ok so i had a previous post about grounding i got some ideas so i went to try it today
First....i try muting plugs, the amps (speakers) didnt give any noise but i still reground everything tested again with the plugs no noise from amps.
second... i move to the cross over ( memphis 3xo i think) i get noise using the muting plugs so i reground that with 8awg wire. still get noise so i say the memphis "bad" so i put it in a my bro car working perfect. no noise.. even when the plugs are out an the van idling u getting engine noise an all that was connected was the cross over to the amp to speaker rca from headunit was disconnected.
Third.. i run the rca direct to the amp.. head unit to amp, no noise, so i put in the cross an float the rca no power close by still get noise, i ground the rca still get noise, i ground the headunit as well using 8awg wire.
so the memphis doesnt seem to have a problem cause it working great in the car., so i was wondering if its anything to do with the power coming in wether its a smooth DC. i am shooting in the dark,.. so any ideas??
well the problem is not the crossover from what i have tested i might be wrong. but i need it because my bass remote an tuning comes from it an it works great.
