[QUOTE="Umbra, post: 8335892, member: 658055"] Your setup is perfectly fine. You can hook up the RCA cables to an output other than the sub output. Assuming this output is full ranged you can eliminate everything you wouldn't want your subs to be playing with the low pass filter on your amp. I did this with a Y-splitter for the RCAs on a lesser HU that only had a single output. shizzzon's concern about your wiring is a valid one. That would be a good thing to work on, not only to track down the problem, but also for safety reasons. You'll want to push as much bare wire into the terminals as possible, then tighten the screws so it's nice and snug (I usually give them a little tug to check). I've had amps that have flat metal plates that clamp the wire in place, but my current amp just has screw terminals. If I tighten them too much they crush the speaker wire to its breaking point, so you need to find a middle ground. You should cut excess exposed before putting it into the terminal, so once it's in, the insulation should run all the way up and there's nothing or almost nothing exposed. This reduces the possibility of shorts. I'd also suggest adding a bit of slack in the cabling. That one positive speaker wire looks pretty taught. One loose wire can make or break your whole project. Aside from the wiring concerns, the ground would be my next point of interest. I know you said you used a ground from your old system, but might we see what this looks like? You'll want to bolt a ring terminated ground wire to unpainted chassis (this might involve sanding). One more suggestion: you can narrow down your search with [URL="http://www.amazon.com/Mediabridge-3-5mm-Male-2-Male-Adapter/dp/B004YEBK66"]one of these[/URL] and anything with an AUX out (like a smartphone or iPod). Hook up a device directly to your amp and you can take the HU and the RCA wiring out of the equation temporarily. [/QUOTE]
