I'M installing a jl 300/4 in my 93 F-150. Will only be using the amp to run a set of xr570-cxi coaxials and xr650-csi comps.The headunit is an alpine 9851. Yea, I'm a noo-b at this but I'M learning as I go.Does this sound like a pretty good setup?? Also, Ineed to know what size wire kit I need to buy?the 2 gauge or the 4. Any and all feedback much appreciated. thanks
