I purchased a Sony CDX Gt-520 Head Unit for my car. I already had an amplifier from Interfire and 2 10'' JL Audio Subwoofers. I hooked up everything and it works extremely well with the tuner. However when I switch to the cd player or my auxilary (which has my ipod connected it) the amplifier shuts off and the subwoofers do not play. I have reset my head unit thinking it was a setting but it did not work. Do you have any ideas on what could be wrong? The product underneath is not my product but you couldn't find mine.
I had the same problem. most radios have a power antenna wire and an amp turn on wire it sounds like your amps are being turned on by the power ant wire that loses power when you put a cd in try swapping the blue with blue and white wire this should solve it

Do you have the remote turn on lead hooked up to solid blue wire from the back of the deck? Your amp shoild be hooked up to Bluw w/ white strip as the solid blue wire shuts off when the tuner is off, its used only for the power antenna.
See if a) the head unit has a separate subwoofer output control, and make sure it's activated; b) the amplifier you're using for the subs has the gain control properly turned up; c) if neither of these fixes the problem, make sure all of your amp fuses are intact; d) make sure the subwoofers are in a properly-sized enclosure (too much or too little airspace can affect the sound output).
