99 expedition meets MTX Thunder

[beast2040]

I'm upgrading from 2 mtx 12's running at 600watts combined power with no added power supply to 4 MTX T7510-44 10" 1600w DVC CAR SUBWOOFERS SUBS that run at 400w rms at 4ohms. They will be powered by 2 MTX AUDIO 1000XD MONO BLOCK 2000W AMP CAR AMPLIFIER running at 700w rms at 4ohms. My 1 and only concern is power. There seems to be a decent amount of debate over dual batteries vs H/O alternator. When running 1400w rms what would be the best bet. 2 optima yellowtops or 1 optima yellowtop and a new alternator.

2 optimas

you probably arent pulling near enough amperage to need a H/O alt.

for daily, IMO i wouldnt get a H/O alt until your over 2,000rms

x2 I've got a 2001 Expedition and they've got a pretty darn good stock alternator in them. You may even want to try it with just an Optima under the hood and see how it holds up.

Yep, beefy factory alty. I would do what bobby says and try one under the hood and if need be, then get a 2nd one.

i agree with the rest of the responses. i run 1500 rms in my s10 though, and i do need an HO alt., mostly because i run a ppi pc2350 for subs, which is a class a/b amp. it pulls a buttload of power.

When i had 2200w in my Expedition, i only had a D3100 up front, Big 3, and a OEM alt. Had to step up when i put some power in it though.
