i have an 700 watt amp that puts out 60 watts RMS x 4 i want to add a 700 watt sub-woofer amp puts out 200 watts RMS x 1 and i have a 8 gauge wire already installed can i buy a power distributer or do i have to replace my 8 gauge with a 4 gauge? any other options?
 
In my opinion... Bigger is almost always better, when it comes to your cabling.

However, You should be fine with what you have. I believe that 8 gauge cable can handle a continuous load of around 50 amperes. Those 2 amps will draw nowhere near that kind of current.
