Here is my build. Started life in 07 then grew. I officially scored 145.6 at 37hz sealed on the dash. Let pics speak for themselves.

optima yellow tops are alittle more wallet friendly but id get 2 of them with optimas you dont want to mix "off brand" batteries so get one for front and one for back. but like everyone else is saying get a D3100. the price of one of them is the price of 2 optimas.
