Great sound!

Nice fit. Sound great with factory stereo. Can't wait to hear what they sound like with my new Alpine deck.

Huge improvement!!

These replaced the factory speakers in my Honda Accord. Since they are 3 ohm with a 92db sensitivity, I didn’t loose volume like you usually do when installing aftermarket speakers on the factory head unit. The clarity is a huge night and day difference. The tweeter ok these have a a built-in crossover on them, which makes the highs so crispy. It’s only a 6.5” so it doesn’t produce a ton of bass, but the overall spl is outstanding. If you have a sub, these things will compliment the bass so good. Give him a try, you’ll love them
