Lol, that's a tough one.. As you're left with roughly the same amount of capacity in the end.

Hmm, which would look better in your install? I say do the 4 Stingers. I can't comment on the performance difference, as I have experience with the SPV70s, but not the Dekas.

I only have heard good things about them.

Thanks for the input! Yes they have the same capacity but the SP70's look a little nicer. Not that i really care but anyways... I was also wondering on the internal resistance and so on. Anyone have experience on both? I got 10 views and no votes?!?

Internal resistance wise, I can almost guarantee the SPV70s have less, it is just inherent in it's design. Different chemistry for different apps. The Dekas are supposed to be big ol' deep cycle abuse taking muthas. Meant for discharging at relatively high current for longer periods of time. While the Stingers, are supposed to act like "power cells" for quicker response, you know, the same concept as to remedy one's light dimming issues and such.

And, HELL NO, I am not comparing capacitors to proper mobile audio batteries.. In case someone got that image.

I think you'll get more performance out of the Stingers IMO.

They are meant to discharge more quickly than the Dekas, but cannot readily give the amount of current the Dekas can, however, that will be made up for by using four of them.

Ok, thanks for your input!

Anyone have proof of this?
