PaulPumpsBass Posted July 27, 2013 Report Share Posted July 27, 2013 I am looking at adding an additional battery to my current setup, which is only slightly over 5,000w RMS. My setup as it currently stands: 1 - 250amp H.O. Alternator (full 250amp output @ 1,200rpm) 2 - Optima Red Top Batteries under the hood (dual battery kit) 1 - 12 Farad Audiobahn Capacitor 1 - Metra Electronics Install Bay IB-200 (200amp Battery Isolator or Relay) I am just looking to get the full power out of my amps, not sure if I'd even need another battery in the rear with the amps. Because I don't know what the requirement thresholds are (ie. watts/amps/volts) to require an additional battery back by the amps. Space is limited, and I want to avoid removing the third row seat, so a small yet effective battery (or batcap) would be great. Just looking for your thoughts. Thank you in advance to all the experts/techs/installers/enthusiasts!

Pioneerchuck Posted July 28, 2013 Report Share Posted July 28, 2013 What amps are you running and at what ohm loads? Quote Link to comment Share on other sites More sharing options...
CJ18 Posted July 29, 2013 Report Share Posted July 29, 2013 If you are running a true 5k amp, i would go with 2 D3100s or 1 d7500 Quote Link to comment Share on other sites More sharing options...

Nathan @ XSpower Posted July 29, 2013 Report Share Posted July 29, 2013 What is your voltage doing now? Do you play for long periods with the car off? Quote Link to comment Share on other sites More sharing options...
PaulPumpsBass Posted July 30, 2013 Author Report Share Posted July 30, 2013 (edited) Sorry... I'm in Afghanistan. I have to email back home for this info. I would wait until I got home, but I want it up and running at full power by the time I come home for R&R late next month. I have 2 of these Optima Red Tops under the hood. http://www.optimabatteries.com/us/en/shop/redtop/optima-batteries-8004-003-34-78-redtop-starting-battery/ If I replace these 2 with larger (because I have more room in the locations under the hood where these currently sit) batteries, would that be enough extra amperage? I was thinking of going with 2 XS Power batteries, but I'd want side and top mount posts, as my batteries currently have it that way and I'm using both posts. I looked on XS Powers site, and couldn't find any with side and top mount posts, do you offer any? Would the XS Power batteries with the extra amperage negatively effect any of my stock ECU or anything else? (sorry, I'm a novice, asking questions trying to learn).

PaulPumpsBass Posted August 2, 2013 Author Report Share Posted August 2, 2013 Ok... I had my sister check it. When the stereo is on without the car running, it is at about 9.6v. When the car is started, it is between 13.1v-13.8v depending on the song playing.

PaulPumpsBass Posted August 20, 2013 Author Report Share Posted August 20, 2013 What is your voltage doing now? Do you play for long periods with the car off? Ok... I had my sister check it. Apparently my Dad stole my second battery for his mini-van, because I'm in Afghanistan until next month and no one is driving my Yukon until I'm home for R&R for a few weeks next month. When the stereo is on without the car running, it is at about 9.6v. When the car is started, it is between 13.1v-13.8v depending on the song playing. I don't play the stereo with the car off for longer than about 10-15 minutes if I'm waiting for somebody to pick up something in a store, or make a bank withdraw. If I expect them to be longer than that... I'll usually go in with them.

Nathan @ XSpower Posted August 29, 2013 Report Share Posted August 29, 2013 OK then get the cap and isolator out of there and sell them if you can. Then put two S3400 under the hood in place of the optimas and call it a day. Quote Link to comment Share on other sites More sharing options...
