[QUOTE="OC*SS, post: 8169672, member: 568078"] Hey guys, I've had a power surge problem for some time now. It's only my sub, single Alpine Type R 15 ran by an Alpine MRX-m100 amp. I also have an epicenter, clarion eq, and basic kenwood head unit. It is mainly when I drive on bumpy streets. I get a series of LOUD (like full blast volume loud) bass thumps, like 3 or 4 in a row. Even if I turn the volume, bass level, and epicenter all the way down, it doesn't affect the obscenely loud power surge/thumping. It's extremely embarrassing and random. I have checked all connections from the battery to the sub box and everything in between, and everything is tight as can be. Only place I didn't check is the head unit, as a shop installed everything and I don't know too much about audio installation and how to remove it to check those connections. The shop couldn't figure out the problem. Not sure where to go from here, please help. [/QUOTE]
