does your sub amp have left and right inputs? unplug one and see if the noise is gone. if it is, then you have a ground loop issue (earthing your rca's should fix that)

Wat do u mean by earthing ur rca's?? Wen i had my alpine mrp 500 dint get that noise wen I changed to a jbl gto 12oo.1 thats wen the noise started

did the noise stop with only one rca plugged in?

It seems like the noise itd coming from the sub amp but that noise gets in my 4 chaneel amp speakers so if u turn down the gain on my 4 channel kind off goes away if I unplugged both rca's from sub amp the sound goes away

Bad ground

U think soo globalminds?? Maybe switch the ground to another place strut tower???

 

[Trasero05]

Can it be maybe because my rca's for my 4channel are ran on the same side as my +power wired??

^^ yep, try another set of rca's from headunit to the amp. just test it first to see if it's going to fix the problem
