Bought the subwoofer package for my 2021 Toyota Tundra Crewmax with non-JBL sound system. The price of the subwoofer package is excellent (nearly 1/3 of the other offerings). The quality of the bass is very good. I had questions about the installation and the customer support was excellent and would get back to me very quickly. I damaged the amp volume knob during installation and they shipped a new one free of charge. The only issue I had (hence the 4 star, not 5) was the subwoofer box: it would fit behind the rear seat, but you could not fold up one of the backseats (60/40 split). I moved it around and it was an either/or situation. You could only fold up one of the seats. I settled with 60 split seat folding up and 40 split seat not folding up. Honestly, I never fold the seats up (I just use the truck bed) and can live with 40 split seat not folding up (though it is doable with some effort). I would recommand Skar.
