Well I'd definitely go optimal sized as long as it fits in the trunk of my galant, one thing I was curious about is how should I tune it. What effect do different tunes have on the sound?
I got an icon 12 recently, it's in a sealed box, and I Love how low it goes. If I really turn my radio up it gets Loud and sounds clean. Thing is I think I'd like some more output, but still want it to get nice and low and sound good. I listen to mostly industrial, a bit of triphop, and rarely metal and rock, what would you recommend as far as a ported box goes?
