Do you have a aftermarket deck? If so there should be a remote turn on on your deck. Other than that just get a multimeter and start looking for 12V switched.G6~Mike said:So today I decided to put the sub from my old caddy into the G6. I ran my remote power wire from the fuse box inside the car to the trunk but didn't have any way to test which wires are switched with the ignition. Anyone here that has put an amp in know which ones are switched with the ignition? Any info would be appreciated as it will save me a few minutes tomorrow when I finish installing everything.
