Review: Inexpensive and sounds awesome! - Replaces the front 2 dash speakers in a stock 2020 Subaru Forester, now my music sound so lively and much better than stock, even with the stock head unit this speaker shines. Will be replacing my door panel speakers soon with the same brand as well.
Review: Good sound for the size. - Cursed with 3.5.rear speakers in a 370Z, I decided to try these to make the best of it. Definitely sound better than the factory paper-coned Bose speakers. Great price for what you get for sure!
