Ah supply is great. I just got my 2x55w order a few days ago. I'll admit that I had a little trouble at first as the only picture they had was a wiring diagram, so I didn't know what all of the pieces were for. You'll need stuff like: screwdriver, drill, wire cutters/strippers --- takes a little time if you're not too experienced with wiring and such, but even then, it isn't bad. Be careful and don't do what I did -- when drilling pilot holes for the screws, don't accidentally drill the hole all the way through the enclosure (oops). Enjoy!
