Since it was pretty nice out today I finally got around to installing the extra terminal posts I bought. Now I don't have to pull the subs if I want to change the impedance. It's gonna be a bonus for comps. Maybe this can be an option for you to offer customers that are buying a box for both daily and for comps. If it's nice out tomorrow I'm going to try and meter the box wired down to .5, I really need to make sure the TL works ok on my new laptop, I haven't actually tried it out with on Windows 7 yet.
