Went into Kartunes looking to add some better sound to my Toyota Tundra. After investing in a nice lift and other accessories it was time to give the stereo a face lift. The stereo lacked volume and bass. The tech was very knowledgeable on car audio and knew would work best on my tundra. After going back and forth we decided to go with a complete Audio makeover. I went with a Kenwood CarPlay radio which I could not be any happier with! Plug in my phone and control all my apps right from the radio! As far as the speaker setup I went with the JL audio brand which I researched my self before I came to Kartunes. JL audio may not be the cheapest nor most expensive but was worth every penny, definitely quality product. We picked a 5 channel amplifier to run all the speakers In the truck as well as the subwoofer. The sub woofer fit perfectly under my back seat. I'm thrilled with the results of how the system turned out as well as the service from everyone at Kartunes! I will be bringing my wife's vehicle next to Kartunes!
