re need help with car stereo just a shot here but ya never know i once bought a real cheap equalizer power amp for my car tape player at one of those motel room truckload sales and it sounded great for a while that is then one channel quit entirely i opened it up and the amplifier chip for the bad channel had simply melted some of its solder joints attaching it to the pcb i soldered them back and it worked fine i just had to keep the volume a bit lower than i did before probably lousy heat sinking you said a nice alpine which i m sure is a few orders of mag higher in quality than the p o s i had but the point is look inside before you scrap it since you occasionally find something you can repair maybe even the same thing i found good luck
