Earlier this week I ordered 2 15" xxx's and 4 md3d amps. I have an Escalade and would like some opinions of what you guys would do. SQL is obvioulsy my goal with this sub. I was thinking subs up ports back? With Aero ports. Or should I do a wall behind the second row of seats? I am scared to f*** up the interior doing a wall, any suggestions on how to do a wall with out tearing up the interior?
