05 Xterra Subwoofer

[mkaydude22]

I have a 2005 Xterra with the standard radio (1 CD, no satellite) and I saw on ebay a subwoofer specificaly fitted to the right compartment with the net (if you are standing behind the car and facing the license plate) in the cargo are. I think it was a 10" sub and that would be perfect because I do not want a sub sticking out and 10" is plenty bass for me. I tried looking for it again on ebay and on Google but had no luck. Anyone know what I am talking about or where I could get this?
