Q&A

When I turn the radio up at all for there to even be a small amout of bass. The Lcd on the radio will flash and the speaker will start skipping really really fast so it sounds like crap. You cant even hear a word before it skips. I would of thought a speaker has busted but all of them do it and it happend all at once. And the radio flashes also. So any help?? oh also the spark plug is working good.
