I have built thousands of these. The seat always latches.
Make sure you pull the box forward towards the brackets in front until it closes.
Also, I am assuming you removed the brace from the passenger side?
It's a tight fit but if you get it positioned correctly it'll go down.

Box is okay, but the passenger seat does not latch as promised. I rewatched the product video on youtube and you can tell the passenger seat in the video doesn't latch either because he doesn't pull the handle to lift it.

I needed a box for a single 12" sub for my 02 2500HD crew cab. This is the only box i could find that had the mounting depth and air space I required. The box is built well and fits perfectly. customer service was very fast and helpful, If i ever need another box I'll purchase fro soundoff in a heartbeat. Very satisfied.

I just put the box in my truck and it fits the odd space well. I am a little concerned about how close the surround is to the one bar on the passenger side, but Matt says it will work. I'm willing to take his word for it for now.
I am using 2 Kicker CVR10s I don't have the amp installed currently. I will comment back when the whole system is up and running. I wonder if a ported box of this size with one 10" would not be better. We'll see.

This is the best box on the market hands down,i looked for a long time looking for a box that would fit my truck and sub. i was more then happy with the quality of this box and how well it was made.
I put 2 sundown audio sd-10's and not only do they fit perfect but the sound is great i will defiantly be buying my next sub box from Sound off

I just got my box from sound off audio and I must say its a great product. I normally take the time to build my own boxes but this one seemed a little more than I wanted to tackle and I didn't have the time. So coming from a guy who knows good craftsmanship when he sees it this product is top notch
