Dezzy FN Baybee Posted July 11, 2011 Report Share Posted July 11, 2011 I just got my XX Maxximus (NOT the XXV model). I have a car so I can't run multiple alternators and what not. I wanted to do either XS Power 14v batteries or 16v batteries to get it to its full potential. Has anyone run these batteries or should I just stick with 12v batteries and 1 220 amp mechman alternator.

finkster Posted July 11, 2011 Report Share Posted July 11, 2011 Are you planning on running a 16 volt alternator and then running a step down module? Quote DAT 4125------>RE XXX comps active Eclipse cd7000 I serve drunks for a living Link to comment Share on other sites More sharing options...
bumonskateboard6 Posted July 11, 2011 Report Share Posted July 11, 2011 14v batteries charge at 16v and 16v batteries charge at 18v. I'd say stick with the upgraded alt and stick with the 12v XS Power line for your batteries.

Low voltage doesn't blow amps. That's a myth. A router that does the sub holes makes rounded edges also? Link to comment Share on other sites More sharing options...
Dezzy FN Baybee Posted July 11, 2011 Author Report Share Posted July 11, 2011 Are you planning on running a 16 volt alternator and then running a step down module? No I was just going to run the batteries together in the trunk. 6 or 7 batteries directly to the amp Quote 2005 Hyundai Elantra 2 DD 3518s Hifonics XX Maxximus 150.5 @ 57Hz Legal 153.5 Kick Link to comment Share on other sites More sharing options...
finkster Posted July 11, 2011 Report Share Posted July 11, 2011 You have to charge the batteries at a higher voltage. Or else it would be the batteries charging the alternator LOL. Just stick with a bunch of 12v xs batteries and a beefy alt to keep them charged.

I don't play my system for hours on end I hardly ever play it unless i'm on the meter or someone wants to temporarily deafen themselves.

finkster Posted July 11, 2011 Report Share Posted July 11, 2011 (edited) Some competitors do that and then charge it later. Thats fine if you arent giving long demos. But why not just go with 12 volts and run more batteries and still have a solid electrical? are you burping only?

But why not just go with 12 volts and run more batteries and still have a solid electrical? are you burping only? well I have been doing demos when I had my crappy Power Acoustik 5500. I had a kinetik 2000 wired to my starting battery and a 20 fared cap. But I paid all this money on a amp and I just want to get all of what i paid for. I really want to put up some numbers so I was looking to try 14v or 16v batteries Edited July 11, 2011 by Dezzy FN Baybee Quote 2005 Hyundai Elantra 2 DD 3518s Hifonics XX Maxximus 150.5 @ 57Hz Legal 153.5 Kick Link to comment Share on other sites More sharing options...

No I was just going to run the batteries together in the trunk. 6 or 7 batteries directly to the amp Do us all a favor, and stick with 12V... If you get 16V batteries, and don't get some sort of external regulator, you'll fuck them up. If you do run an external regulator, and think your car will be fine, you'll fuck it up... Best advice I can give you is to READ... Read lots of stuff... Its all right here... Learn and then make your decision... thanks. I just wanted some opinions. the previous owner said it would take 16v all day long in those exact words. But mike from maxxsonics said its not 16v stable. what about the 14v batteries? still too risky?

gally Posted July 11, 2011 Report Share Posted July 11, 2011 why would you run 12V amps that are rated at 14.4(most of em) to 16V battery which charges at 18volts?? thad would be a suicide to me....i mean for the amps Quote 2010 Chevrolet Cruze Radio --- pioneer mvh-200vbt Front/back --- alpine type s 6.5" Sub Control --- Pac LC1 Sub Amp --- GZPA 1.4K Sub --- GZNW 15XSPL D1 Battery - GZBP 12.2500X Link to comment Share on other sites More sharing options...
