6.5" Front+Rear Speaker Replacement For 1996-2001 INFINITI I30

This kit replaces the front and rear speakers in a 1996-2001 INFINITI I30 with two matched pairs of MB Quart FKB116 6.5 inch 2-way speakers, so the factory front stage and rear fill sound like one system instead of an aging factory pair up front paired with a mismatched aftermarket set in back. Each of the four speakers pairs an aluminum dome tweeter with a thermal-formed polypropylene cone, handling 240W peak power (120W RMS) per pair across a frequency response of 40 Hz to 22 kHz. A butyl rubber surround holds its shape through hot summers and cold winters, and the pure copper voice coil, wound on a Kapton former, sheds heat fast enough for sustained volume without breaking down. A heavy-gauge stamped steel frame keeps the basket rigid over rough roads, and spade connectors or direct soldering both work at install. With a 5.59 inch mounting cutout and a 2.13 inch chassis depth, this pair drops into the factory front and rear locations on the INFINITI I30 without new cuts or extra brackets. Because the front and rear speakers come from the same model, tone and output stay matched end to end, which is the part a mismatched aftermarket swap usually gets wrong.
