Re: Recurring problem with both El8a and BTA8100
Ty for your response. I worked on system yesterday and after playing with all wiring (new harness from new BTA8100) I am convinced it is subwoofer preamp signal from deck. I will confirm today by using preamp signal from rear speakers (which I know to be working). BUT pls expain a bit more about checking ground. I have a meter from radio shack use ohm or dcvolt and where should I check... at connection site or in wire itself running to sub?
