ok for my bro's birthday im going to build him a new sub box...as of right now he got sum audiobahn sub box...

here are my concerns/questions

when you say its tuned to like 34 hz ... on the head unit if i put the subs to 34 hz will the ubs sound the best?

with the current box its a bandpass one..with the new box its going to be ported, will the bass be more feel-able??

and last one, with the new ports, can i like extend the ports so they come out of the rear deck so the air its pushing will be into the cabin??

thanks
