the big 3

[-------]

You may need another battery...if your car truly has a stock 120 amp alt.
I would start with big 3 1st....see if that helps.

i think it is, is the info i got on-line checking for a replacement alt every one of theme say 120 amps thats how i got the info

the battery i allready know that that one is half way dead some time ago (6 or 7 months agor) she died on me i add to use jumper cables but till now she´s been hangging on but i think its time to let it go in peace lol

i will do the big 3 and get a new bat, the biggest that i can feet at the stock location i think is around 100 amps

but damm running 2 ohms its all good but as soon has i change subs and got down to 1 ohm this happens, never cross my mind that running 1 ohm was that big of a diference at the power hope 4 gauge is enough, cuze running a new 2 or 0 gauge is out of my mind now is realy realy expencive and hard to find here

im going to do big 4, but have a doubt, do i need to fuse the new run of wire from alternator to battery or is not needed nd i can run just the wire?

check the dc voltage at 3 places when loaded:

alternator

battery

amplifier

they should be the same. if they are all the same, and still below 11v you need more alternator or battery output. if one section of wire has lower voltage, it needs a better connection or larger wire.

i would put a fuse 6" from battery on the positive wire yes..

A good solid Big Three is a great electrical power base for any powerful auto audio system and should run all the car's electricals great too!

Do us all a favor...don't agree with what we say when troubleshooting for someone because clearly, you know nothing.

I know far more about electricity and magnetism than you do, unless you too are an Electrical Engineer! ;-)
