Box for BTL

[shortyg83 10+ year member]

Ok so I have an Fi BTL. And my car is a hyundai tiburon. The sub is 15 inches.

Right now it is in a box i built for my old 15 inch type R.

The box is not made of MDF it is made of particle board. The box is 2.83 cubes and it is tuned to about 34hz. I am Building a new box tonight which will be made out of mdf, dimensions will be height=16.5 width=36 depth=15.5 with a 3 inch port and tned to 34hz. it will give me 3.56cubes. Do you think I will notice an actual differnce in sound from this?

3 inch round port or 3 inch wide slot port?

3 inch slot port.

i would still give it a little more area if you can fit.

How much power you planning on?

 

[shortyg83 10+ year member]

The amp I have is the hifonics herc. It's putting prolly around 2200 to 2300 rms

alright.

I would see if you could fit a 3.75" wide slot port.

You should definately see a gain, as the btl will need much more port area and a much stronger box than the type-r.

I would consider doing a double baffle.

Yea I will def be doing a double baffle, I will check the port I just need it to not take much more space up in the box.
