hear exhaust in subs

Bad install. And you are not hearing exhaust through the system. reground everything, separate power and signal wires. Then change the plug wires if you still have issues.

 
i still think you have a bad ground. just because the paint is scraped off doesnt mean its a good ground, if youre on a thin, flimsy piece of the body then its not going to be anywhere as good as what the chassis will provide. also the big three should be done or redone. car companies are great about putting those notched washers that scratch the paint a little bit thinking its a good ground (which it is when all youre running is a pair of head lights) Grounding the headunit always helps, pioneer or not. i have engine whine on my 2008 pontiac with the power and neg running straight to the battery. but not on my bass car. that is the one with upgraded wiring and good grounds.

 
iv re ran the hu ground to the frame as expressed in another post along with the amp ground and iv moved the ground several times as said along with changed out the rca's and even went as far as to install a ground loop isolator. it has to be a faulty ground to case in the hu rca outputs.

:FACEPALM: thats twice this morning. just ground the damn RCAs to the chassis. take a piece of BARE wire. wrap it around the fat part of the RCA (any one of them) and then loosen up a screw on the radio chassis (the ugly aluminum and steel part of the radio) and smash the other end of the wire between the screw and chassis. it should help at least. do that and sand your ground connections under the hood. if it doesnt work youre either an idiot or the amp is a POS

 
why the hell would you make a post on a car when you wont take the time out of your day to read the fing post jack ***, go re read the first page of the thread and you will see that iv said everything you said and that the rca grounding to the hu case is the last thing to do all chassy mounts are clean and wiring is solid. iv left the same answer as you so wtf is your point in posting??? i fell like it must be said again sorry. jack ***!!

What amps are you using to test this out?

bro maybe if you used proper grammar or even close to it i could understand what your post was about/ would bother to read it all. everyone here has given you every possible solution.

 
OP deserves to be having this issue //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Oh, and you're fcuked. There is no way to fix it. Your headunit is about to blow, and it will subsequently take out your amp, speakers, and sub(s) with it. It has already done permanent damage to them, so you might as well just turn the volume and gains to max and enjoy letting all your ish xplod. You can then follow that up by ripping all the hairs out of your scrotum, shoving a cactus up your no-no place, and drinking poison. /thread
