SnowDrifter Posted May 1, 2019 Report Share Posted May 1, 2019 Could you provide info on how you're wired, how gains are set, and what you've checked so far? ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
kookz Posted May 1, 2019 Report Share Posted May 1, 2019 Your box could have loading issues , one of the pairs are wired incorrectly or it could be an amp gain problem Walled Police Interceptor Four 15s 160s Link to comment Share on other sites More sharing options...

MasterP Posted May 1, 2019 Author Report Share Posted May 1, 2019 Could the rca do it too? Link to comment Share on other sites More sharing options...
kookz Posted May 1, 2019 Report Share Posted May 1, 2019 RCAs can go bad are you running the RCA pass thru one amp into the other or splitting before. Process of elimination maybe try one amp at a time then switch which pairs of speakers are connected to what amp.Will determine if its a RCA signal issue, amp issue or wiring.
