I have Eclipse 5341R cd deck - Chrysler Infinity Gold system - factory amp plus sub box 2-12" eclipse with it's own amp.

Has any one had any luck with the line inputs on the eclipse deck. Thought this would be the easiest way to go, but it sounds like crap. Can use the line in on the sub amp for direct and bypass the deck, but no line in on the factory amp. Any suggestions on wiring into the factory amp. There is a converter from the deck to the factory amp.

Can anyone verify if the cd change input on the deck will recognize the signal before I go making a cable?

Thanks in advance!!
