small but powerful

I would definitely recommend it if you have a small beginner system in your car taxes power has always been the best even though it is a little pricey you don't get what you pay for

mike r on Oct 25, 2014
i thought you could only have more than one battery if all the batteries where the same size?? (and run in parallel) say i have a 1000 cranking amp under my hood but need some extra boost and don't want to shell out for another 1000 amp battery and want to stick 2 of these in the back, can i do that? or do i have to have an isolator?.. is this xp series of battery not effected by the all batteries needing to be run the same size?.. thanks!

Need help finding a battery because i have 2 alpine swr12s dual 2 ohm with power acoustik gothik 4500 when i play it loud my car lights dim and the dash, I already have a duralast gold about 800 cranking amps need a battery for a second battery that will be mounted in the back?
Ryan D on Nov 1, 2014
Best Answer: Hello Ryan,

Although the XP750 may , in fact, be exactly what the amp needs to run more efficiently, the figures suggest you will need the XS Power XP950 . However, we suggest considering the XS Power D680 , because it is Far more practical, and often cost Less than the XP950 .

Can this battery handle 1000 watts RMS?
Im confused as to what 750 cranking amps means, does that mean 750 watts RMS? or can it actually go above that, because my stock alternator handles around 80 amps so thats about 700-800 watts, and I have a battery under the hood that I assume handles 300-400, so do I need a stronger battery in the trunk or will this suffice?
ant222 on Aug 25, 2014
Best Answer: Hello Anton,

The cranking amps do have a say in the total RMS that you "should/can" run along side it. The "formula" isn't exactly as easy as just 1ca = 1w , but it is a very common 'rule of thumb'. As you can see from the awesome responses our customer have provided, its dramatically varies from setup to setup & car to car . It is, however, safe to say that this kit , as an auxiliary battery, will work well in your 1k RMS project, and will work WAY better than a capacitor (just in case you were wondering).
