About the Hertz K 165
Start with Hertz
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.

These definitely sound way better than the tiny oem speakers. High notes and mid notes are allot higher and clearer. There's no crossover to install so installation was even easier.
