[QUOTE="sdmtnbiker420, post: 2823577, member: 575292"] Just wanted to update on my Pioneer 6900-UB engine whine problem. I grounded the chassis of the deck to some metal behind the dash and the noise got worse, the deck started ticking as well as whining. I took the custom ground off and the ticking went away. Installed a PAC ground loop isolator on one of the RCA's going to my 4 channel amp and the noise COMPLETELY DISAPPEARED! Success! Noise gone completely. I'm glad, because I like the deck and i'm already used to navigating through the menu. [/QUOTE]
