I'm thinking one for each side of the back where they do the stealth enclosures. They're cylinders I'd mount in stealth enclosures... anybody ever heard of a Tymphany 250 Linear Array Transducer? They're dual 8 ohm voice coil subwoofers. Anybody ever dealt with them before? I have 'em both in a 6l box that I keep under my hatch at the moment and do just as well as anything i've personally had up to this point. (single 12 or dual 10's)
