abucompu Posted July 11, 2011 Report Share Posted July 11, 2011 Hi guys, I am new to this forum and live in South Africa, I need help and advise, I have the above mentioned battery and it's powering my DD Z1a. I have four runs of 0/1 cable per terminal from the XS Power battery, this battery is the second battery in my vehicle but my primary battery is a 12v. I drive a corsa B (vauxhal). The battery isn't powering the amp efficiently do i need to get another 14v or do i do split charging? Quote Link to comment Share on other sites More sharing options...
speedball1978 Posted July 11, 2011 Report Share Posted July 11, 2011 you need to get an alternator that can charge your d1400 at the correct rate, otherwise your battery is only charging at about 2 volts lower than it should... i needs to be around 15 to 16.5 volts but it also you need to check specs on the amp if it can handle 15 to 16 volts there are alot of scenarios.. the d1400 is a 14 v battery, you should have gone with the d1200 Quote Link to comment Share on other sites More sharing options...
tonedeaf Posted July 11, 2011 Report Share Posted July 11, 2011 (edited) Somehow my post didnt work... Take the battery out. You cant mix 14V batteries and a 12v charging system. You need an alt capable of charging at 16.4V+ to keep from fucking up that battery. Which also means you cant have the 12v battery in the system as well. So you either run nothing but 12v batteries, nothing but 14v batteries+ alt that can charge them correctly, or a separate 12v/14v system, which you would need a dual alt bracket with one battery capable of charging at 16.4+ and one that can charge your 12v battery up front. Not researching before just doing is how people burn down their cars and start fires and shit. Electrical is not something to take lightly. Edit: The system deleted my 1000th post. WHAT THE FAWK.

AA98hoe Posted July 11, 2011 Report Share Posted July 11, 2011 its not goin to wrk like other post said you cant mix voltages 14v requires 16.4-8 to charge properly that will blow up your 12v batt Quote TEAM DC AUDIO VEHICLE:98 chevy tahoe 2wd 3-4 drop HEADUNIT:alpine 9886 PREAMP:arcaudio FRONT STAGE:4-6 1/2s selinium,DD component set and 4-selinium tweeters in each door KICKPANELS:jl audio 5 1/4 REAR DOORS: dd components 6 1/2s HIGHS AMPS:zapco 750.2 on front doors,zapco an another 750.2 on kicks and rear doors SUBS:4-ascendant audio 18s with 5 spiders in a custom box built by KINGSUV SUB AMP: 2-dc7.5s ALTERNATORS: 3-mechmans 1- 425comp, 1-smd spec350, 1-270 with adj voltage harness on custom dc bracket WIRE:10-runs 0g front to back BATTERIES:6-d1400s TL results:157.1 at 38hz and 156.8 at headrest score @37hz.

Nathan @ XSpower Posted July 11, 2011 Report Share Posted July 11, 2011 As has been said. The D1400 needs to be seeing 16V + of charge voltage. Optimal charge voltage is 16.8V. If you are running it off of your 12V alternator, then the battery is basically running as a 12V battery and needs to be charged up properly as soon as you can. You can check with Mechman and see if their adjustable regulator will work with your alternator to charge properly for the 14V system.

Supercharged DCs Posted July 11, 2011 Report Share Posted July 11, 2011 Aside from what everyone's already said, you will also need more than a single D1400 (if you decide to do all that's required to charge it properly) to run that Z1a...
