Re: sub turning off on low volume, driving me insane
I got the same problem..
Bought a new Pioneer AVS X3500bhs and a 8 inch powered bazooka.
My bad, I soldered the blue/white remote wire from pioneer to Orange of bazooka but forgot (didn't really know with all the other crap I had to install) to remove the Yellow/Brown loop. Fired up the head unit and the Bazooka would turn off sometimes, then I realized I had to remove the loop. Turned off everything, removed loop, fired up head unit again (orange wire was always connected to blue) but the Bazooka wouldn't turn on. Reset, replug bazooka harness - nothing. Cut the freaking orange wire and replaced loop. Works but with the fustrating low volume crap..
So I thought I messed up something by having the orange wired with the loop on. My bad for not knowing but I do this about once every ten years and at the same time installing camera, microphone, sub, head unit all after work..
Maybe it's the head unit but I doubt it, next I'm gonna try jumping the red power to the orange to see if amp turns on, then maybe the blue remote wire is bad but I soldered everything..
