I'd love to have those Mac amps in my system. I've got a MC402 running Piega C10 Ltds. They need a little more juice but sound insane as is. 1000 watts each would be ideal.
I got the sign from a company in Missouri by the name of Grove Engravers. If they dont already have a template, you can send an image of what you would like the sign to look like, and Joe will custom make it for you. Nothing fancy, just an LED light base with the plastic sign inserted for illumination.
