Alpine DM-65-G 6.5" coaxial speaker set

The Alpine DM-65-G is a pair of 6.5-inch coaxial two-way speakers designed for car audio upgrades. Rated at 50W RMS and 200W peak power with 92dB sensitivity, they suit drivers replacing worn factory units who want louder, clearer sound without adding an external amplifier. The 4-ohm impedance matches most head-unit outputs directly.

Metra 72-4568 GM wiring harness

A Metra 72-4568 harness is included for select 1988-up GM vehicles, letting you plug the new speakers into the factory connector without cutting or splicing wires. Rubber surrounds and injection-moulded bass diaphragms resist vibration and moisture, while a Tedoron tweeter diaphragm and neodymium magnets handle high frequencies. Protective grilles are supplied for a finished look.

Factory speaker replacement and upgrade value

This bundle replaces original equipment speakers that have lost output or developed distortion, delivering a 65Hz to 20kHz frequency response that restores missing bass and vocal detail. The jump is worth it when the existing cones are torn, the foam has rotted, or the head unit cannot drive the old coils cleanly. Buyers needing deeper sub-bass below 65Hz or component-level imaging should consider separate subwoofers or component sets.
