Enclosure under the front seats...

[94S2Sedan]

Im Building a nice system in my Saloon, But i dont want to put the Sub in the trunk...
I had a 10" Rockford P3S in my last car and the rear seats muffled the bass to much, there was no clarity either. Needless to say that the rear section of the car started to rattle pretty much right away

First Question: Has anyone ever built a sub enclosure under the front seats?

Second Question: If so what size? and what Brand/Model...

I think you can buy a pioneer underseat enclosure with a 10" sub off the shelf
