About the Hertz K 170

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.

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

Handling up to 70 watts RMS, this Hertz's Uno Series K 170 6-3/4" 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.

Customer Q&A

2 questions already asked

Q
K 170 lacks bass/low end. Help?
[ Andy  Apr 15, 2021 ]
1 answer
A
The K 170 in my experience are great mid speakers, they sound amazing for the price, as far as bass is concerned, they are slightly better than my stock but not by much. If you want any kind of bass I would recommend a subwoofer. Even a small 8in will get the job done depending on your vehicle. These due pair great with my setup, I am able to play as loud as my ears can handle with no distortion.

Q
Which grills cover these speakers?
[ David  Apr 03, 2020 ]
2 answers
A
Factor Grills
[ Erik  Apr 04, 2020 ]
A
Typically on most cars the factory door panels cover the speakers (which is why most speakers don't come with grills). Crutchfield does a great job ensuring that the speakers fit the top and bottom mounting depth's when you input your car's info.
