True that we tested Re Mt's the older ones we tested the Db WDX's and crossfire subs all with the same score on the same power which was only 24k re 4 spider db 3 spider xfire 3 spider. You have to do your own testing and find out whats gna work for you. You may hate dc or db or rd or whichever. I would definately test with what you have so you have good notes for reference especially if your changing up the box, makes sense thats just my opinion
