I have a 2000 ford expedition 2 amps (mono mtx 4250d or something like that //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif and a mtx 4 channel amp 6304 ) and a new optima (top yellow) new

jvc-kd-avx2 , first i replaced my HU from x1 to x2 (warranty) but the noise didnt stop so then i thought it might of been a spkr or the amp so i changed spkrs and no its not spkrs so i changed amp its its not amp!!!//content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif i'v had this set up for a while first i changed batter (old one was bad) then i changed the HU to the x2 then spkrs then amp so i really dont know from here what else it could be , any thoughts ???? before i replaced my head unit its the same noise
