well 2 are 16 volts and the others are 25 volts
ill see if i gots some 10 volt ones

BTW they make a nice mess when they explode!

10 volts will work fine most times, thought they will be a bit border line with 7 cells
I use 16v ones Myself

You never put powercaps across the speaker wires (hey, its also coil + magnet & it moves...!), but if you don't run crossovers between tweeter and woofer then putting signal caps can do some basic filtering for you.

Depends where you hang out I guess. The fellas that deal in stealth instos into german wheels still use "ICE" quite a bit... ICE would mean a totally different thing to the doofdoof crowd tho!!
I've never had ANY experience with lag in response time with large caps... all quality caps start discharging within 1000ths of a second after the power supply is removed... otherwise their purpose in a car audio install is pointless... caps are meant to provide the instant power required by the amplifier to reproduce transient peaks in the music (usually bass related but not always) so unless their response was instant they would be a pointless addition
In the early days (say late 80s) the boys were just starting to use caps. We would search around for large caps from used industrial equipment, these were the real deal. Roughly speaking 0.5F ones (size of a coffee mug) weighed about 1kg...

The voltage marked on a cap is the MAX operating voltage.
A 25V job will work identical to a 16V item if your operating voltage never exceeded 16V... but the 25V cap is usually dearer (by only a few cents) and may be physically larger.
The high-voltage ones like 250V or 400V are usually for mains filtering and are designed for AC voltage. Non-polarised caps are more expensive too.

mate i have so many caps its not funny
i got one the size of a D cell battery i got a couple of 10 volt ones
and your right the 25v one is considerably larger and i was thinking they would work the same even tho the voltage rating is different
