ILoveBass21 Posted August 18, 2012 Report Share Posted August 18, 2012 Okay so i have 2 sa 12s on the way and a brz1700amp, i am trying to design a box for my audi a4 that will be sealed off from the trunk into the cabin, i have never done this before and i am still learning about box rise, to combat box rise i would like to do an 8 inch areo port, as well as 45s and fiber resin. the space i have to work with is 35" wide, 17" tall, and 20 inches deep. i am aiming for about 4.2 cubic feet ( is that enough?) and around 35hz tuning. i just need a kick in the right direction!

IndianaBassHead Posted August 18, 2012 Report Share Posted August 18, 2012 Yes they can be. I was going to suggest tuning around 32 hz for daily if you listen to rap. Especially if you listen to slowed music. but 4.2 would be fine.

The 8" port would need to be about 21" for a 35Hz so it would need to be firing sideways. Quote Link to comment Share on other sites More sharing options...

IndianaBassHead Posted August 18, 2012 Report Share Posted August 18, 2012 If you aren't solely competing you really don't need to worry about box rise. there are a few factors though. Use the least amount of speaker wire and terminals as possible. Running speaker wire straight through the box to your amp would help a little bit. Also, smaller boxes tend to have less rise.

Also, smaller boxes tend to have less rise. i would still like the performance of a compition system, and its the little things that count right? and how about the bolts for speaker terminals? and using like 8 or ten guage wire for speaker wire?
