I cannot for the life of me rid my alty whine....please help.

ground my rca's maybe? is that a bad idea?

that would be my next attempt after my advice

Check out David Navone - Car Audio Engineering. I'd recommend either a fully isolated supply or an electronic suppressor to power your HU and any other processing..

ill try grounding the rca's of the midranges (speakers the noise is most audible through).

just secure a wire to the outside prongs of the rca and run it to a secure ground...?

i'll look into that

now do i need to ground both end?

the monster cables i have had a piece of wire coming out of the insulation and i didnt hinkmuch of it. perhaps it has something like you mentioned built in and i should try groundign that wire? i cut it hella short, but im sur ei can open the insulation and find it...

Thats not grounding the RCA cable, thats an extra cable included in monster cables for remote on (at least if its the same monster RCA cables I have)

just searched for ya, this looks right

Its a ground loop. Theres a differential in potential voltage between the radio and amplifier. That causes the noise. If you just ground them at the same place, that would silence it. Even just a better ground for each RCA would most likely do the trick. It did for me.

NO, don't do the above. That would be a problem. If you want to ground the RCA, you need one with shielding that's designed for grounding. (Then you only want to ground one end of each). Since you mention that you've covered your ground connections, what is the quality of your RCA interconnects? Twisted pair work well for noise isolation. On your ground connections, if you haven't done so already, make sure to scrape away all paint and primer, and when possible, use a bolt, star washer, and nut. You can use an accurate DMM to check any resistance in the grounds. Just a few suggestions. These type of issues can and sometimes require several different steps to troubleshoot. Best of Luck.

rca interconnects are monster, stinger, and RF.....all ground spots are sanded and bolted. all other power/grounds are secure as hell.

i'll try the dmm to check ground resistance.

wrap your rcas on a nice thick blanket of foil from where they connect to the deck to like a foot back then tie a wire into the foil, wrap it all with electrical tape and ground the wire. should work fine.

Pics of this? would it help my subs?
