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. If you are serious about getting some major slam into your truck, then pick one of these bad boys up today.

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

Wow! This box is amazing... I have two KICKER CXV 2 ohm subs in this box. Not CVR, CVX! hooked up to a Hifonics Colosuss... Needless to say, it sounds awesome, hits so freaking hard... It's deafening at times... Well worth the extra cash, if you want some serious bass in your truck!.. Rating: [5 of 5 Stars]

the box looks nothing like the pictures on here.. i weigh 180ibls. i have to sit down and kinda push down to get my seat to lock. i e-mail sales twice . they never respond back. i think i lost air space. my subs do sound good. but they do bottom out... i think if they left the design like the pictures on here. i would have more air space and will be able to push more to my subs. i'm using memphis m3 12' subs dual 4ohm voice coils. they do pound and sound good. but the customer service sucks. and won't respond. thats why i left a neutral. feedback. there is a nice gap in between my box and seat...
