That depends on the voltage.
700 watt is 0.93871 horespower
There is no volt meter or amp meter in a DC watt meter.
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.
800 watt should be fine
About 1/2 amp.
Yes, a 1200 watt amp can power a 300 watt box. The wattage of the amp refers to its maximum power output, so it can deliver up to 1200 watts if needed. As long as the amp is set up properly and not pushed to its maximum capacity, it can safely power a 300 watt box.
50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.
you just need one, a general rule of thumb is that the wattage on your amp should be double the wattegae on your sub, hence if you have a 1200 watt sub you'll need a 2400 watt amp
about 4800 watt but should not use it 100% so to be safe 4000 watt (80%)
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.
