2 12's at 1 ohm from a Crunch PZi 1600.1D, probably getting 500rms a piece or a little better.
In comparison, when I was working for a local and respectable audioshop, the manager had 2 15" Memphis (quick edit:) M-class with a Clarion 3000D on both of them in a Civic, and my setup is a little louder but doesn't hit as low, which I'm not too happy with, but I'll live. (His are in a sealed box with about 2.4cu.ft. each and it shakes stuff up!)
Any comments are cool, just figured some of you guys may remember the MD Sw's. Mine aren't POS's, but I would like to upgrade some day, cuz I'm giving these a lot and not caring, lol.
