My stereo has been getting really crappy reception lately, where it sounded good, now i get static on 2 different stations, 106.5 and 100.9, but if i go to 92.1 it sounds great.... and the stereo just acts weird, no sound until you turn it off and back on....

My speakers have what sounds like a bad woofer cone, when the bass hits and the truck is OFF only, they sound like crap... but if the truck is running, they sound good. The rears worse then the front.

i dont have a ton of money, around 2-300 bucks, I can deal with the stereo, i like the stock look, and the 6 disk changer too much to give it up. Are the speakers hard to change out yourself? I dont want to run amps or anything, just want it to sound decent.
