I have a 10" DVC Bazooka tube.I had an old Alpine 3527 (25 x 4, 70 x 2 bridged). laying around that I hooked to the factory radio via speaker level inputs.At first I had an old Bose home audio sub hooked to it and it sounded OK, but didn't have the low bass I was looking for. I found the Bazooka for ~$130 shipped on
http://www.PriceGrabber.com and tried it.It certainly put out more bass, but still lacked the low bass I love. So, out of desperation I stuffed a couple of old t-shirts in the port of the tube and viola.... I had low bass. :DSince then I put the 10" sub in a box. It sounds the same but takes up a lot less room.Now, back in the day, I had an 8" Bazooka tube in my '92 Camaro and that thing had plenty of low bass. I don't know if the 10" is just too big for that tube design, or what, but the 8" IMO had better sounding bass.I'd use the 8" if I were to do it again.
