Hey Linty thanx for responding I just finished my almost complete overhaul of the audiophile system in our edge. All new speakers, sub, 2 amps, sound processor, and a small cap, with the factory head unit. We did not want to lose the completely stock look or in dash 6 disc changer, and messing with steering wheel control adapters is a annoying. It is still tedious work to wire the speaker output wires to the processor, then the amp to the speakers, but at least all four speaker wire twisted pairs are accessible in one spot thats easy to get at. The RE-Q5 is perfect and the system sounds amazing. If anyone would like any pictures, or has any questions let me know. I built a custom amp rack that is fit perfect under the rear floor without having to raise it, and a box that fits behind the rear panel and actually mounts to the factory enclosures cage nuts with 1" L brackets.
