Hurtin' feelings errrday.
Have a Alpine o/s 7995 which I recently bought which is hooked up to a Massive Audio NX5 5ch amp. The problem I'm having is the sub level +15 on the HU doesn't work. I had another Alpine different model # same problem. This is in my '92 s10 blazer. I also have same brand 9835 in my Tahoe...on that one, works great. I have tried fiddling around with it, tried this/that and still nothing. What could the problem be?
