help planning a stereo in a convertible

[61ragtop]

I have a 61 drop top impala and am looking to fill out the sound. I have a pair of type R alpine 6 1/2 components up front in the vent holes (need to make enclosures for them as they are very tinny) they are run off an alpine amp as well not the deck. I also have a pioneer flip screen deck I am using too.

My main question is on the speaker box for the subs.........What should I use Sealed, ported, position, 10's, 12's?.........

I know i wont get record breaking sound with the convertible but would like it to sound clean and full.



Any recommendations would be great......
