ranmansnaple 0 Posted January 20, 2010 (edited) I have a 2003 ford f-150 triton V8. with the stock 130 amp alt. a 0 gauge big three upgrade. i'm running a kicker zx1500.1 at 2 ohms. the birthsheet says 1778 watts, and a sx400.2 at 4 ohms per channel. I'de say all together close to 2000 watts. I want to replace the primary battery with an xs battery. wich one should i get? my guess is the D5100 Edited January 20, 2010 by ranmansnaple 0 Share this post Link to post Share on other sites
Duran 387 Posted January 20, 2010 The largest one that fits. The D3100 is a better battery. 0 Share this post Link to post Share on other sites

Nathan@XSPower 47 Posted January 28, 2010 Actually the D6500 is the direct replacement battery for your application. You will get power for about 3000watts using it as your starting battery. This is a very strong battery and we have gotten great results from it! To get optimal performance from your system I would suggest adding a small secondary battery when you are able to. The D925 or D975 would be a great option or even the smaller D680 would add to the efficiency of the system. 0 Share this post Link to post Share on other sites
