ToNasty Posted September 19, 2019 Report Share Posted September 19, 2019 Unplugging the rcas cuts the signal to the amp. That's supposed to happen ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
Jreneberg Posted September 19, 2019 Author Report Share Posted September 19, 2019 Right, but if it's a bad amp, wouldn't it make noise all the time? Link to comment Share on other sites More sharing options...
ToNasty Posted September 20, 2019 Report Share Posted September 20, 2019 No because there no signal going to it. No input signal which the amp needs to produce any sound. Atleast that's how I've ways understood it. ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
Jreneberg Posted September 20, 2019 Author Report Share Posted September 20, 2019 So what should I try next? New RCAs? Different amp? I'm open to suggestions. Link to comment Share on other sites More sharing options...
ToNasty Posted September 20, 2019 Report Share Posted September 20, 2019 Run a temp ground straight from the battery to the amp. And see if it does it ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
CstrokerV Posted September 20, 2019 Report Share Posted September 20, 2019 So if you unplug the Rcas from the headunit does it go away? To me it sounds like a grounding issue either the headunit the amp or both also it could be that part of the metal of the rcas contacting something it’s not suppose To.. try wrapping the ends in electrical tape if you can pull the rcas out and run over your interior try that see if it’s still there my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
Casparado Posted September 21, 2019 Report Share Posted September 21, 2019 I bet ToNasty is right. Sounds like it's a ground loop issue. Here's a good article about it: https://www.termpro.com/asp/pubs.asp?ID=121 Link to comment Share on other sites More sharing options...
CstrokerV Posted September 21, 2019 Report Share Posted September 21, 2019 I had the issue the same thing he has from the rca metal part hitting some metal my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
Jreneberg Posted September 24, 2019 Author Report Share Posted September 24, 2019 Tried different RCAs, over the interior, to the DSP, and directly to the amp. Same thing. Gonna try a ground directly from the battery to the amp. Is it okay if I use smaller gauge wire? I've got 0 gauge positive from the battery, but only 4 gauge long enough to make it from the battery to the amp. Link to comment Share on other sites More sharing options...

For testing purposes should be fine, (just don't play above 25% of rated power during test to be safe) but ultimately you need to use the same size ground as your power wire.
