Introducing the deepest box commercially available for your 99-06 and 07 classic GM extended cab pickups. The Ultra Deep Maxx box is not only deeper than our Ultra Deep box, but has more volume and more clearance for your high powered subs. Think of this box as our famous Ultra Deep box on steroids. Now you can easily fit subs like JL 12w6 and Alpine type Rs in a box under the seat. And since it's a downfire box, it stays completely under the seat and doesn't stick out and interfere with your rear passenger's leg room and the subs are hidden from view. The best part is that it does not require a seat lift. The seat will still close normally down to the stops and lock into place as usual. This box uses 100% 3/4" MDF and is glued, countersunk and screwed, and caulked. It is deep enough to fit many of todays deeper, beefier woofers, including: 12" Alpine Type R, 12" JL Audio W6, 12" Kicker CVX, And Many More. If you are serious about getting some major slam into your truck, then pick one of these bad boys up today.
"Just installed my two CVR 12s in this Ultra Deep Maxx box. Wow this is definitely a quality box.. I'll never get another cheapo box again..there's a reason those other boxes only cost 100$ thanks for the best sounding bass I've ever had"
