I want to play my mp3 player in my car using an Audio In cable. Would it be possible to find an Audio In port on the back of my stereo? How difficult would it be to take the dash apart to get to the stereo?
Thanks,
Jason
Jason, some vehicles can play an MP3 player using the audio in cable but it may require some external module or special wiring. Unfortunately, we don’t have the specific information you’re looking for but maybe someone from the Modified Life community can post that information here. Hope this helps. Good luck.
it is not that hard but Modified Life was right, it needs special wiring. sorry.
I was just analyzing the wiring behind my factory radio to ensure that I received the correct wiring harness to hook up my Pioneer radio. I noticed that there was another set of wires running into the factory unit. Are these special wires that need to be considered or are they just the wires that run to the radio controls on the steering wheel?
I’m trying to install an aftermarket amp/subwoofers to my 05 Grand Prix GTP, factory deck. where is the best place to connect the lead wire from the aftermarket amp? Any correct information would be greatly appreciated.
AJ King, technically you could connect your 2005 Pontiac Grand Prix amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2005 Pontiac Grand Prix is on and off whenever your 2005 Pontiac Grand Prix is off. Just make sure to run an in-line 1-amp fuse on the amplifier turn on wire. Hope this helps. Good Luck.
