Re: Looking for compact subs. (boybaha)
Basicly I did the thing you wanted to do, keep the system stock but add a sub that would not take up much space. I put in a Boston Acoustics C110. Its a very small 10" sub in a pre-built box. It uses about half a cubic foot of air space and the box is less than 1'X1'X1'. Check it out here, http://www.bostonacoustics.com/ProductsPage.asp?ProductID=128&SpecID=6&SeriesID=37 Honestly you probably can not go much smaller than that or as you said one of those q-logic or thunderforms. Maybe you could put a 8" sub in the CD changer location but I dont think that would be deep enough but I might be wrong. Check out that boston I showed you, it is pretty small, fits in my 2002 jetta great, and has very good sq. Gooc luck.
