[QUOTE="keyofmiracles, post: 8687902, member: 678351"] Hey guys, I'm pretty much a newbie when it comes to stuff like this so bear with me. So the vehicle in question here is an '06 Nissan Pathfinder. I changed out the stock head unit and replaced it with a Pioneer DEH x2800UI and wired it using an aftermarket Metra harness. However it didn't have a black wire, so I had to ground the black wire from the radio to this metal bracket behind the head unit, and I did so by screwing the bare wire down with the screw that was in the bracket hole already. Ever since then the audio will be great at higher volumes for a good while, but eventually, no matter how long it takes, the audio starts to distort and get super fuzzy when a certain frequency of bass starts to hit. I can't seem to figure out what is going on. Is it my grounding location? Is it the way I grounded the car? I've: -Redone all the wiring for the head unit. -Changed head units. -Plugged in the antenna using an adapter, as I heard that the head units also ground through the antenna in these cars. Also when I use the balance and fader controls to divert all the audio to either the front, the back, left or the right one at a time, the bass doesn't get messed up like I described above. With no change whatsoever. Please help me, it would be appreciated greatly. Thank you! [/QUOTE]
