Kappa's are always good. They really sing with 100 watts. Clean and loud. 5 stars for infinity and 5 stars for the seller's sale price being better than crutchfield and my local shop. Read more

I used these to upgrade the speakers in my jeep. Overall they are much better than the factory “premium” speakers.
