Powerbass OE275-GM OEM Replacement Speakers Chevy / GMC

The Powerbass OE275-GM OEM replacement speakers provide an immediate acoustic upgrade for factory sound systems in GM, Chevrolet, and Cadillac vehicles.

Built with treated paper cones and a 2.5 oz (70.9 g) magnet assembly, the speakers offer reliable durability and refined sound fidelity across a frequency range of 150 Hz to 19 kHz. With an impedance rating of 4 ohms, they deliver balanced output while handling up to 25 watts RMS and 50 watts peak power.

Designed for straightforward vehicle integration, these speakers feature custom nylon OEM speaker adapters and factory-matching plug-and-play wiring harnesses. This direct-fit setup utilizes existing factory mounting holes and connectors, eliminating the need to modify vehicle panels or cut factory wiring during installation.
