bcbrassard Posted April 1, 2018 Report Share Posted April 1, 2018 What is the stock alt's output? Are you running a mids & High amp? Link to comment Share on other sites More sharing options...

bcbrassard Posted April 1, 2018 Report Share Posted April 1, 2018 There are wattage to amperage calculators you can google. Stock alt and upgraded battery your possible maxed out on your electrical and if you plan a mids & highs amp down the road another battery wouldn't hurt. What ohm load and wattage will the amp be putting out? Link to comment Share on other sites More sharing options...

guero187 Posted April 1, 2018 Author Report Share Posted April 1, 2018 1 ohm not sure the wattage. so if just went ahead and bought a ho alt and went with that would it still be recommended in getting a 2nd battery? Link to comment Share on other sites More sharing options...
bcbrassard Posted April 1, 2018 Report Share Posted April 1, 2018 SUNDOWN website rates that amp @ 3000 watts in 1 ohm. Link to comment Share on other sites More sharing options...
bcbrassard Posted April 1, 2018 Report Share Posted April 1, 2018 I am not sure if i am using the calculator right but it comes up at 200+ amps at 3000 watts in 1 ohm. Link to comment Share on other sites More sharing options...
bcbrassard Posted April 1, 2018 Report Share Posted April 1, 2018 XS D3400 looks to be good from 2500-4000 watts. From what there website shows. Link to comment Share on other sites More sharing options...
bcbrassard Posted April 1, 2018 Report Share Posted April 1, 2018 I think your stock alt would have a tough time keeping the battery charged. I would looking into a alt upgrade and second battery for future upgrades. I am not the most knowledgeable person on this website and others with more experience will chime in. What i do know is the electrical is the heart of the system and hard to go overkill in my opinion. I run a little over 3500 watts total and have upgraded alt and 4 battery's. I just didn't want to half ass it so i know doing it right the first time pays dividends and protects the equipment. I have about 2 grand into my electrical. So i know it's not cheap but is done right. Link to comment Share on other sites More sharing options...
