A buddy of mine hooked up two Jensen 6*9s behind my bench seat in my truck in little wood boxes. Then he threw on a Road Gear 250 W Amp and I had a decent sounding system. Nothing too awesome mind you, but it worked. Well, today I was driving around, and I noticed that now any song that has ANY bass to it what so ever causes those speakers to distort with a static like sound. I'm trying to figure out how to get it sounding right again. I've checked all the wires and they're firmly connected to the amp and the speaker. What could have caused this?
