Help with Diamond Audio

Hey guys, I'm back after a long absence. Recently made a big jump and opened a shop outside Toronto, and obviously I'm now trying to make my car into an sq demo car.

last time I was active I was talking to a Diamond rep who sold me a pair of D971 components, I've since installed those in my car, but I want to get more out of them. trying to find a manual for these speakers to no avail, so I'm wondering if anybody here can give me a hand? Diamonds website is garbage and I've emailed them twice with no response, so any help would be very much appreciated!

I know there's a lot of industry people here, so if you're with the company, are a sales rep, or even carry the stuff I would be grateful if you can even point me in the correct direction. Thanks guys!
