I'm searching high and low for a way to upgrade my stereo system on my 96' Interstate. I've changed out the front speakers for J&M and added J&M rear speakers... it helped and clear radio stations sound good but finding a decent clear radio station around here that plays decent music is somewhat difficult to find... so I purchased a Ram mount for my iTouch and a wireless FM transmitter - the transmitter was a complete waste of money as it doesn't perform well at all, to much interference. So I've recently purchased a 100 x4 watt Polk Audio marine amplifier and a Audiovox wired inline FM modulator. Now, my dilemma - how to connect the amplifier up to the stock stereo system - are there "line" output connections...preferably RCA? My other option was to just bypass the stock stereo unit, connect the speakers to the amp - run a line directly from my iTouch to the amp and play it that way but I'm thinking one day, I would like to listen to the radio! Of course, I could get XM! Any suggestions would be greatly appreciated.
