I almost bought the MB from the same dealer. Got a chance to here the polk audio 10" Momo series compared to the mbq. Much better sound. Ordered a set of single voice coil from "woofersetc" (best price) they sent dual voice coils by mistake so I need to get a 1 ohm stable amp. to really get my power to them.
Haven't heard the kickers' so don't know about them.
