JL is the way to go.
Crutchfield Customer Review (What's this?)
Almost too much for my 2013 Tundra Double Cab. I paired it with the JL Audio JX500/1D and WOW! The gain on the amp is set to around 2/3 and it sounds amazing. JL is the way to go. The sub barley fits under the rear seat. The support for the seat cushion slightly bent the outer edge of the grille, but it fits, it's out of sight and I'm pretty confident it will not interrupt the sub. Low end response is mean and none other.
Pros: Made by JL.
Cons: Made me realize how much my truck can rattle.
