Crossover producing votage on its own?!

**Tim Lake** · 09-06-2007, 09:49 AM

I suddenly started getting a rumbling from my subs even with no music. I disconnected the USB DAC (soundcard) but it continued. I pulled over and systematically disconnected things from the crossover. With no input it still did it but if I removed the outputs, it stops so it must be the crossover causing it. One of my components has now blown so I suspect the crossover isn't earthing and while the subs could take it, the components couldn't.
Does this sound feasible?

Sounds like a either a bad RCA conenction or a bad ground. What brand was it anyways?

Pioneer! I wouldn't expect it from them. I'll double check the grounding, i've had no end of trouble with grounding generally

pioneer is actually notorious for floating ground issues on their head units, it doesn't surprise me. try to ground the outer sleeve of the rca's and see if that solves your problem
