Mason Poston Posted September 16, 2017 Report Share Posted September 16, 2017 Just a rundown of my system real quick. Stock alternator, big 3 up front, 0 gauge ran to behind back seats to a shurikan 600. From the 600 there is 0 gauge ran to a Rockford fosgate punch 1000.1 and a Rockford fosgate punch 600.4. Sub is a Sundown x15 and my kids and highs consist of 4 Crescendo pwx 6.5s up front and 2 in rear and the front also has 2 Crescnedo super tweeters. When I turn my input level up on my 4 channel there's a hissing noise that gets louder with turning it up and gets loud when rpm increase. Super stumped because I'm not sure why and I've checked grounds over 1000 times and RCA runs are separated. Any help? And headunits is a pioneer appradio 3 ran to a DB drive eualizer I'm not sure of the mode. Link to comment Share on other sites More sharing options...
bluethunder Posted September 17, 2017 Report Share Posted September 17, 2017 Try bypassing the eq and see if the problem still persists. It's possible the eq is inducing noise. Link to comment Share on other sites More sharing options...
