So I have been using undersized wire in my vehicle for a few years. I got lazy when I got a new car and had an in-store credit from Best Buy so I allowed them to install my wires. Big Mistake.
I'm running an Audiobahn A8000T (RMS: 800w x 1 @ 2 ohms, 400w x 1 @ 4 ohms) running a 2 ohm load. So the Best Buy "professional" decided to run 8 gauge for the whole thing despite the fact I asked for 4 gauge. I haven't had any problems really (noticeable) but I know this eventually needs to be addressed. The problem is I don't want to run 4 gauge from my battery to the trunk because I want to upgrade to an SAZ-1500d. The amp I currently use can't accept 0 gauge, and I don't want to buy 4 gauge and run it for only a temporary setup; so I'm kinda stuck with the 8 gauge from battery to trunk for now.
However, I have about 12-15 of my old Rockford Fosgate 4 gauge sitting around. It is not long enough to run from my battery to the trunk, however, there is plenty to replace all the other 8 gauge wiring.
Quick overview:
Amp: 800w x 1 @ 2 ohms
8 gauge wires:
A. battery ---> capacitor
B. capacitor ---> amp
C. capacitor ---> ground
D. amp ----> ground
Would there be any advantage to replacing B, C, and D with 4 gauge or is it irrelevant since the main power wire (A) is 8 gauge?
I'm going to be doing a lot of work on my electrical this fall as I slowly prepare for an upgrade. However, having this 4 gauge sitting around I'd be happy to put it to use if there is anything to be gained.
As always, mad respect Car Audio Wizards.
