About the Hertz K 165

Start with Hertz
I can be a heel-dragger if we're talking DIY projects, but when it comes to upgrading to new speakers, I always regret waiting. Going from the fuzzy crackly-ness of old factory speakers to clear and present sound is always rewarding. Hertz's Uno Series car speakers give you a way to do so with solid power handling and trickle-down design elements from competition-level audio engineering.
Factory replacements
With aftermarket power up to 75 watts RMS, this Hertz's Uno Series K 165 6-1/2" component speaker system employs a treated paper cone and foam surround for low-frequency excellence and a separate PEI dome tweeter with an integrated crossover for crisp highs. Hertz includes tweeter installation solutions for a variety of mounting styles.
The Hertz philosophy
Hertz believes that a good speaker should reveal the emotional power of the music you love. That's a high bar, but with their commitment to using premium components and boundary-pushing design, they're more than up to challenge. Comprised of music lovers, Hertz is committed to optimizing your car's system for total audio enjoyment.
Grilles are not included; the factory grilles should be suitable for most applications.
