My pioneer DEH-P4500MP head unit is hooked up to my amp, but I'm not getting any signal from it. I have 2 preouts in the back of the head unit (f & r), and the rca cables are hooked up to the rear preout and go into my amp. We tested the system with my friend's headunit and rca cables and it worked fine. Is there a setting of some kind that I'm missing that isn't giving any signal to the preouts? Could my preouts be broken?

I've read through the manual and there is no sub level setting. I've tried both front and rear preouts. All I get is small background noise when I change the volume, or change the fading. It sounds like there is a connection between the headunit and amp, but that there isn't any audio signal being sent.

I tried turning the initial setting of aux on AND off and it didn't make any difference.

There's no setting that will turn off the pre-outs on that head unit, but if you have the FIE turned on there will only be bass on the rear pre-outs, no midrange or treble. Also, if your fader is adjusted all the way to the front, the rear pre-outs will have no sound. If you've checked these settings, and another head unit works with the same RCA cables, then it sounds like your Pioneer has a problem. (If you haven't tried different RCA cables, I'd try that as well).

Have you tried the front outputs? There's nothing in the installation manual that says how they have to be hooked up if you have one amp, but it does show two amps.
"Maybe this unit requires two amps if you go with the external mode." Believe it or not, the unit probably senses the external amp being hooked up to the jacks, and you may need 'em both hooked up for it to work.
Drop a few quarters on 'em. Call (800) 421-1404 Mon. - Fri. 9:00 a.m. - 7:30 p.m. Eastern (all product inquiries).
Good luck.

run a new set of rca outside the vehicle just to test from the amplifier to the radio maybe the rca jack got cut somewhere on the vehicle , if that don't help it is posible that the rca jacks touch ground in your trunk and damage the rca output on the radio for some reason this only happends on pioneer radios
good luck

Re-check your intial settings again. Read page #35 about the auxiliary setting. This uses your RCA jacks as either an input or output. Make sure AUX is set to off.
Turn the unit off. Press and hold Function button, then it will beep. Depress Func. until AUX shows up. Press up/down buttons to turn off the AUX function.
