I finally bit the bullet and hooked it up.. It sounded fine but didnt get the volume i wanted (My sx 15 on 1000RMS (MD2D) got louder) and Im using a Sundown3000D (1600RMS@2) I have another 3000D on the way that im going to strap to feed it, i dont think its a power issue I think its the box... My question is, yoou guys running MT's how many cubes are you using and tuned to what?? Im going to build a new box out of Birch ply (1 piece design, using relief cuts for front, back, sides and port).. I think this box i have it in is a little small and not all that well built.... Im not asking for box plans, I can do that, i just have NO exp' with the MT... Help is appreciated....
