The Pioneer TS-M651PRO is a 6.5 inch car speaker intended as an upgrade for standard factory installations. It is rated for up to 500W peak power and provides higher power handling than many stock speakers.

The speaker installs into standard 6.5 inch openings and can be used with factory head units or aftermarket amplifiers. For best results match speaker impedance and use appropriate amplification or crossover as required by your system.
