ill try and fix this after work and read replys when i get home. im getting very bad alt whine, i put a new amp on my components. i ran the wires on the opposite side of my RCA's and power. could this be a problem? didnt think it would be... but its bad alt whine. u cant hear it after its up about half way, but its loud and distorts the **** out of my sound... any ideas?

If you disconect the RCA's for the new amp does it go away? If it does, try grounding the RCA outputs on the back of the H/U, that's how I solved my problem.

Try revving the engine, this should make the sound quicken its pace. it would be like when you hear a rice burner go 90 down a street when you rev your engine. also try listenting to it with the car off, you may need to wait a few minutes for it to go away if it still persiets. i had this same problem recently and it was two 45 degree angle rcas that had 2 get moved to my HU. easy 2 fix problem but annoying as hell.

well cuz i posted it at 6am. i hadnt even listened to it yet because i got done so late last night, so i went out to my car to check it out before i took a shower and i heard it. came on and posted. didnt even bother to look at any stickies, i was half asleep. i wanted to ask my question and be done. but i fixed it. it was my RCA's. for some reason when i put in my new RCA's i ran them with the power wire. //content.invisioncic.com/y282845/emoticons/*******.gif.a649d21efc0d1fd4890a6428166586c1.gif

signal and power leads should be away from eachother. some pioneer hu's need the rcas to be rounded. try running rcas outside. or you might have a ground loop. how many ground points do you have and is it sanded down cleaned and bolted on right. also check your ground point with a dmm

i got it... my front output was yeilding alt noise. i switched it to rear output, now its fine. ill wait and see if i get any alt noise from my sub output when i get an amp for my woofers. if i do, ill just jump the rca's and use the rear output for both my comps and subs.
