I have a 2001 Grand Caravan Sport with the Infinity system. The factory stereo is dead. I want to replace it but am not sure how to wire the new unit to the Infinity system with the speaker mounted amplifiers.
Has anyone had success doing this?

 

Does your new head end have both high level output and low level output? If so, is the low level output adjustable?

 

I'm still researching decks.
A local shop told me I needed a 4v deck and that of i made sure the amp control wire was wired to the speaker power lead on the harness that it would work.

 

Good idea to do some research before buying the deck. I don't know what 4v means. Volts? Channels? Good luck.

 

Got what I needed from Crutchfield.
Go to their website, select your model with Infinity speakers, choose the head unit you like that comes with all of the harnesses for free and they will send you everything you need plus a thorough list of instructions.
Very easy, works great.
