some people will tell you to upgrade the BIG 3. it inst needed unless you have a high power system. as for cables... i do say use 4ga @ the battery location. as for your amps... you might want a dist. block and switch to 8ga all pending what ga your amps can take.

as for a sub box, i like sealed boxes. make sure it's built to spec on the 10w7 for best preformance. hope this helps ya a bit.
