I have an aftermarket Kenwood KIV-701 installed in my 05 Elise by the previous owner. As far as I can remember the rear speakers worked just fine in the past but recently I noticed that only the dash spears have any sound coming through them. I have downloaded the manual and can't find any setting that would suggest they are disabled via settings/software. I pulled the unit out of the dash and the wiring, while not exactly pretty, seems solid. I'm working on pulling the speakers and trying to string a multimeter far enough to test from the plug out to the speakers but does anyone have any ideas? I can't find much but it looks like the wires just run straight down and through the center tunnel with the shifter, if there is a break in the line does anyone have any thoughts as to the most likely area where both would be severed? The fact that it's both makes me think it's either a cut somewhere along the lines or an issue with the setup of the unit, but neither is really panning out as I look into it. I'm open to ideas on things to try and next avenues to check.
