Well if you do, check out this video. I install an Eminence 12" Cannabis Rex into a BOSS Katana 50 Watt combo.
Install was easy, really only need a phillips screwdriver and a new stakon 1/4"connector ro replace the 1/8" one. It's a very tight fit ,a little drimmel action on bottom plate of amp would make it cleaner.
