goldtaz: advice and recommendations are always welcome //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif . ok well lets say aeros were an option...how many do i need as compared to a standard slot port? i know you dont need as many, but i have absolutely ZERO experience with them, so im not sure how they react.

I would do at least (4) 6" aeros with the amount of cone you have. If you do the slot port again, I would recommend something like this.

we did my friends box (as well as 1 of my old 2 15" sx box) the same way except the port was all the way across the bottom of the box. why exactly is it better than the port i have now?

goldtaz: forgot to ask...why is the port in the middle a bad idea?

In my experience the box I mentioned above is simply louder. As to a theoretical reason it is louder, I do not claim to know the answer (maybe someone a little smarter will chime in). If I just simply were to guess, it would have something to do with directional air flow and the fact that your box is basically 2 chambered having some form or fashion of cancellation. Just my $.02.

ahh ok. i appreciate you taking the time to answer

edit: ****! i didnt notice that going from 2 18's to 2 15's would loose me almost a whole 15 worth of cone area //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

yea george but cone area means shit if u cant have the proper box lol. i went with more cone area but also i have the proper box space. hell actually im @ 18.37 cubes After Displacement. so around 4.5 cubes per 15. im about to start my build camp so i will have plenty of pics so feel free to chime in an steal some ideas.

most definatly. reason for my last post was because i was rethinking for the 1000th time of whether i want to give up my back seat. and i started thinking:

1) give up the back seat for that theoretical "1.5db" increase with the 18's

or

2) just sell the 18's get the 15's and keep the back seat even though your loosing out on cone area.

i can make a proper box for the 15's with the seats up and 18's with the seats down. only reason IMO that this one came out like shit was due to me trying so hard to keep the back seats up.

let me know when your going to build, i would love to see some pictures!

so youre talking about changing from the 18" BL's to 15" BLs?

 

[sku 10+ year member]

Why all this churn...it's pretty simple...

Build the box you want and think will work best for the 18s. If you still don't like it or it's still not loud enough you can:

1) Just take it out. A box is not a permanent thing.

2) or you can try adding more power to it.

3) if you are still not satisfied go with the 15s approach

So to recap...you've tried both options here...and have really only spent the time and money to build another box...

My personal choice would be to try option 0. Face the subs back...I know you said you don't like the sound but actually my impression of subs back is totally opposite of yours...you can actually feel it more and hear it more...

With this option you've spent 0 dollars...and can still go back to your current setup.l

Just play with spacing from the rear hatch...

^^^ I enjoy that setup as well for a daily driver

I say go to a 10" Q in a T-Line with about 1000RMS.

Good thing I was being sarcastic then, since I don't think George would like it either. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

If you can get 16-20 cubes with the backseat out, why not go with 3 18s?
