trainman0978 Posted April 26, 2009 Report Share Posted April 26, 2009 Need more info...what kinda vehicle, how big is your alternator, what kinda room do you have for batteries? I would say without knowing anything, replace the factory battery with whatever will fit , maybe a D1200 or D5100 by powermaster, and at least two of the same in the back, or maybe with one D3100 in the back, as well as a battery up front, or something.....it just depends on your alternator..... I would run no less than three good sized batteries on that amp combo.... a new one up front and to in the back, the largest I could fit.... from what I seen around the net, those 3000 s need a good bit of battery support.... good amp, and power hungry to reach its potential. 2007 Toyota FJ Cruiser Voo Doo Blue my upgrades and "build" thread.

tejcurrent Posted April 26, 2009 Report Share Posted April 26, 2009 Depends on how big your alt is, but I'd recommend bare minimum one extra d3100 and a good replacement under the hood. a good factory replacement and 2 3100s would be my choice to keep 14v+. tejcurrent XS Power T3 Link to comment Share on other sites More sharing options...

Just looked I know I have a HO alternator from Iraggi but don't remember exactly which size I told Don the amps I would be using and that it was a 2005 Ford expedition and that's the one he suggested. Batteries could be placed maybe on the drivers side rear behind that panel beside the third row I'll have to take some measurements to see.
