Great battery.. but not the most powerful ever... Look at DC Sound Labs batteries. They don't sell them here.
i purchased this battery to replace my yellow top optima battery and let me tell ya something- what a difference!! my bass got deeper, my H. I.D got brighter, you cant go wrong with this battery!! but before purchasing make sure it fits under your hood!! i have a 04 navigator and i had to make some minor adjustments!! so do the research prior to purchasing!
I have an Optima yellow top under the hood and two of these in my trunk to power ~3.5kw. Although they are rather large, they surely do the trick. Little to no dimming at all and voltage stays high.
2 of these is getting me over 154 db!
this battery is a beast, specially if you have subs pushing 1000 watts or more, i have 2 of these pushin 4)cvx kickers and a kicker 2500.1 and 2 other amps for my highs, and that shit knocks, volts stays at 14.2 drops to 13.6 sometimes.. this battery is KING!
Monster power cell to help keep your voltage up when running your system full tilt. Got 2 of these bad mofos.
