HOW-TO: SC300/SC400 Install Aftermarket Head Unit, OEM Speakers and Sub Working!
#333
That's probably it. I happened to disconnect the RCA cables by accident from the head unit, and it made a pop (sounded ugly). And if only one RCA cable is connected, it makes a humming noise. So something probably isn't wired right...

I have a 99 sc300 and I am trying to install a Pioneer AVIC Z130BT head unit to replace the factory stereo. So far the head unit turns on and I have wired all 4 of speakers straight from the head unit to the trunk as you showed. I am having a real hard time with figuring out how to wire the antenna so it goes down when I switch to sd card, bluetooth audio, or cd mode. My stock harness has 3 antenna wires: ant+ (pink/black), antA (blue/white), antB (yellow/red). My head unit has one blue antenna wire. Please help.
Thanks
Thanks

aside from splicing in to ~"D"~ harness is there any way of hooking up the factory sub woofer amp to an aftermarket head unit?
meaning that i would rather cut up $80 worth of metra adapters them cut the factory wire harness
and thanks to the op for posting this was getting ground interference when the ignition was in the on position (running or not) but not when the switch was in the acc position changed from the factory harness ground and wired to a chassis ground and fixed the issue...

But I don't have my car back yet, so it'll have to wait
