Make sure my electrical is cool. I think it is.

Setup - 1999 Ford Expedition 5.4L

2 x 15" MTX 9500 1ohm setup

Crunch GP3000D Amp

Electrical:

Big 3 of course - 1/0 Gauge

Stock Alternator - I JUST replaced this thing a month ago, previous alternator crapped out on me.

Question: Will the D3100 battery (second) be enough to handle the electrical? I plan on getting an Optima Yellow up front.

Worse case scenario, I can always just upgrade the alternator. But i'd rather not if I don't have to. I just want a good steady voltage.

I was planning on going with 2 18 BTLs, but found a great deal for 2 15 9500s for only 500 total - so I'm going to jump on it.

Any/all answers are appreciated. Thanks.

Get the biggest you can fit in the front. Or maybe 2 D3100's in the back and leave the stock batt in front.

Check with a dmm to see how low your voltage dips at full boogie. Only way to make sure the electrical is strong enough.
