Stereo Wiring Help Needed... '08 WK with RER/Boston System
So I've gotten knee deep in this, and it's not working the way I thought it would, so I'm looking for some guidance from all the stereo junkies out there. I'm sure it's something simple I've overlooked...
My goal was to maintain as much of the stock system as possible, without splicing wires unnecessarily or tapping in with LOC's as many have done. Plug and play would be ideal, and that is my challenge.
Vehicle is a 2008 WK Overland with the RER NAV and (formerly) Boston Sound-system
*I've searched on this site and other "un-named" sites as well as referenced WKJeeps.*
Upgraded all stock speakers with JL Audio components in all four doors. I had these left over from my last Jeep, which is why I used them. They sound great, and they're paid for.
Installed JL Audio Stealthbox
Bought the Metra 70-6514 harness and a LCi-6 to sum the signals. The purpose was to simply plug this into the rear amp connectors, ditch the Boston amp, and run wires to the LCi-6, then to a pair of JL Audio amps... 300/4 (doors) and 500/1 (stealthbox).
Following the handy pin-out diagrams on WKJeeps, I "tweaked" the Metra harness to capture the incoming front/rear audio signal from the factory Jeep Amplifier Connector C2, and routed them through the LCi-6 to RCA's going to my amps. OK so far... Then using the other half of the Metra harness, ran the now amplified speaker signal back to the factory Jeep Amplifier Connector C1, effectively powering the door speakers. Check.
So now, I've got all four components powered, the stealthbox booming, but I can't turn down the damn volume!
Any suggestions? Who else has completed a similar install, and how did you end up tapping the wires?
