LobsterClaws: I'm wondering if you have a step-by-step to access one of the rear stock "subs" wiring. I can't seem to get anything apart in that area. I want to see if I can fill in the 20-40hz range that's missing in the stock system. I've already seen pictures and diagrams from the service manual posted elsewhere but that hasn't gotten me anywhere. I have a lot of experience gutting other cars and systems but the jag seems more complicated...
