When you’re looking to upgrade your vehicle’s sound system, replacing your factory sub can be tricky — many new subs just won’t fit in that location. Infinity’s engineers created an ingenious solution to this problem with the Reference Flex Series which allows you to adjust the sub’s mounting depth for a custom fit.
The FLEX8 8″ sub features a patent-pending adjustable flange which lets you customize its mounting depth. You simply loosen the flange, then slide it down the motor structure until the sub fits in the opening (keep in mind that this raises your mounting height). This unique, innovative feature gives you far more flexibility when adapting the sub to the opening in your particular vehicle. Along with the flange, the speaker’s low-profile design makes it easy to fit into your factory subwoofer opening for upgraded bass sound with minimum hassle.
And the sub’s rugged polypropylene cone and rubber surround give the REF-FLEX8 the stiffness to punch out deep bass notes while minimizing distortion. This sub will work well with most factory amplifiers, but will deliver even more impressive performance with an aftermarket amp.
To drive this single subwoofer, we recommend a mono amplifier rated between 110 and 275 watts RMS.
