First step was to see if a 10" sub would fit. I thought it would after taking some measurements.

Next step was to evaluate the existing storage compartment.

I sealed it best I could using Peel & Seal tape from Home Depot. It's not perfect by any means, but it's a first attempt. This acts as a sound deadening material like Dynamat.

I put the carpet back in and removed the plastic frame.

I made the baffle out of 5/8" MDF. The rubber hose will act like a grille, allowing the sub to mover without it hitting the bottom of the seat. The MDF was primed, painted, and ultimately covered with spray on truck bedliner (as well as the hose).

Coated with spray on truck bedliner

You can see the difference in height between the hose and the sub.

Here it is in place, but not screwed down. I added the peel & seal to the underside of the baffle and added a rubber weatherseal around the perimeter to help with a seal and vibration.

I will add polyfill to the storage compartment before I screw it in place.

I'm having my Amp, wiring kit, and new head unit install next week, so I'll update the thread regarding performance. It may not sound good. I'm not sure. I've found several of these installs on the internet and they say it sounds nice. We'll see. Thanks for reading.

I have a similar setup in mine, but I made a sealed enclosure for underneath. There is a set volume of air that needs to be trapped behind a 10" sub, and the way the rear seats are in those tundra's, the air pocket is too large. There is an air gap under the carpet between the left and right seats that is just big enough to get your arm in (almost exactly under the orange pipe wrench handle in your 1st picture). I would suggest filling this passage with some sort of foam or other insulating material to prevent air from moving from under the sub to the left side of the truck where the factory jack is stored. That should greatly improve the response and sound of your sub.

Otherwise, looks great!

...or the air gap may make the sub sound better because it can use the volume of the other compartment as well. I'm assuming the Dynamat sealed that hole though.

looks great let us know how this sounds want to do something similar in my ac.

That's where the ladies sit :beavbutt:

I got it all hooked up last week. I added some polyfill to the enclosure before screwing it in place. I have a 460 watt amp installed under the passenger seat. It sounds very good. It sounds even better with the seat up, but I cant really have it up with kids and cargo sometimes riding along. I also installed a Pioneer BT6500 head unit. That gives me better control with everything (highs, mids, lows, designated sub control). In the future, I'd like a new amp with remote to control the bass from the drivers seat. I'll try and get something up on youtube.
Thanks for commenting.

Here's a short video on the sub. This was shot right after installation of the sub and the Pioneer head unit. The settings had not been adjusted yet for best sound quality on the stereo and amp. Also, this was shot on an iPhone and you're probably watching this on a computer or mobile device, so keep in mind that it is not an accurate representation.

It sounds even better with the seat up

Perhaps putting a more rigid spacer between the sub and seat would allow the cone to move more freely and give you more SPL. Try temporarily placing a couple wood blocks on either side and see if that makes any difference.

Yeah, I was thinking about adding a bar or something. Maybe a long straight drawer pull or two to span accross. The rubber hose works for the most part, but not 100% of the time.

Maybe a long straight drawer pull or two to span accross.

What if you mounted the sub to the underside of the cover piece? That would give you an extra 1/2" or so of clearance on the top side, then you probably wouldn't even need the tubing.

great idea. i have to make sure i have space. I'll do some measuring. Thanks!
