I had to put my car down as a truck/other as well, even though it is obviously a japanese performance car :-)

Wish I knew more about subs - I got one for the Impreza due to some of Tony's comments a couple of years back, and it sounds much better, but I just have it piggybacking off one of the rear outputs from a cheapy 600 watt 4 channel amp using a Maplin passive crossover so I would imagine that isn't ideal.

The Forester seems to have a small (10" I think) sub built in, so we'll see how that sounds.
