2 12s are very low powered because of the 30watt xbox power supply but they surprisingly bump pretty hard. Anyway my power supply for the subs is extremely loud when I turn it on. Before I could unplug it a few times and it would work but now I can't get it to stop. Has anyone else done this setup before and know the issue? It's worked fine for a year just started doing this. Anyone know if the power supply is just done if there's a fix to this?
