We picked these guys up for their Wake Board Tower Speaker line and all the cool products for the powersports industry....but they also had some impressive truck subwoofer/box offerings....so I picked one up for my demo truck and this setup is in Ryan's truck.
These are nice because they don't take up ALL of the underseat area, but they are perfectly designed to throw down some hammering bass. Also, since the amp is built into the box, it's a nice show piece as well and installation is a bit quicker than normal.
With the box being bedlined, it'll withstand anything you can throw at it.
They also offer 2 different styles of amps for these.....this particular one is an 800w RMS plate amp; but the other style is a 100x2 + 400x1...so you could power a set of front speakers as well.....so the flexibility there is handy.
If you've been thinking about adding some bass to your truck, come listen to this badboy...it might help make the decision for you!
