The previous owner had already had the Blows system replaced by a nice Kenwood deck and speakers. I have thought that I might consider adding some more bass to the system. I am not looking for a rolling boom-box. The local audio/electronics salon guy showed me a subwoofer system that included an enclosure that took the place of the headlight aiming component tray. Pure stealth. No loss of cargo space. I think he was talking about an eight or ten inch unit. Anybody hear of this? It seemed a bit pricey @ $400.00 installed, but it's been a while since I shopped for this stuff.
