Trying to install an aftermarket amp with an RCA conversion to aftermarket rears and fronts/tweeters.

Just wondering if I can send the remote wire to the XFM box on top of the rear deck or if I can splice it into the factory amp under the dash or if I have to run it to the fuse box location mentioned by someone else...thanks for any help

 

okay...does anyone know if there is a switched power wire going to the XFM unit on the rear shelf of the car?

 

Sorry but I don't have XM in my car so I can't help you. Best bet is to see what connections are there and use a test light or digital voltmeter to see if any of the wires going to it are switched hot.
