Port location,Opinions needed

[garychurch84 127]

My current box is 36"x16"x28" tuned @30 for 2 icon 12's.slot port.My question is would I benefit from building a new box with the port centered between the subs and fire the port thru the rear arm rest.Back seats don't don't drop down.98 pontiac gtp.

[cloud77 28]

is it sub back port back?

[garychurch84 127]

is it sub back port back?

which ever would work best,I was gonna have subs facing back seats an port firing thru armrest

[cloud77 28]

you could try that, and see how it sounds, but perhaps your subs facing the backseat and being closer to the front of the trunk will rattle the rear deck more

[garychurch84 127]

I just don't wanna spend $200+ on a box and it not benefit me any.As for the rear deck I'm already about rip that noisy sob out lol.

[cloud77 28]

I would say sub back port back would be the best sounding option in your case. Unless you want to look into a 4th order ported through rear deck.

[garychurch84 127]

So stay with what I have

lol,hmmm didn't think to try it in the rear deck

[lithium 358]

i run my subs IB (infinite baffle) so its mainly for plugging holes. 

[garychurch84 127]

I've also been thinking about this box being more for numbers if that changes anything

I know that stuff is sticky as hell

[Quentin Jarrell 671]

This is one if the instances is recommend a 4th order bandpass

[Julian 641]

I know in my first car they had to be firing into the rear or firing forward pushed all the way to the back for it to sound right/ be the loudest. Any other way sounded weird as if it wasn't loading correctly. A 4 bp may work like q said. Just depending on how much trunk space you're willing to give up I know theyre pretty small.

[garychurch84 127]

The demensions I posted in the in the first quote is the absolute biggest that can go in my car,anything bigger will have to be built in the trunk.

I'm wanting to to tune around cabin gain which is 40ish I don't know the exact sweet spot.while I was searching google I found one guy on SMD said. His 98 gtp peak at 44hz

I know the Icons aren't really spl but I feel there's more numbers to be had.this box will only be used when I decide to compete

If you are planning a comp "Burp" or 30 sec SPL enclosure I'd suggest tuning WAY higher than 44 htz ...

tbh I think I just wanna be a bit louder than my current setup I may only compete a few times a year.

I want to get a good bit of exp before I get that deep in

You could possibly tune to 57 htz and still get considerably good amout of low end bass ...

depending on enclosure build and euuipment being used ...

I'm just suggesting because I always see lower tuned "Cars" get their asses handed to them ...

They "sound" good and get loud ... but none of that matters to a SPL meter, which is the ONLY thing that counts in SPL competition ..

[95Honda 486]

Or just have 2 ports, one for SPL and one to sound good...

that's not a bad idea

[garychurch84 127]

This what I started out talking about.Would benefit any from firing my port thru here?

[Dictator 39]

not a bad idea but never seen a design like that before? any examples

[garychurch84 127]

I think it was a 4th order like mentioned earlier,I think there was pic give me a sec
