the ****in alternator whine is driving me insane. whats causing this? ive heard of poor grounds shitty amp design... ah idk but it sounds like poop
i checked the ground on battery and its fine. i think ill rip carpet apart and follow the ground, today or tmrw. thanks for the inputI would check the grounds, like follow the ground from the amp to see where it goes and try another point, make sure it is good solid tight and not on a painted surface. also check the ground at the battery to make sure it is good
im a dumbass, whats the rca cables... the channel cables to the speakers?it could also be shitty rca cables, try grounding the outer ring of the RCA cable...i just folded a few strands of wire inside the cable and plugged it into the back of the HU (making sure that the wire only came into contact with the outside contact) and grounded that...voila no more whine
lol damn dude thats quite a vent there, haha they have always been great to me and done awesome work.Did you take it to LG music and stereo? Oh god no! I took a car there for an install and lost hundreds because they didnt order nor use the harness I paid for. They stole my money and wouldnt return my money or fix the problems. Sorry, just had to vent. Those guys dont know theyre head from there ***. You would have been better off asking us on CF for advice and done it yourself. Hope you find the problem, and dont take it back or at all to LG music and stereo.
thanks i will experiment with that when i have the truck torn apart tmrw lolsee if doing something like this will cure it for you, it could be done on the amp end as well and connected to the black/ground cable

this was done like wednesday of last week. and yeah im not gunna go tearing everything apart but i just wanna check out the main groundhow long ago was this work done? instead of ripping it apart yourself take advantage of the warranty most shops issue with an install.
also make sure they rca cables are run atleast a minimum of 12 inches away from the power cable. Preferable on the other side of the truck.
if the shop used any decent brand RCA's then running them next to the main power wire should have no effect on the sound. if they used the cheapest RCA's they could find then it could be an issue.if its a whinning noise that is coming from the speakers and it gets louder the more you hit the gas, its going to be the RCA cables are too close to the power cable. take it back to the shop and have them run it on the other side of the truck.
