justin0943 Posted July 13, 2017 Author Report Share Posted July 13, 2017 update took my 3.5mm to rca adapter as soon as i hook up 1 rca it whines that's with nothing plug in to the 3.5mm yet just the rca and I know the amp good because I test bench it on a power supply with no whine so I'm leaning more tours the alt being bad even though its works fine. 02 dodge ram 1500 reg cab 3rd gen 2 sundown sd-2 d4 soundstream rub1.2500 amp all sky high car audio-fuse,fuse holder,wire,ring lugs and rca flex tech box design by Joe X supension-mcgaughys 2in drop spindal ,western chassis 6in flip kit,buddy custom c-notch 04 5.7l hemi motor swap and made it an slt eletric everthing youtube channel-http://www.youtube.c...43?feature=mhee http://www.stevemeadedesigns.com/board/topic/190882-02-dodge-ram-1500-3rd-gen/ Link to comment Share on other sites More sharing options...
reedal Posted July 14, 2017 Report Share Posted July 14, 2017 Did you actually hook up the other rca to your amp and 3.5mm to your phone? If not, I'd recommend doing that. Just because you half ass tested it and got noise doesn't mean the test failed. I've never had an aux cord that didn't have some kind of noise if connected to an input with no source. They pick up a lot of noise. If you think it's your alt, then the next step would be to test to make sure. Your ignition has three resting positions: off, acc, ign. Turn the key once to ACC, radio comes on, amps turn on. If the noise is there, it's not your alt.

CRich614 Posted August 1, 2017 Report Share Posted August 1, 2017 I'm having the exact same issue. I planned on getting a more powerful alternator anyway so hopefully that fixes it. Link to comment Share on other sites More sharing options...
