Guest KyleCannon Posted April 26, 2009 Report Share Posted April 26, 2009 So there is only engine noise on the subs but not the mids? If thats the case, check the subwoofer ground and make sure its grounded well. Quote Link to comment Share on other sites More sharing options...

If thats the case, check the subwoofer ground and make sure its grounded well. thanks for the help, i tried changing the grounds already, is it okay for all the amps to share one ground? and when i only have the power wire is on the amp without the ground on there i hear the noise. any help?

Guest KyleCannon Posted April 26, 2009 Report Share Posted April 26, 2009 Try moving the ground to another location if you're using it on the chassis. Take a DMM and measure the resistance from the wire to the chassis as well. Quote Link to comment Share on other sites More sharing options...
