I think getting either of those subs would be a step back from the DDs as far as SPL is concerned. What amps are you using?

Wow that's a great effort taking into account you're using the OA amps!

Got any pics of your enclosure you wanna share? :)

More power :D :D

I dunno if changing from 95's to MT/BTLs will do much for you... that said, I know of someone selling a 9912 if you could find a partner for it ;)

If you're already hitting 152's there's not much I can tell you - thats a hell of a lot higher then Street DbDrag is hitting here (New Zealand :D)

Maybe go bigger box with more port area to increase efficiency? Otherwise just get more amps :D
