Car Audio Central - Ultimate Car Audio Forum and Community

The big 3??? Ok I’ve been in car audio about 4 years now and I haven’t heard that expression elaborate? Also about my grounds all of my grounds (3) go to ground distribution block into another distribution block (future 4 more gm-f5100 on the way and two more ts-w2000spls on the way) then ground to body. With cap. So this is how my setup is run power wire (1/0) to distribution block 1 (I have 2 tsunami 1/0 in 4 4ga out) then out of distribution block 1 to 3 amps at the moment wire to second distribution block the 4th out has no fuse so second distribution block has no power at the moment. Ground explained above. Cap is inline. Ill get some pics up soon maybe that will help! How do you post pics? Do you have to have them hosted like other forums? O yea i had this professionaly done by a guy named mick who used to hold the world record in extreme 4+

the big3 is simply upgrading the wiring from your battery, alt , etc.

ok does anyone have a detaitled description or how to on this or point me in the right direction?

I dont think we have an FAQ on the Big 3.

I will right a short one up when I get a few minutes unless someone else beats me to it.

Basicly what it is the basic wiring of the car is not meant to support such current draws/demands.

The wire from the Alternator to the Battery and Negative Post to the Block need to be changed.

These wires are just to small.

BTW its been said/noted by people with extensive knowledge that the car ground is capable to support around 125 amps of current. You will be going over that so you may want to look in running a ground to the front...
