Bypassing JBL: where to tap front door speaker wires?

Hi all, was hoping you guys could help this long time forum lurker. I recently purchased a 2011 LE and now in the planning stage of a speaker upgrade. I've already replaced my head unit so now onto new dsp/amps/speakers. The plan is to completely bypass all the stock JBL stuff and run an active 2 way front stage... does anyone know a good place to tap into the front door speaker wiring so I don't need to run new wires through the door jams? I heard it's a helluva process so I'd prefer not to tackle that at this time.

All the searching I've done in the forums have turned up inconclusive since most were for non-jbl trucks and/or for speaker replacements running off the stock head/amps. Thanks in advance!

There's a connector on the passenger kick panel that has all the speaker wires and that you can reuse to avoid rewiring the vehicle. All the speaker wires run through this connector except the passenger rear door wires if I recall. I did this mod in my 2013 LE a couple of years ago when I replaced the JBL head unit, amp, and speakers. Let me check if I can find the schematics and I'll post them later.

That'd be great... thanks for the assist!
 
Here is some info and diagrams that should help bypassing the JBL components. There are two files attached. One of the schematics has the wiring diagram for the JBL sound system. In this diagram you fill find the flow of the wiring through different connectors in the car. It shows the connector name, the color of the wires, and which pin number they are assigned in the connector.

The other diagram has the actual location of the connectors in the car and the pin layout (with pin numbers and position) of each connector. If you look at the diagrams, you will see that all the speaker wires (except the passenger rear door) flow through the GN1 or GN2 connectors, which are located behind the passenger kick panel. The passenger rear door connector, JN1, is located below the B pillar. I couldn't find this diagram but it's easy to locate once you remove the trim.

When I upgraded the audio system, I replaced/bypassed all the JBL components (Head Unit, Amp, Speakers). I installed a new head unit and a DSP/amplifier under the passenger seat. I ran speaker wire from the amp to the kick panel connectors (and below the B pillar for the passenger rear door) and that was pretty much it as far as wiring for the speakers. I didn't have to run new wires all the way to any of the speakers and deal with the door jams. I also replaced the subwoofer but used the existing OEM enclosure and ran a new line from under the seat to the enclosure.

I'd suggest that you get a speaker test tone generator and insert the leads into the connector pins to test the connectivity to each speaker. It will make things a lot easier to sort out and safer.

Any other questions, feel free to ask.

Good luck with the project and post pics of the work. Unfortunately, I didn't take any.
