Hey all!

Picked up a 2013 JK Sport in September, my first Jeep, and I am loving it so far.


Hoping for a bit of guidance on this one. I have the stock upgraded sound system, with the bigger touchscreen and factory subwoofer in the back. Assuming I have the stock amplifier as well, this brings us to my issue:

- Today the speakers stopped putting out any sound at all. Nothing, not even white noise. No source plays any music.

Unhooked the battery for a while and let it sit, but it still isn't putting sound out. I tried resetting the radio through the settings and that didn't do anything, either.



SO, where does that leave me as far as options? Looking at OE replacements, I'd be lucky to slide in around $275. Am I able to remove the stock amplifier and replace it with another? If so, what kind of amplifier do I need? I'm guessing I'll need to pickup a CANBUS adapter off Crutchfield to retain my steering wheel controls. Really not sure on any of this - I am NOT a sound/speaker guru!!


Thanks all.

What system do you have? If you have the factory alpine audio, the amp is located right behind the drivers side front dash speaker right above the ODBII port. I removed my amp and replaced it with a RF PBR400x4D and mounted in the same location. How is your radio connected factory wiring or low outputs (RCA cable)?

Yes I do have the Alpine system. Was this RF amp plug and play? Did you need a CANBUS adapter for the steering wheel controls?

I have all factory wiring right now. Not entirely sure what to buy.

Check the fuse for the battery power to amp

That was the third thing I did. The first two were, in no particular order: switching sources and swearing!

The 30A fuse, located M12 in the fusebox, is not blown.

Next try hooking 1 to 4 speakers to the output from radio with amp unplugged

The radio has 4 pairs of speaker level outputs unless it sees the amp on the can bus

If it sees the amp the radio changes its output to just two pairs of constant level output and all fade balance volume and I think tone radio head user set inputs are sent via can bus to amp

Unplug the amp and radio acts like a normal radio without an external amp

You can look up pinouts and wire colors for radio and amp connectors here

Unplug the amp from where? Just unplug everything going into it? The power on the amp or whatever plug it goes into the back of the head unit?


I'm a little confused here

Things got interesting today.

I pulled the panel off underneath the steering wheel to verify the amp was there....it was not. In its place is a 'SmartStart' module, which I'm guessing is for the remote start. Attached to it is a small black relay looking thing that says 'iDataLink' on it.

I should mention that this Jeep came from Canada. It is a Sport trim with some options. It does have an Advent stereo and an Alpine subwoofer in the back. There is no mic for the Bluetooth stereo, so callers cannot hear me when I talk. So my best guess is the stereo was added after the fact? It has navigation, but it's stuck to somewhere in Quebec, and doesn't register in the United States.

So then I tried pulling the glovebox, thinking maybe they installed the entire Alpine system after the fact and it....also was not there. So I'm at a loss.

You probably have an aftermarket radio. Good thing you have a jeep and it's easy to remove carpet and trim. Take off the dash it's simply 4 screws (3 if you do have a aftermarket radio) there will be rca cables in the back of the radio unit, if you follow those wires you will find your problem.

Completely added a brand new system to my jk, new radio unit,speakers,tweeters, amp,subs,crossovers and etc. All factory wires are deleted and new speaker powered by amp. Also running the maestro data link to keep my steering wheel controls. Installed my own auto starter. To me it sounds like either your amp is shot which isnt a hard fix or it could be a wire issue. Rca cables, etc. However you need to locate your amp.
