Alpine SPJ-161CS 6-Inch 2-Way Component Car Speaker
Elevate your in-car listening experience with the Alpine SPJ-161CS — a 6-inch (16 cm) 2-way component speaker engineered for drivers who want rich, detailed sound without factory speaker limitations. With premium materials, a wide frequency range, and a compact mounting profile, the SPJ-161CS is a straightforward upgrade that makes an immediate difference.
Why Choose the Alpine SPJ-161CS?

Whether you're running it off a factory head unit or an aftermarket amplifier, this speaker performs with consistency and clarity.
