I've installed a JVC aftermarket radio in my 98. 5 RAM - to give front panel AUX input for my Sirius radio, MP3/CD playback, and mostly just for fun. The front door speakers work fine on the OEM radio, but I can't get them working with the JVC. I've checked wiring, tested front/rear spkrs with a 1. 5VDC battery, but no luck on the fronts (rears are fine). I've bypassed the new connector adapter, going 1. 5VDC straight to the old connector for front speakers, but not a peep, again rears are found OK. Wiring diagram on top of OEM radio follows same standard as new connector diagram. Anything special about the front door speaker wiring I'm not seeing? Thanks.
