i got the fi bl 12 fully loaded....but i will also be running a 4 channel amp for my infinity comps 5 1/4....will that make any difference

Problably won't need anything, but possibly that bigger battery that he mentioned.

I am doin fine with my SX's and don't dip that much at all with my 2nd battery.

Get another cell and do Big3. Other than that you should be fine.

ok so i am kind of new on the whole electrical subject. when yall mean a bigger battery do yall mean get an extra one or replace my battery that i have in my truck with a bigger one...sorry for the stupid question

Do the big 3 and get a new AMG style starting battery and you should be fine.

[Jakethesnake 0]

Yes, a bigger one under the hood...if that doesn't work like you thought then a second (large Capacity) battery should fix all the dipping in voltage. I know for a fact because I have weak voltage but lots of storage capacity in my rig and never see dipping unless full tilt. I am getting a better alternator some time in the future and then I can crank out more voltage and still have good storage.

I say......

Big 3.......... Battery negative, alternator positive to battery positive, and alternator negative.

Bigger Battery......... Possibly Kinetiks, Power Master, Deka....... the big Group 31's

Also ALL 1/0 power wire though out.

is the big 3 easy to do or no? if its not easy how much would that cost for me to do to my truck?

[Duran 387]

Yes the big 3 is easy, just some 1/0 gauge with terminals is all you need. Add on to your existing charging wires, its just a pain to remove them.

I tend to go overboard with mine, I isolated my front battery and it acts as if it was in my trunk when it is really in my wheel well. I have 1/0 from batt (+) to a (+) post in the engine, batt (-) to a different post in the engine, alt (+) to post (+), post (-) to engine, post (-) to frame, engine (-) to frame (-). So in other words I do the "Big 6"

i had a friend do the big three and he said he did noticed anything different and most people say its a waste of time... but i really dont know if its true... but bigger battery in front (yellow top battery is wht i have) and if ur still gettin v drops then add another cell next to the amp...oo wht ever u do say away from caps...

I have a 04' Taurus with the same 130 alt as your truck (they share parts) and im running a FI bl15 fully loaded on a Elemental designs nine.1 @ about 1400wrms also with a eclipse 400wrms 4ch. at idle their is a bit to be desired but 1000rpm and up its 13.8 volts and higher all the time..all I have is a yellow top and 0 guage for the big 3

[hless421 0]

Yea like in my case, 80A alt. The big 3 won't do much. Hungry amp/sub. But if you have a good alt/batt i can see the benefit.

Time to save up for a yellow top i guess hehe

I'll try to take a pic when I can, I don't know how well you will be able to see anything. My battery is not in my engine compartment and it is a mess of 1/0 gauge.
