Caps, were a big thing when they came out but all they do is take soem of the stain off the battery but it still have to charge up quickly for when the bass hits again so it is not really doing much of anything to help your electrical system. They help give the amp extra juice yes but they harm your electrical system because they suck juice quickly from your main battery and put strain on your alternator. Better not to have hem. Plenty of threads about this over at caraudio.com seriously plenty.
If you need something like this than you need to upgrade your grounding points "the big three" Ground wire from the battery to ground ground to engine block and there is another one I can not think of right now. Alo adding a small extra battery helps as well much more than any cap would.
A lot of shops will try to sell you caps and promise you this and that about what they do. No reason to get them and z's stock electrical system is pretty good at taking a good power demand.
