Re: 2001 SH all new stereo wiring

and to make it nice n easy-- See the links in my signature.

Ground in the automotive environment refers to the V- (=voltage) negative / likewise this is the (-) post on your Battery.

signal wire and speaker wire are two completely different wires
*Signal typically refers to the low voltage "RCA" cables that provide signal to the amplifiers, crossovers, etc. RCA's have the round connectors with the center pin.
IF you have induced noise, alternator whine, buzzing, etc. it is MOST often due to an internal 'grounding' issue--not normally caused by running the cable next to the power wires. It would have to be an extremely hi amperage line and/or really crappy, non-shielded, RCA cables to allow this kind of noise in.
Speaker wire typically refers to the stranded pairs of wire that provide the AC "hi powered" signal from the amp to the speakers. It is 0.0000009% likely you will ever hear any induced noise by running these wires to next to the B+/V+ wires.

Lastly, 8AWG is a bit overkill for 400W 6x9 inducers (I hesitate to call them speakers--don't ask why, you wont like the answer. LOL!)
Save yourself some money and just run 12AWG to the rear deck speakers.
Now, if you are running thousands of watts to a pair, or more, of subwoofers, then yes, 8AWG may be appropriate. I have a chart here somewhere that shows you what each AWG wire can handle and up to how many feet it is sufficient.


*Fly's away*
