walmart has a great 4 and 8 ga kit for like 25(4 ga.) and i think like 15(8 ga.). For 250 watts you will be fine with the 8 ga. But you might as well go ahead and get the 4 ga incase you ever decide to upgrade. i first started out with a single 8 ga. then i ran a single 4 ga. Then ran dual 4 ga. Then ran 0ga. now i am runing 2 0 ga. wires to my trunk. Always a great idea to get bigger than what you need in case you want to upgrade down the road. So maybe instead of doing 8 then 4 then someday 0 ga wiring. Start out with the 4 and you won't ahve to waste the money and time to run it a thrid time. But no way should you go ahead and buy the 0 ga right up front.
Stick with the walmart 4 ga wiring kit. Good kit at a great price.
