Description
Metra 72-4572 — Later-GM Full-Range Speaker Harness Pair
Use 72-4572 when the supported GM full-range speaker location uses this factory connector, including many Silverado/Sierra door-speaker applications. It keeps the factory vehicle harness intact and gives the aftermarket speaker a serviceable plug-in connection.
Sold as a pair. This is not the amplified dash/tweeter connector—72-4573 is the separate later-GM small-speaker architecture. The harness solves the electrical plug only; mounting adapter, depth, factory amplification, impedance and acoustic fit still need to be checked.
Where this fits in the build
Speaker choice should follow the listening goal and the location it has to work in. Factory replacement, sound quality, loud daily and high-output builds have different priorities.
