I am sure that off 1200rms fused accordingly that the Raptor stuff will be just fine, since you have all the other stuff already to save monies for now, unless you dont care. If you didnt though, I dont see why you would be buying cheap wire.
It does **** to see how small it is and much rubber is covering that ish.....indeed false advertisement. Lesson learned, we have all been there a time or two.
Good luck on install.
By the way, I am partial to Knu...even their cheap brand works really well. Also like Tsunami, but you dont see them around much anymore. Running it in my car with Knu currently though.
