6.5" FKB116+4x6" FKB146 Car Speaker Bundle

This bundle pairs one set of MB Quart FKB116 6.5" speakers with one set of MB Quart FKB146 4x6" speakers, covering two different factory cutout sizes in the same car without placing two separate orders or hunting for a matching brand later. The FKB116 handles 240W peak power (120W RMS) per pair across 40 Hz to 22 kHz, and the FKB146 handles 180W peak power (90W RMS) per pair across 55 Hz to 20 kHz, so each size is built for the location it fits rather than one speaker stretched across two jobs it was not sized for. Both sets share the same build: an aluminum dome tweeter paired with a thermal-formed polypropylene cone, a butyl rubber surround that holds its shape through hot summers and cold winters, and a pure copper voice coil wound on a Kapton former that sheds heat fast enough for sustained volume. Heavy-gauge stamped steel frames on both sizes keep the cone centered under road vibration, and spade connectors or direct soldering work on either speaker at install. Buying the two sizes together keeps tone matched across the car instead of pairing one aftermarket size with a leftover factory speaker in the other spot.
