So i started my first build (where i done 90% of the work) a couple of days ago i've got a RE SC 15 with a 1000 watt memphis PR amp. i drove it for a day after i got all the wires ran everything was fine, well not i have a pulse in my sub. when i went to the car audio store to buy a new dash kit i asked one of my friends what the problem could be he said it was even the amp going bad, the RCA cables or a bad ground. i borrowed some RCA cables yanked out my CD player ran the cables from the cd player to the amp an there was no pulse when i remounted my cd player it was fine then the plus came back. anyone have ideas. the only thing i didn't do with this build is the ground wire and the wiring harness. The guy at the car audio store said i need to run the ground to the frame of my car and that is more than likely my problem but another employee said the ground is fine. i just don't wanna start cutting carpet if the ground location is fine
here are a couple pictures of the build right now
the ground wire is ran to a random screw we found under the seat when it folds up
