I am wanting to know if these numbers are sufficient for a vented enclosure for for a 12" BL. I will have it hooked up to a MTX TA81001 A 1 ohm in the trunk of my 06 Honda Civic. Any suggestions would be greatly appreciated.

• Width: 36"
  
• Height: 18"
  
• Depth: 15"
  
• Port Height: 16.5"
  
• Port Width: 2.5"
  
• Port Length 1: 11.75"
  
• Port Length 2: 6"
  
• Total Port Length: 22.25"
  
• Port Area: 41.25"
  
• Internal Port Volume: 917.8125"
  
• Port Volume Displacement: 930.5625"
  
• Box Volume: 3.909 cubic ft
  
• Tuned Frequency: 32 Hz
  

thats a huge box for a single 12", 3.9ft^3?!

shoot i must been look at air space for a larger sub i will redo it later this evening

Sorry about my mistake

you could even go a bit smaller than that if you wanted..but with those dimensions, after sub displacement you should have a nice, low hitting box

the volume is after displacement

i would go with a bigger port. but that could be just me. my port is 39 sq inches and im at 2.5 cu ft at 34 hz, and i still get a little port noise. so i would go bigger around 40 or so.

fast reply im actually thinking abot augmenting the overall desin to use a roun port couingout the top so i can I have the port fireing through my rear deck, there used to be factory 8" woofer there and it would be perfect.

i wouldnt do the port firing into the cabin with the sub firing toward to the trunk. i heard it is not a good idea. unless you go bandpass or face the sub towards the cabin and seal the trunk off.

but im not a pro. and you can try whatever you want.

hmm guess i need some input.
