  1. bye bye voltage drop

    Posted by Justin Whitman on Feb 21st 2018

    This battery is a beast. I have 2 fi audio sp4v2 15 with a soundqubed 4500 wired at 0.5 ohms. Before I got this battery my voltage was dropping to the low 12s with just one agm80. Now it stays above 13.5 at full tilt and I haven't even had a chance to put my H/O alt in yet, so I'm very satisfied with this beast. Don't think twice, just get it. It's worth the $$$

  4. 2 Northstar agm 31s

  5. back to agm from lithium

    Posted by Unknown on Oct 23rd 2017

    I ordered a northstar group 31. Used to run northstar then jumped on the lithium train, was running a 20ah on 4,000 watts. The lithium was obviously spent in less than a year as the voltage just continued to get worse and worse, and was never that great to start with, took out the lithium and put the 31 in, No comparison, the 31 hands down kicks that lithiums ass.


  6. Great battery

    Posted by Mike on May 2nd 2017

    I just ordered my second one of these and loving it. Staying about 13v on a DC 9k with a Mechman 240 also. I will be ordering more of these same batteries in the future for other car audio builds


  7. Fast shipping

    Posted by Steven Bass on Mar 30th 2017

    I ordered my new AGM31 at 1 oclock on a Monday, I got a tracking update 5 minutes after placed my order, and showed it was on a truck 1 hour later. I'm in a surrounding state from where it shipped from, and received it the next day. *Applaud* Thanks GP will be back for more!


  8. Best attery available in it's class

    Posted by Unknown on Dec 18th 2016

    I couldn't be happier! GP Car Audio has been the best in all aspects! Availability, Reliability, Friendly Communication, Proper Customer Service, Order processing, and Shipping was lightning fast.

    As for the Battery...It's North Star! Nuff said! And the warranty through GP and North Star is no BS!

  10. This battery is no Joke!

    Posted by NYCARAUDIO on Jun 23rd 2015

    Bypasses the xs power d3100. This battery is not a joke. By far one of the best batteries I have owned in car audio. (if not the best) Have 2 of these hooked up together. Voltage stays at 13+ with the bass thumping at it's hardest.
