Grounding wire question

[West]

I have a HU that has a grounding cable designed to be connected to the chassis. Can anyone think of a good reason I shouldn't use the grounding cable in the vehicle's wireharness instead?

all manufactures have in there instructions to have your ground to the chassis of the vehicle as that's usually the best ground.

my buddies saturn had the same thing but he ran it to the ground on the harness and it works just fine

I just bought a used deck off of someone and he had the ground connected to the chassis. I am just going to run it to the harness. Hope for the best. The power is coming through the harness, so why cant the ground also.

I've done it before but this is a DEX-P99RS and wanted to make absolutely sure. If I can't find a good ground nearby I'll just use the harness.

Thank guys!

Depends on the age of your car. The ground distribution systems in modern vehicles are purposely designed, and I would use the harness ground intended for it. On older cars (like pre-90) the ground harness can be funky and routed to some god forsaken rusted bolt in the engine compartment... better to make a new ground for those.

I ended up splitting the ground to the wireharness and frame 2 be extra careful. I will keep that info in mind, its definately something to consider.

Best place to ground is chassis
