I just got 2 brand new Mach 5 MJ-18"s 4 ohm versions. I realized im going to have more power on tap then i thought..so i can get somethin with a lil more power handling. looking for 2 18"s to trade for mine+cash on my part most likely. need to be in good shape. i have 12.5 cu ft for both of them. I can get pics of my MJ's when they arrive..should be later this week.
