ground run question

[jeyventura 10+ year member]

Hi guys got a question here.

I once read somewhere that your car chassis only equals to a 2 gauge ground,

its that correct ??

Soo if i have a 0 gauge run to my distribution block i should run another 0 ground run to the batt or should i ground to the chassis??

Will be close to 300 amps draw at maxx

chassis is fine but a dedicated ground will never hurt //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

uh, im gona have to say no.

your best bet is to run the ground from front to back. But grounding to the frame will work. My car was setup with the ground to the frame, but i had alt. whine pretty bad.

rca getting power interference maybe?

yes that my guess but im still in a building process, they are cheap *** rca cables

but see im running a car computer as my head unit and i think the noise comes from it somehow but before i put the wires thru the dash was not like that soo im guessing the rca are catching noise i got some monster cables rca to test from a friend but i blew a fuse to the computer power supply and then blew the power supply so im in stand by for right now

computer sound cards are not the greatest unless you upgrade to a much better card

i know but i got i nice one off ebay for 30 bucks.

but see the thing is before when i was testing and the computer and wires and everything was outside there was no whine or nothing it was perfect it started when i put it inside the car and run the wires

but im building something like an amp rack and im gonna put the sound card the with the wires separate from each other that was actually my final tough.

but a friend told me i should ground somehow the pc but its a freaking laptop soo i got no idea where ?? do you thing grounding the outside of the rca connectors will help ???

like in some pioneer or kenwood head units i cant remenber right now
