The bottom half of the truck was underwater for a bit and the speakers stopped working (everything else is fine). I've replaced the head unit with an aftermarket deck and bypassed the front speaker amps and put in new speakers. Front speakers work fine and the tweeters would work if I wired up the amp bypass (I found the post by Spillage) but I decided not to use them. The rear speakers don't work and I can't seem to find an amp for them (they also seem to have the same coloured wires on both sides). I've seen that in the '99 Ram, the front amp actually connects with the rear speakers but that doesn't appear to be the case for the '98 (not enough wires). How can I get the rear speakers working?
