jaelliott9 Posted December 3, 2014 Author Report Share Posted December 3, 2014 so you think i should move my battery back to the back and do 2 runs of 1/0 gauge. i have one already going to the back, and i would need a 250+ amp alt? and hell ya that amp is a beast. i got it wired at 4 ohm right now and im dropping to the 10 volts if i let it. i turned the amp down so my voltage dont drop below 12.4. both amps were set with my DD1. but i need to do something.

Miguels Posted December 3, 2014 Report Share Posted December 3, 2014 he will see more drop with the long runs than if he moves the battery to the rear and use shorter wire.. 14.4 volts on a 17 wire could drop to high 13. on just wire once he plays it will be on the 12's.. in the rear the batter will be around 14.2 but he will start to drop from a higher voltage.. he will benefit by half a volt to even a volt.. he can get away with having the battery bank in the front but will need more runs to offset the resistance in the wire.. 3 runs of 1/0 is what i suggest if he runs CCA or 2 runs if he runs OFC my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
jaelliott9 Posted December 3, 2014 Author Report Share Posted December 3, 2014 the amp is seeing 14.-14.6 depending about how cold it is. but it does drop quick so i will try putting the battery in the back when i get home and see if that will help things out alittle for now.

Rich Schenk Posted December 3, 2014 Report Share Posted December 3, 2014 I would call mike singer and get like a 320-340 amp hairpin alt. I love my 340 hairpin. thing is a beast im going to be running round 6k. And for electrical i have a d3400 up front and 2 d3100s in the back with double 1/0 big 4 and 3 runs of 1/0 to the back.

You're saying that his rear battery will sit at about 14.2 but it won't. He may get a 14.2v reading at that battery with the vehicle running, but not if he disconnects the charge lead coming from the alternator. With the right alternator he is better off not adding a 2nd battery as far as his amps are concerned. A good quality, proper sized cap instead of a 2nd battery would be better in this case. It will benefit him within the 1.8v or so difference between the charging voltage of his alternatorand the resting voltage of the battery.

rockFord_Expedition Posted December 3, 2014 Report Share Posted December 3, 2014 To add some clarity to what im saying, in his current setup with an oem alt and voltage drop into the 10's, a 2nd battery will help him hold closer to 12. Everything I am saying is assuming he goes with a proper alternator to keep things in the 14 volt range.

jaelliott9 Posted December 3, 2014 Author Report Share Posted December 3, 2014 so should i run the back battery straight off the alt or run it to the stock battery? or both? Link to comment Share on other sites More sharing options...
