pioneer ground interference

Well i had a terrible problem with this on my cali profile 2 ch amp. Would have a whine that would alternate with the rpm's. I took the amp and speakers out a while ago because of this. I just did the figure 8 and regrounded my sub and front channel rca. I havnt tried hooking up the cali profil because i am pretty sure i am getting a new kicker for christmas. Is there anything else i can do besides buy a new deck and this figure 8 with copper wire to help solve this problem?

as long as all your grounds are solid, then your only solution with this HU is the grounded RCA's.

Mine has been running for almost a year with the RCA's grounded, and it works great.

ok because like i said i didnt reinstall my comps yet so i dont know if it worked or not. I hope it worked. I cant hear anything comming from the sub, but then again the sub output didnt seem to have that big of a problem with it.
