My clubs stay at my course, but if need be they do fit in the back seat. The other three guys need to make their own way to the course for our tee time. Hockey bags/sticks, there's a challenge!
The woofers could shake the trunk, but I have the system dialed in so it's musical rather than boomy. The kids in the Honda Civics value loud, I lean towards musical myself. When I need to put stuff in the car it either goes in the back seat or the passengers seat, or I take my other car. This is my summer car, it's impractical to drive a rear-wheel drive beast in the snow (my 2001 Acura 3.2 Type S does a fine job in the winter; front wheel drive and four snow tires on it). The spare wheel and tools are in the compartment under the amps where they belong, no worries. The entire trunk is esentially a carpeted free floating board that can be removed if you find yourself on the side of the road with a flat tire. As for the transmission, well the car was available and mint so I tolerated the automatic tranny. I did blow the head gasket a few years back and took the opportunity to redo certain elements of the engine, it's 320 hp now.
