A very basic formula is that power (watts) equals amperage times voltage.
For example, if you are operating at 120 volts, 580 watts, the amperage would be 4.8 amps (580 divided by 120).

1200 Watt wiring is more than enough for an 800 Watt amp. The rating of the sub doesn't make any difference to the cables. If you want to use the sub to its rated power you should get a bigger amp. If the amp can only give out 800 Watts and the sub can take 1100 Watts then you can put a bigger amp on. It is still going to be loud as with an 800 Watt amp. I have a 300 watt amp with a 1200 Watt sub and people hear me coming.
yes it can
yes
a watt is power, or 1 joules sec= 1 watt an amp is 6.242 × 1018 electrons passing a given point each second,
Yes the amp can push the 2 subs. I have 2 1250 watt 12inch subs and 1 maybe 400 or 500 watt amp and the amp does fine but if you want more bass at lower levels of volume then you want to have a bigger amp. Just make sure your amp doesnt blow your subs.
Yes, are we talking rms or max? If its rms you will have no problem. well the amp is a 1500 watt max but 350wx1 rms in 4 ohm
That depends on the voltage.
The relationship is, a watt is the product of amps x volts.
Voltage times amps equals watts. A watt is sometimes called a volt-amp because one volt times one amp equals one watt.
It's actually a good idea to have a speaker that can handle higher wattage than the amp can produce.
It depends on the rms of the two cvrs combined. Also if the 1200 watt amp is 1200 watt rated (rms) or 1200 watt peak. Lets say the two kickers have an rms of 600 watt each, and the amp is 1200 watt rms, which it probably isnt but i'll pretend. This set up would work because 600 of the amps watts would be correctly matched with one sub, and the other 600 would go to the other sub.
YES! it won't reach it's peak, but that's also probably a good thing, cause it'll be harder to blow your sub. i prefer to buy either the exact watt match for my subs and amp, or buy the next lower watt amp from my subs
