No more voltage drops!!
I normally do not write reviews but I just had to for this item. This battery has completely stopped my voltage drops. I have 3 amps, a mono block, a 2 channel, and a 4 channel amp. 1000 rms 1 channel, 80x2 2 channel, and 50x4 channel. My car which is an 2003 Nissan Altima has a 110 amp Alternator. I am running about 1300+ rms watts and previously, my voltage would drop to 11.8 on my hardest hitting song. After upgrading the big 3 and installing this battery, my voltage does not drop below 14 at idle. I highly recommend this product if you are running anywhere between 1000-2000 rms and you are experiencing voltage drop.

XP Power XP950
I use this battery as the first battery in my wifes 1997 Honda Civic Si and was told by XP Power not to use it as a first battery, it works amazingly its as great as the XP Power XP3000 I have in my 1987 IROC-Z 5.7.

all u need for hours of fun
Well I do alot of sitting around at softball games with 2 hours in between some games and this battery is no joke with amps on, inverter, tvs and ps3. It runs it all for hours I use battery isolater so all that runs strictly off my XS battery.

So far so good
I got this product, to add extra punch to my sound system. it has done a great job, creating less strain on my alternator. keeping my headlights from dimming, while adding continuous power to my amp.

Great product. Puts out the power your system needs
Great battery, puts out the power you need, got it on a 1200 watt setup. No dimming lights and the car have more current. My voltage does not go below 13 volts when playing music. Get a battery isolator for your setup

It's a beast
Not big as the ones the guys on youtube get, but it holds its own against some pretty serious bass... very recommended. Had it on a 1600w cab amp with no electrical issues or dimming lights...
