Ok people either I am to tired or just blind. http://www.rockford-fosgate.com/rfte...412_812-TS.pdf
Is the specs for the 812 rockford i have. I want to build new boxes for each sub or together. Have not figured which. All I want to know is what is the correct air space needed for just one sub. All help would be great.
Ok I think I found it after looking hard enough correct me if I am wrong is it 4.697???
