Yes just one amp. Highs are just connected straight to the head unit. The HU ground was something i was thinking about doing as well. Currently i just connect the black ground wire to the black wire on my cars wire harness. i don't know exactly where it goes to but yeah i was thinking about running the ground wire to its own ground point.Are you only running a sub amp, or are you also running an amp to your mid / highs as well? If so how did you hook up the RCA's? Definitely TRY different RCA's, but don't go ripping them out just yet until you test 1st //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif D@mn sorry to hear about the HU situation, you should've tested that theory swapping the HU's BEFORE you sold it //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif Another thing I'd do is run a chassis ground from your HU to a good solid grounding point somewhere such as a steering column support bracket bolt / stud / nut / etc...
Yes of course. it didn't work. I also tried 2 different HU's and it did it on both. I ordered a new HU and a new set of RCA cables plus ima try ground the HU to its own grounding point. Hopefully one of those fixxes the problem.Grounding your RCA's at the head unit has been recommended twice already.... Have you done it yet?
- Do that 4 sure and if it still doesn't help take a length of 12-14 gauge and just run it directly from the + battery to the constant power of your HU right through your window or door 1st just to TEST and see if there is a change, if there is, then run it properly and be done with it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifYes of course. it didn't work.

with a fuse inline, if it does fix it- Do that 4 sure and if it still doesn't help take a length of 12-14 gauge and just run it directly from the + battery to the constant power of your HU right through your window or door 1st just to TEST and see if there is a change, if there is, then run it properly and be done with it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I believe that falls under running it PROPERLY, as anything ran on the positive side of the electrical system will be fused if ran PROPERLY //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifwith a fuse inline, if it does fix it
