CJ18 Posted December 3, 2012 Report Share Posted December 3, 2012 port up is a good compromise. It still wont load quite like if you could fire the port back. I have done both and with the port back, it played so much lower. Can you at least post pictures for us? Quote Link to comment Share on other sites More sharing options...

Piggi3 Posted December 3, 2012 Author Report Share Posted December 3, 2012 An what should I tune at and how many square inches of port Quote Link to comment Share on other sites More sharing options...
CleanSierra Posted December 3, 2012 Report Share Posted December 3, 2012 No one said to fire the subs back, only the port back. Subs go up, port goes back. Airspace for cone control NEED to be considered if contemplating using that second amp. Quote Im not the one you want to try to troll. Just a fyi for you.

CJ18 Posted December 3, 2012 Report Share Posted December 3, 2012 If you are going to use both m4as, you need to be around 2.75-3ft3 net per sub. I know that sounds small, but out sub do very well in smaller boxes. I like 14in2 of port per ft3 and I would tune around 35hz. That should give you the ability to play down to 28-30hz Quote Link to comment Share on other sites More sharing options...
Piggi3 Posted December 3, 2012 Author Report Share Posted December 3, 2012 I never said subs back I said port I can't because the box goes up against my batteries an thanks Cj for all the help gonna make the same box but just cage the port up as well as te subs an see what happens with 1 amp then add the other and see te difference Quote Link to comment Share on other sites More sharing options...
CleanSierra Posted December 3, 2012 Report Share Posted December 3, 2012 I'm not ignoring I am gonna buil a new box same dimensions but fire subs up port up with port at the bak going across the whole box at 3" wide by 38". I have 2 mechman 270 alt and 4 nsb90s with 4 1/0runs from alternator back it should be enough. I can't fire subs back like people are saying because telhe batteries will be right against the port an will interfere So that's my idea for now You said RIGHT up there "I can't fire subs back like people are saying because..."
