2003 Mitsubishi Outlander XLS with stock Infinity audio system.
Merta 7003 harness
Clardion nx604 Head unit
Hi,
I have the unit connected to the stock amp with metra 7003 din connector(harness) which is plug and play. The problem is if I have 4 rca jacks connected to the factory amplifier I'm getting only one rear left speaker working and 3 remaining ones have only very muffled bass sound (like no sound). When I disconnect the rear rca outputs I have sound in the front speaker but it's only one left channel in both front speaker (left speaker plays left channel and right speaker plays the left channel as well). It is possible that the head unit is not compatible with the amp ?
