Exact Dimensions under the front seats...
 

Question:
What are the exact dimensions of unused space underneath the driver's and passenger's side front seats? H x W x D between mounts and between valences?

Yes. I searched.

No. I did not find an answer that meets my needs.

Good News: If no one responds, I will find out for myself and post on here.

Background:
Since the 4Runner is officially no longer under warranty (60,000 miles in 18 months), it is time to start the modifications! From my 2008 Tacoma I have an older model Pioneer Premier Series 10" Slim-line Subwoofer, a mono-channel 500W Pioneer Premier Amplifier, and a ton of other audio stuff that I am still in debate whether or not to install. We use almost every inch of our 4Runner. That being said, my old subwoofer needs a home, and I want a project I can afford to do. Having better sound out of the stock HU wouldn't hurt either. We travel quite a bit through all kinds of terrain and weather. As such I can't "undo" the heater vents under the seat either. The air must flow.

Objective:
I am looking to utilize as much of what I already have laying around the garage in my 4Runner since we are still re-budgeting from moving into the new house. This is why I am not going the more popular route of doing the same setup as @Antman :fishing: and so many other people. I am fairly convinced I will need to build a custom enclosure for under the seat (if I can even fit an appropriate sized one under there). However, in a fit of laziness I am hoping I can squeeze this under there.

Obviously my custom built box from old Tacoma isn't going to fit under the seat...

Any information given before I take the seats out myself would be greatly appreciated! :cheers:

Reserving this post for "the answer" to the "the question"...


...and, no, it is not 42. ...this time.

Did you ever find out the dimensions or get the sub to fit?

I have the same sub and would like to do the same.

This is a 6 year old thread. The guy is probably long gone from here.

If you're worried about space, you may want to look into seat jackers;
