How large is the speaker opening?
How deep a sub can you install in it?
Sealed or ported?
What is the internal volume?
Internal volume matches stock center consoe dimensions. It is approx. 11"high, 6"wide, and 8" deep internally.
It has a 6x9 installed with some version of a frequency limiter to low wave lengths.
It is sealed.
Here is a pic of the internals:
