    I have been running a Group 31 agm under the hood with this battery in the back in my 2015 Ford F-150 ecoboost. (With a stock 270 amp alt) All GP 2/0 with single runs to the SMS80 and dual inputs to my Soundqubed Q1-2200. My voltage is steady at 14.7 with hardly any drop. I can’t wait to upgrade to another.

  3. Small foot print

    The size of the battery small but the thing can crank my engine no problem by itself so added with battery under the hood works great for my 2k system Northstar ftw and I would definitely recommend thanks gp for the good costomer service

  4. great battery a must have

    I have ordered now 6 of these batteries and I will be ordering 5more very soon. No not all for me some are for my friends that have system that need stronger batteries. One of my friends was running not extra battery and stock alternator with an alpine m2000. His voltage was dropping to low 11.2 volts!!!!! With just one of these batteries in the rear his voltage doesn’t go below 14.3. If you need a strong battery in a small space this is the only one I will recommend

  5. Northstar FTW

  6. Small

    this battery is so tiny yet handles a lot of power. I'm glad I finally added a trunk battery youd think I added another amp with the increased output

  7. Huge difference

    Posted by JOe on Mar 31st 2017

    I was running a 2,000 watt amp with no battery in the back, this was definitely an affordable way to get louder without buying more amps or changing subs. I'm very happy with the results from this purchase.

  8. awsome
