hi can any help me with how to wire in an after market radio in a 2001 voyager. im told theres a built in amp as standard and thats stopping the sound getting from the new unit to the original infinity speakers. where could i find the amp? could i bypass it and run the original speakers srtaight off the new unit? or can i somehow power up the amp to run again as it would with the original radio?
any help would be great.
Thanks.

 

Amps are in each speaker switched on by the NBS relay controlled by the chrysler radio,an aftermarket radio will work if you manage to switch this relay on by some other way. good luck

 

Hey where is that relay physically located? I think mine is shot.

 

Hi I opened the fuse box under the bonnet Grand Voyager 2.5 CRD 2003, the first relay on the right hand side closest to the bumper is the one for the amp, still trying to work out how to bypass it though, got everything working but keep flatening the battery
