hi guys, my radio has packed up in my p38, it has the hardon kardon clarion stereo in it, i know the standard one is great, but i wanted to fit my tv dvd stereo instead. has anyone fitted a new unit without any hassle, i recently found a radio adaptor off the internet that was easy to fit to my p38 but when i connected it i got some feedback through the speakers. it came with pre out front and rear, and two earth wires but when i connected the earths i still got feedback, is there an easier way to connect a new stereo? i did go and see a guy that aparently knows what he is on about but i didnt trust him when he said i would have to replace all the speakers and run it off a separate amp for it to work, any help i would be gratful. thanks in advance.
