kryptonite Posted January 1, 2014 Report Share Posted January 1, 2014 ahright so, gonna run a pair of 5ks on my 18s and before i get too deep into it I need to figure out my battery situation. I am going to be running a pair of gm large case alternators from Mike Singer. They will be dedicated to the system and thats all they'll be powering. I figure 3 d7500s would be sufficient to keep the amps happy as a daily ground pounder at full tilt 90% of the time if i were to run 12v. OR should i run 16v and how many of what XSPower battery should i get? I can't say i'm staying cost efficient because of the sub and amp selection lol What's my best bet??

corona_jeff Posted January 1, 2014 Report Share Posted January 1, 2014 I'd suggest 8 min d1600s for a pair of 5ks Quote Link to comment Share on other sites More sharing options...
kryptonite Posted January 1, 2014 Author Report Share Posted January 1, 2014 would you suggest going the 16v route though?

Borris The Blade Posted January 1, 2014 Report Share Posted January 1, 2014 Those are 16v bats. Quote It's like rubbing your wiener up against a sheep. Link to comment Share on other sites More sharing options...
kryptonite Posted January 1, 2014 Author Report Share Posted January 1, 2014 i know, but my initial question was is it worth it to run 16v for the amps? I'm looking at the specs on the droppin hz website and if i had 4 7500s vs. 10 1600s, the 7500s edge out by a little bit on weight, ah, rc and cost. Most would think thats better but for those of you who run 16v and had ran 12v previously, which would you go with?

tacomaguy1 Posted January 1, 2014 Report Share Posted January 1, 2014 The 2 alts running the 16v with a stock for the rest is the way to do it, no stepdown modules to mess with. Idk I always hear a lot more problems with 16v vs 12v setups. Either way would work and be good really Quote Team Flex Issues Link to comment Share on other sites More sharing options...
CJ18 Posted January 1, 2014 Report Share Posted January 1, 2014 I would stick with 12v for daily. I just swapped back to 12v from 14v. With the 12v batteries you get more reserve capacity and you can use all of your alternators to charge the one bank instead of having to run 2 charging systems. If you were competing and looking for every last watt that you could squeeze out of amps, then 16v may be worth it, but of you are looking for a reliable daily driver, just stick with 12v. With dual 350s and 2 5ks, I would run 3-4 d7500s. Yes I know it is overkill, but you want to keep your voltage as close to 14v as possible.

CJ18 Posted January 1, 2014 Report Share Posted January 1, 2014 Just to give you an use on power from the 5k. It dynoed right around 4kw at 11.6v and 1 ohm. Got 5500w+ at 14v and 1 ohm. Wire em down and let em work. Quote Link to comment Share on other sites More sharing options...
SnowDrifter Posted January 1, 2014 Report Share Posted January 1, 2014 I'm running 14v, charging at 16v right now. Love it. I'd say run 16v (or maybe 18v?) if you can.

kryptonite Posted January 1, 2014 Author Report Share Posted January 1, 2014 I'm a strong believer in overkill lol Amps will be run at 1 ohm for now until i'm out of warranty and i'm sure of my volume control, i get "full tilt happy" and blow crap up lol. Once i get comfortable with how things are running i may wire down to .5 or get bigger amps (most likely bigger amps). I guess once i get closer to building time i'll make the final decision, seems even so far comparing specs to individual experiences. Looks like i'll be in either a Tahoe or Escalade build wise, found a caddy somewhat local in good shape getting details as I type this lol. Want to keep second row of seats for sure so space is kinda limited. May do what steve did in the 'hoe and drop the spare tire in favor of a battery rack, mine would be fully sealed up though since Buffalo weather sucks lol.
