I searched to find the dimensions of the space under the seats, and found some people have run amps and even put in a sub under there.

Anyone know the size of the space there? I'd want to put either a Basslink or 10" under there, but I need trunk space...

 

It depends on your year, also, what kind of seats, and if you ever move them.
at one point, i was going to put the computer for my in-car-computer setup under there, but i determined (2005, regular seats, nav package) that i had almost zero space under there when you subtract all the space that gets run over when you move the seat around.

i eventually decided on velcro-ing it to underneath the glove box. plenty of extra room there.

 

i thought there was more space than that, like space either in the floor, or under the rear seats or something like that. I think people said there was just like foam in there and u pull it out.

I have an 06 w/o nav btw...

 

Read this thread.


Also: the dimensions I gave are for my '03. Have no idea what might have changed in later models.
