gorrect, subs firing up towards the roof, and port firing backwards towards the rear hatch

 

Keep in mind that the sound will be 90 degrees out of phase.

 

hmmm i want more SPL when i get my subs but i dont want to make a custom box lol

 

granted there are some differences based upon what there fireing against, the enclosure, and the **** in the car. but as the frequency gets lower the sound should become less directional.

 

Definately cant have one without the other. Building a custom box is the best and cheapest way to bring the full potential out of your system...

 

all frequencies below 300hz are omnidirectional. That has nothing to do with the phase though.

 

Sub and Port being 90 degrees out of phase really isnt going to make an audible diffirence unless you get lots of cancellation.

 

yeah very true.

 

all depends on the vehicle and the location of the enclosure. Ive been in vehicles with a situation similar to this where it absolutely sounded horrible because of the phase. AFter severley messing with the T/A we were able to get the back into phase. Im not sure how it will perfrom in a blazer though. Wouldnt hurt to try. I was just saying its something to keep in mind.

 

so who wants to build me a box?
