2014 Ram with JBL GTO-5EZ problem. PLEASE HELP!!

[rick1967]

I have the uconnect5 with 6 speaker.I have upgraded the speakers to polk audio 6.5 comps in front and polk 6X9 in rear doors and a sub box with 2 10" kickers under the back seat . I am having a problem with my JBL amp . The amp is mounted under the drivers seat and I ran my extension wires from behind the HU . The problem is, with the amp hooked up, I am only getting signal to one of the JBL speaker wire to RCA adapters on the input side(right front). I moved the good signal RCA around to the other input jacks on the amp, and the corresponding speaker will play. I disconnected the RCA's from the amp and hooked up a speaker to each amp input wire(output from HU) and only the front right speaker would play. When I take the amp out of the system and reconnect the speakers, they all play fine . What could be causing this problem? Could it be the stock speaker wiring? I have tried different ground points not helped. I also retraced the speaker wire extensions (16 gauge speaker wire). from the HU for shorts or loose connections . I am stumped. This makes absolutely no sense to me. Is there some weird stuff going on with this 2014 HU? RICK.

I'd like to try and help you but your post sounds pretty confusing. try to break it down again with only the main details.

ps. next time you post something, try to make them as short and to the point as possible. You're more likely to get a response if you make them short and to the point. Otherwise it looks like too much to read and figure out what you need. I know in the process of trying to describe your exact situation you try to include every detail, but it can be overwhelming for people responding and therefore discouraging answers in the end.

OK, let me try explain my problem better. I am running the stock Uconnect 5 head unit. I cut and ran wires from the factory harness to the input of my amp and ran wires from amp back to the factory harness to the speakers. On my jbl amp, they use speaker wire to rca adapters. Problem is that I am only getting a signal on 1 set of rca's. I can disconnect the RCA adapters from the wires and I get signal back to all my wires. It's almost like my head unit is sensing something it doesn't like and shutting down its output. What can I do to fix this? Thankx for any help.

Are you certain you have the speaker wires correct coming from the radio? Positive and negative are together on the same channels? What diagram did you use to figure this out?

The amplifier has the inputs designed to be compatible with factory electronics. Sometimes a factory radio or amplifier will shut off an output if it does not sense the load of a speaker, but JBL accounted for that.

I found a speaker wiring diagram on the dodge ram forum. I am pretty sure That I have them right because I can bypass the amp and all speakers will play.
