R_Mac_1 Posted February 10, 2010 Report Share Posted February 10, 2010 It's grounded through the engine block. You can just attach the wire to the bolt that screws thru the alt. into the engine block with a ring terminal. That's what I'm going to do to mine when I do my big 3 in spring.

kyleorsini Posted February 10, 2010 Report Share Posted February 10, 2010 OH well that is how i have it grounded right now... I can still hear my engine through the tweeters.. i dont know what to do... that could be a rca issue, a deck rca issue (pioneer pico fuse) if you have a pio deck. could be a ground problem where your speaker amp is.

Gutta Trash Posted February 10, 2010 Report Share Posted February 10, 2010 do you only hear it in tweets? disco them see if u hear it elsewhere if not run a ground from H/U to the firewall. If you do then look for a cut in the power wire feeding the amp it could be getting ingress Quote On 4/20/2010 at 10:06 PM, 'cc_audio' said: Guys are just like girls, once you've had 18 inches you don't go back. 2004 GMC Yukon XL Pioneer AVH-X4700BS 13 band EQ Sub Amp- (2) PPI 5000BD.1 (2) Re SXX 15's 8 cu. ft. box tuned to 32 Hz (4) 6.5 Bose Mids (2) 1" Bose Tweets (2) 1.5" Bose Tweets (1) JY 80 AH w/ new JY busses (1) Duracell 750 up front Apex Alternators 270 A.C.

Red-navi-916 Posted February 10, 2010 Report Share Posted February 10, 2010 ground your rca's but alt to batterie (+) then (-) to chassie then (-) to engine block that shouldn't be your reason for the engine noise tho, if its a pioneer deck then more then im 99% sure its the rcas Quote BUILDLOG http://www.stevemeadedesigns.com/board/ind...showtopic=61862 "98crewcab"Never a POS....just always "a work in progress" lol that's how we roll bitches!!!

John Posted February 10, 2010 Report Share Posted February 10, 2010 It is just from the tweets, there is no cuts in the power wire either! wtf! what do you mean ground my rcas? Do like navi said. Ground the rcas coming off the back of your headunit and it will fix your engine whine. I had the same thing as you with the whine only coming from the tweeters. Cheap fix cured all of my problems.
