    • Sounds really good.
These changed the overall sound of my sisters honda civic. She couldn't be any happier. Fit perfectly into her car. You may need to buy adapter brackets to install them into your car without modifications but it can be installed with some minor modifications without the brackets.

So I started with the CS shallow mount 6x9 for the front door and they sounded not good at all. So I sent them back and I bought the Kenwood concert series 5 ways that are in the listing here and they are freaking amazing. They sound so good. A++ I haven’t given them an amplifier yet, but I am running a Alpine halo nine to them and Pioneer 2 3/4 in the dash with base blockers and haven’t done the 6 1/2 in the rear but I’m planning on doing the same Kenwood concert series and the rear doors. These Kenwood 6x9s rock. The fit was very nice. ... show more

Replacing the speakers in my Hyundai Accent 2009 was a breeze with this set of car speakers. They fit seamlessly into the existing slots, making installation a quick and hassle-free process. Once installed, these speakers delivered a noticeable improvement in sound quality, enhancing my driving experience significantly. Whether I’m listening to music or podcasts during my daily commute, these speakers provide clear and crisp audio with impressive depth and range. Overall, I’m highly satisfied with this replacement and would recommend these car speakers to anyone looking for an easy and effective upgrade. ... show more
