Default good place to ground the headunit?

i've installed an alpine headunit and in trying to track down a slight hiss i decided to make my own ground rather than use the stock wire harness, so i grounded it to the chassis over by the drivers left foot behind that kick panel, it was the only clear ground i knew of.

well i put it all back together and now not only is there a slight hiss but there are slight popping noises every once and awhile.


so i guess i get to do the whole grounding thing again ... i assume i should ground it to the chassis closer to the headunit using a shorter and maybe a thicker wire, right?

where should i ground it to closer to the headunit? are there any good spots right there?

You could run a wire down towards the transmission tunnel and theres a few spots on there in the center to ground it. Just get a 3/4" self tapping and make sure you get good connections. This way, it's out of the way, easy to access and works!

Any where that is bare metal, mine was under the driver seat, I had to cut a small hole in the carpet and grounded it to the metal on the floor board.

All stock wiring for the HU here with no noise at all. This hiss is present when the engine is running right? Or is it present at all times...
