To adjust loudness, you just have to lower the gains on the amp to provide a cleaner signal for the sub.

With my 10" RF sub before, I used a 12x12x12 (inches) sealed enclosure that came out to around 0.75 cubic feet which was good enough for in-car listening.
I really don't know the specs of the box but I assume siguro naman. Anyway is it a good idea to take it out and refabricate a new box? And is it okay to have a circle shaped box so long as you met the proper volume?

Another question: what's the best tweeter location? The stock location of my Tweeters are on the dash , facing the windshield. I'm thinking of getting some tweeter pods and relocating them
