DUBIE Posted October 20, 2009 Report Share Posted October 20, 2009 (edited) just add a second batt and do the BIG 3 and you will be fine.. it is only necesary to upgrade an alt when your running 3-4k+ rms...or when you have major dimming issues Edited October 20, 2009 by DUBIE Quote Link to comment Share on other sites More sharing options...

Torres Posted October 20, 2009 Report Share Posted October 20, 2009 it is only necesary to upgrade an alt when your running 3-4k+ rms...or when you have major dimming issues ummm no i'd upgrade my alt with anything more than 1000 watts. *some* cars, depending on how big the stock alt is could last you up to 1500 or so. but in your case i'd just replace the main battery with a good big performance battery and you should be ok Quote Link to comment Share on other sites More sharing options...

enemyofsilence Posted October 20, 2009 Report Share Posted October 20, 2009 (edited) your stock alt will strain with ~1000w. i know its not recommended but it should be ok with the big 3 and extra batts... edit: like expo said ^ with just replacing the main batt with the biggest batt you can fit would work.

LoudBimmer Posted October 20, 2009 Author Report Share Posted October 20, 2009 i just watched EXOcontralto video on how to upgrade it, but i didnt get the part with negative side. so i will need 2 wire going from negative side, one to ground and other one to "- Engine block to ground" what's the engine block?

enemyofsilence Posted October 20, 2009 Report Share Posted October 20, 2009 the engine block is your actual car engine. so you have to look for a bolt on your engine that you can take off that is safe and ground it to the chassis of your car.
