All,

I am really at my wits end. There's not a lot of information to go off of relating to KA9 RL's. Here's my problem, I am tapping the OEM leads before they go into my OEM Amp. In the '04 RL w/ Bose, the HU puts out a four channel differential balanced signal, however, each channel has a neg lead. Essentially, I spliced RCA leads onto the +/- of the front L&R outputs of the OEM source, and then I am running it into an Audiocontrol Overdrive. The Overdrive accepts the differential balanced signal just fine, w/o any noise and outputs a non-balanced signal.

My problem is that the balance is way out of whack. The output on my driver side is easily 2-3x louder than the passenger side. I have triple checked all my my splices and RCA connections, they are all solid. Yesterday I noticed a large wire which I believe is the sheild ground coming from the OEM source/harness. I dont have this connected to anything at the moment. Do you guys think that not having this sheild grounded is causing my balance issue? Should this be grounded, connected to the neg side of the rca connection, or somplace else all together?

I am really out of ideas at this point and will give any and all suggestions a shot.

 

Anyone?
