Antoni Čović Posted July 4, 2018 Report Share Posted July 4, 2018 First or second option for best perfomance? Right now I have 2x 55AH wet batteries and on 3kw amp on full tilt I get to 11.9-12.1v on amp.. Will any of this options help or it's wasted money?

Big 3 done... all wires are 0 gauge. I'd say an alternator that's around 40% bigger would be worth it. That 105 amp will charge 2 decent size batteries a lot better than that 75 amp imo. Any REAL 3K amp is going to need bigger than a 75 amp alt for certain. More like that 105 amp and at least 150-180ah of juice. Again jmo Link to comment Share on other sites More sharing options...
alex912005 Posted July 9, 2018 Report Share Posted July 9, 2018 The best way to make a noticeable improvement would be to add another subwoofer. Even on the same power, 2 subs are a lot louder than 1, if you have the space. Even if you get a +0.5 or 1 V improvement in voltage, it won't be much louder. The money for batteries is best spent on a second sub. Cone area is king. My Build Log Link to comment Share on other sites More sharing options...
