Are you looking to upgrade to a bigger system any time soon or are you planning on staying around 2000watts for a while? I only ask because it doesn't make sense to spend money on something now, that you will need to upgrade in the future. Quote Link to comment Share on other sites More sharing options...

Nightshade Posted January 10, 2010 Report Share Posted January 10, 2010 (edited) have good room in back, its a suv,and i dont plan on going past the 2500 mark What suv is this that you have? The reason I ask is you may be able to fit a D3100 where the battery that you have now is at and that would work well enough as a primary battery on 2500 watts. On top of running a D3100 I would reccomend at least a run of 0 guage to your amp for power and a run of 0 for negative as well. Then there's always the thought of adding a high output alt and can be done down the road when you can either afford it or decide that you would like to keep nice 14 volts while playing full tilt on music.

matt402 Posted January 11, 2010 Report Share Posted January 11, 2010 i think just adding a d1200 would be enuff. Quote Link to comment Share on other sites More sharing options...
Nathan @ XSpower Posted January 11, 2010 Report Share Posted January 11, 2010 A D1200 would do you good as a secondary battery. Quote Link to comment Share on other sites More sharing options...
