    Review of JBL GTO629 6.5″ Coaxial Car Audio Speakers

    Pros:

    • High sensitivity for increased sound level
    • Adds low and mid frequencies nicely
    • Excellent tweeters with clear sound
    • Adaptor plates included for easy installation

    Cons:

    • Confusing wire polarity picture in installation instructions
    • May require additional bolts/screws for installation
    • Shipping speed/delivery times may be slow

    I found the JBL GTO629 speakers to be a great addition to my car audio system. The high sensitivity of the speakers resulted in an increased sound level even with the same volume settings. The speakers complemented the existing components in my car, adding low and mid frequencies nicely. The tweeters provided exceptionally clear sound without being too sharp. The included adaptor plates made installation clean and professional, although I did need to source additional bolts and screws. Overall, a very nice set of speakers for the price.
