PowerBass S-275CF 2.75" car speaker

Direct OEM replacement speaker

The PowerBass S-275CF is a 2.75-inch full-range coaxial speaker designed as a direct replacement for factory units in many Chrysler and Ford vehicles. It targets drivers who want improved audio clarity without modifying door panels or dash openings. The compact format suits tight OEM mounting locations where larger aftermarket speakers will not fit.

Fixed 2.75-inch mounting constraint

This speaker uses a non-standard 2.75-inch frame that matches specific factory cut-outs rather than common aftermarket sizes such as 3.5-inch or 4-inch. Because the basket diameter is fixed, it cannot be adapted to larger openings without custom fabrication. Buyers must verify that their vehicle’s original speaker matches this exact dimension before ordering.

Confirm factory speaker size and wiring

Check the existing speaker’s physical diameter and mounting depth against the 2.75-inch specification to ensure compatibility. Verify the factory connector type or prepare for basic splicing if the harness differs. Ensure the head unit or amplifier can drive a full-range driver of this class without requiring a separate crossover network.
