im thinking of a new trunk set up that i have to start working on,i got some ideas when i came across this pic, these subs are not in a box, they are just screwed into 3/4 inch mdf then the mdf is screwed into the rear deck..i read the artical and its called "free-air" set up, now i got a question, would this sound good??, right now i got 2 12" memphis in a ported box and there loud so if i set them up like this i dont want to loose the sound of them, will i? comments? thanks

Fee-air subs are a special sub with a ridiculously stiff suspension. If you just put yours back there it would sound like poo even though the trunk seves as a makeshift acoustic suspension. Do this for your subs but build a box under them. That's what I am gonna do.

 

I disagree. Free air subs work fairly well if installed right. In order to pull a free air sub gig off, you got to completly keep the top and bottom of the subwoofer to successfully seperate frequencies.

Now mill$civic. Do you have any idea what consits in a honda civic up under the rear deck? You will be into some serious custom modifiaction.

 

your right memingtion870_20ga,i was just thinking about whats under my rear deck and it would be kinda tuff to do this, but u say that i have to keep the bottom and top of the subwoofer to successfully seperate frequencie..could you please explane a little better?

 

Questions?

ahhhhhh i get it now, hum i have an extra sub laying around i could try doing a this project, thanks remington870_20ga

 

no prob [sm=smiley20.gif]

 

Yes its actually called infinit baffle. The top and bottom of the su must absolutly posotivly not be abple to leak to the other chamber.


BTW some subs this wont work on.

 

and if u do it wrong its goin to sound like an 350lb woman farting.

 

yup. A good example even though I hate to admit it, is an acura tsx? type s, with the bose system[:'(]


Another good example, is the Harmon Kardon system in the 3 series bimmers with subwoofer package.
