so yeah like the title says
thats my problem
if the car is off its fine
but when the car is on it makes a wierd humming sound
it sounds like its from the speakers
i checked all the wiring and its cool
my sub does the sound too
i think its like a ground issue
but not sure
any input would be great!

i highly doubt it, car starts up fine.
i believe it to be something with the ground or the factory wiring or something drawing to much power aha.

check your engine grounds in the bay, one might be frayed or broken off. check your battery grounds, radio ground, etc.
a little tedious but easily do-able w/ a multimeter.

Does the humming get louder or go up in freq at higher RPMS?
Could be engine noise due to bad ground on motor, I had the same problem a while back.

^^^ could also be your remote wire being ran next to your power wire. ive had that fix that problem in some friends cars a few times

Maybe it's that?^
Or a bad ground.
Maybe try changing out the headunit?

the humming noise might be a fuse, my friend has that big fuse on his car so it hums freaken loud when he drives and accelerates

it's interference from part of the electrical system in your car bleeding into the sound system. if it comes out all the speakers, it's probably in the headunit, or the signal wires running to the amp. can you list your entire sound system? you'll probably just have to move some power wires away from your sound system wires.

I had to use a noise filter on my setup to get rid of the damn sound . I got it from my local car audio shop if all else fails i would try a filter .

well thing is it was fine up until i started installing the digital climate control and well yeah so idk wtf is up ima try insalling a bigger audio fuse maybe a 35 in place of the 10

are you popping fuses? if not, a bigger fuse isn't going to do much if anything.
i'd look at the wiring for the climate control and make sure none of it is dangling around the stereo or running parallel to the signal wires for the stereo.
I cast my vote in for bad ground, and it may not necessarily be directly to do with the stereo.

Also if you have any power wires running next to or crossing over speaker wire make sure they are crossed like this + (90°) and not like this \/ The way power travels through wires, if they are too parallel to one another the power wire can "bleed" into the speaker wire and that's were the interference (humming) comes from.
