  1. Can anyone tell me if the T/S parameters on the DC Audio website for the m3 8 (http://dcsoundlab.com/m3-8) for the dual 4 ohm or dual 2 ohm version? ...and before someone says it, YES it does matter D4 vs D2 and YES some of the parameters WILL be different between the 2 versions. The T/S information is not in Term-Lab for the m3 8's and I'm trying to design a box for 4 Dual 4 Ohm m3 8's with very strict requirements to go in a crew cab GMC.
  2. The trim ring is almost 3/4"? Damn. Now I'm REALLY curious about the max height of the excursion after seeing the Frozen demo song played on the M3 8's on WCA Rusty's Youtube channel...
  3. I'm looking to build a box like WCA Rusty's in a 2019 Silverado Crew Cab (4 DC M3 8's ported). However, I want to build a cover in front of the subs to protect them from feet. I'm thinking 1-2 layers of 18mm (3/4") MDF with a pressed metal grill in front of each woofer, but I need some information before I can move forward. Does anyone know what the distance is from the mounting surface on the box to the maximum capable excursion of the cone? Or at least the height from the mounting surface to the top of the surround while not powered? (I can figure out the rest of the distance using the Xmax) If the distance is too much I'll have to drop down to ordering 3 subs to reduce the depth of the box and I don't want to ruin the subs by having them hit a metal grill and cut up the surrounds, or worse.
