more space?

I posted this somewhere else...just thought i would ask here.

Alright...i have a 99 accord EX V6. here is my problem.
I have an alpine cda1003 and an alpine eq below it. now that takes up all the space where the stock headunit was. I have a playstation 2 under my passenger seat. I want to get rid of the playstation cause it is just about the most annoying thing to watch movies on. so i bought an alpine dva5205 dvd player. I am not sure where to put it.
do they make something to put a audio unit underneath, where the big space is near the cigg lighter? please help me out...this is annoying.
