Big 3 on 105 amp alt

[tacomabanga1986]

do u have a stock front battery or any other batteries like 2 or wut knot?

those mtx amps dont pull that much current @2ohm, i had a mtx 500d wired down to 1ohm when i had my 4500's and my old rockford punch he2's n with a stinger 1fcap n 4guage it worked fine

ied just run 0guage to amp n maby a couple runs of 4guage from alt to battery pos n then the regular big 3 grounds n it should be fine

but ya those old mtx amps were pritty efficent with power, or from my experence it was

Just a stock battery and a single run of 4 gauge, waiting for some 1/0 to arrive.

Only electrical upgrade is a batt to chassis in some 2 gauge welding cable.

That little run alone took me from 13.7 to 14.3

Redoing the batt to chassis in true 4 gauge and the alt to batt positive in 4 gauge, one run each, I am now at 14.53-4 volts. Hopefully I will get a second run in on the positive and figure out my engine ground this week.

Just to double check, can I just run the engine ground from the alt case to the chassis if I can't find the stock ground?
