That helps a lot thank you and when I calculate the box freq I add the air factor (forgot name sorry) twice because of 2 subs right

[arcaudioman]

I didnt account the bandpass how do I do that?

[MrSkippyJ]

you have a sealed or bandpass box?

[arcaudioman]

Its a sealed box with mdf 3 inches in front of subs blocking off subs from rest of trunk with a 6" port between rear 6x9s

[MrSkippyJ]

you lost me there man. a sealed box with a port?

[arcaudioman]

Sealed box boxed in my trunk with a port from trunk to cab of car I think its called 4th order bandpass

[SnowDrifter]

So your subs are in a sealed box. But your trunk is ported into the cabin? Like a psuedo-4th?

Ahh ok. You shouldn't need to worry about a subsonic

BTW that's not a bandpass. Unless you reinforced your trunk to the point that it can be considered a box, then you just have a sealed box with a hole cut in your deck to let some bass through

[MrSkippyJ]

ahh, now it makes sense.
