Kicker time 

I just took out the stock behind the seat paper sub. And put in a kicker substage 12 inch woofer and amp. For what it is ,plug and play.......its knocks like 2 12s in the truck of a car. I've had a system in every thing I have owned and for the cost and the convenience of the kicker that is molded and made for my truck you can't beat it install time was about 45 min. And the sound is great. All In I spent 5-600 bucks on e bay.

Total Cost: $600
