I am in the process of planning the intall on the 011 WRX hatch, I am using a Alpine PDX 4.100 amp and wanted to know what speaker wire gauge I should use. I have to run wire through the doors etc. Was pondering using the stock wiriring 18-gauge with the Metra installation bay all in one 18 gauge Quick wiring kit that houses all the wires in one cable, was gonna run the amp wries back to the original stock wiring and use the stock wiring this way i do not have to rewire the doors.

Wil this be a problem for 100 watts throug a stock 18-gauge wire? Plwase help!!
