Shurikens are great

The Shuriken SKBT-75 is a great battery.
I am running two for aux and one SKBT-60 for the starter and they work great together.
I run two Soundqubed hds310's on a AQ2200 and a AQ120.4 on my mids and highs.
Over all, I like those AGM's and would highly recommend.
XS Powers are great but the Shurikens are nice price wise.

Killer power

Great power sits at 13 volts when off jumps to 15 in my truck with alternator
