Default Upgrading to 1/0 Gauge wiring in engine

This may seem a bit unorthodox but I thought I would post what I plan on doing to my engine in my 06 5.7 HEMI engine.

Basically this is the deal: I put in a ~2400w sound system a while ago, and they put a 1/0 gauge lead on my battery to power my amps. Mind you I only have 2x Boston G2 10" subs, but when they hit when my volume is @ about 1/3 cap, all my interior lights and headlights dim.

This is actually kinda badass in my opinion but i want to fix it.


So what i was planning on doing was this:

Replace the wire from the alternator to the battery + with 0 gauge
Replace the wire from the fuse box to the battery + with 0 gauge
Also, Replace both the battery grounds from the battery - to the engine block and the chassis.

A friend of mine did this to his '02 silverado after he put in a 1000w power inverter that when used caused the same problem i was having. His mod fixed the problem.


My theory is that if i switch out the stock 8 gauge wire from the alt to the battery, to a 0 gauge wire, that i would get more raw energy throughput to my battery and help prevent those energy spikes from my subs that are effecting my lighting.

I know this sounds a little nuts, but other than this the only solution I have is upgrade my Alternator, and that's way more expensive. Right now i have the stock alt (which is ~130 amps if i'm right)

Pictures are attached, the large blue wire is my 0 gauge speaker lead

Fuse Box pic, replacing the red wire in the picture with 0 gauge from battery + to fuse box +

Any feedback would be awsome, thanks!
