Big 3 questions - Buy & Sell Car Audio Equipment

I am going to be replacing the big 3 in my truck soon and I was just wondering what a good size of wire is to use. I currently have a 750W RMS amp running off 4 AWG. Thanks for the help.

best to go with 1/0gauge, just in case you want to go bigger in the near future.

1/0 is already good enough.

Because some want to go above & beyond and install 2/0, 3/0, 4/0.

ok great. well just for review (and I'm sure i'm not the only one wondering) what are the 3 cables to be replaced. I can't quite remember the the third one.

If you have spare 4ga a dual run of that vs 1 run of 1/0 ga will be fine.

Actually, you need about 4 runs of 4 gauge to equal one 1/0 gauge. The cross section of 4 gauge wire is about 570 mm^2, while the cross section area of 1/0 is 2,124 mm^2.

Two runs of 4 gauge will get you to about 2 gauge I believe.

I dont believe that, maybe 3, but definetly not 4.
