5v preout and a pac1... to much voltage?


Recommended Posts

Ok guys here's the issue I'm having.

I don't have a ground loop issue. I have a rubbling just from the subs. I have an eclipse 5030 5v preout. Doesn't matter what amp I use the problem still persists. I'm on my 3rd pac1 bassknob. When I'm at 0 on know rumble goes away. If I'm at max on bass knob problem goes away. Anywhere from minimum to max on the knob I get the rumble. Could the 5v preout be to much for the bassknob. This problem happened when I was running 3 sa8's off a rf power 1000.1 amp and my temp setup is a 500.1 JL amp on 2 w0 jl 10's.

Sounds like a bad ground somewhere or maybe noise is being introduced due to the routing of your bass knob. I'd double check the grounding and maybe re route the bass knob wiring. Oh and, check that it isn't nicked somewhere. It's wired with black satin 6 conductor telephone wire isn't it?

Its not a ground issue. I can replace knob and no rumble for like a week or more then the rumble starts. Not being a dick but start your own thread bro

Try putting a ground wire around the ground side of the RCA at the PAC on the input side then switch to output side, see if change in sound. That should help you find your problem.

I will try that bro....but when I remove the PAC the problem never returns. This is what confuses me the most. This is the 3rd one I've installed.

Do you swap RCAs when you remove it? possible bad RCA?
