So I will be ordering an OA-12v2 D4 very soon after selling my current system (Upgrading from a Fosgate Punch P2 12, 2011 model). I have a Rockford Prime P500-1d to work with, so the sub will see just over 500 watts. I have read in many places that the more power, the smaller that the box can be, and the less power, the larger you can build the box... generally. So I was thinking of doing a 2.5 cuft enclosure for the OA, on the 500w. It will be going in the trunk of my 2000 Civic sedan, most likely sub back, port side. Does this sound appropriate? Is there another way I should approach this? The box will be tuned to 30Hz via 4" aeroport. Thank you for any help, and I apologize if I left out any important details.

That would work rather well, but in all honesty I would utilize a slot port in your application if you have the space. You can adjust port area and volume a bit to help make the enclosure more efficient. This would help with getting more with less in a since.

If you are limited on space and/or plan to upgrade power, I would slim the enclosure down a tad.

What amount of port area would you recommend in this application? It is a daily driver setup, and I'd like as much bandwidth as possible.

      Round number two for the real deal. Started planning and collecting for this build a few months after I got the car, so basically a full year now. Don't really have an idea for goals yet, I hope its loud and I will get it metered in the spring. Super close to tearing into it and getting it done, waiting on a few more things to arrive in the mail.
      2001 Honda Civic Sedan ES1
      Singer 320A
      Soundrive SDA3 12's
      Taramp's HD8000 Ex
      PPI 900.4
      Xs Power D5100 & 3100 (maybe more battery coming)
      4/0 welding cable
      SHCA Fuse Holders / Speaker Wire / Battery Terminals
      Kenwood X399 HU
      *Possibly going with SSA Evil 6.5 for mids, no clue on tweeters yet*
      Lots of misc stuff to make it all happen.... on to the pictures.
      The car

       
      Box design, 2.3 ft 30hz 

       
      In the trunk. I will be make a front panel for it and completely sealing off once I finish wiring in batteries etc.

       



       


      Still waiting on my 16 ton crimper, triple 4/0 inputs, probably get some quad 8 awg for the speaker terminals whenever they are back in stock. Still need a shorter belt for the alt and just small stuff to wrap it up. Advice etc always appreciated. Thanks for stoppin in for a gander!

      Hey everyone, 
      First off I wanna apologize for changing my mind so much. My financial situation has changed, so my future setup ideas have too. Even though I have not followed through with other plans ya'll have helped me with, I have learned a lot for each comment or post I read.
       
      On to the enclosure idea. I will be getting a single SA-10 D2 as soon as my current setup sells. I will be running it off of a BRZ1200 @ 1 Ohm (for headroom). My goals are for it to be decently loud (I have had an E-12, hope to be comparable to that), and flat sounding for all music types... From dubstep to decaf to classic rock to country. It will be in my daily which is the trunk of a 2000 Honda Civic Sedan (DX EJ6, D16Y7 Auto). I am planning on building an enclosure that is 1.4 cubic feet, with a 17" long, 4" aeroport, tuned to 34.8 Hz. 
       
      My questions are as follows:
      Is the box too large? I commonly see Jacob recommending 1-1.25 cubes for a ported SA-10.
      Should I keep the 4" aero? It gives 9" of port per cube (high end of the spectrum for an aero)
      Or go with a 3", or just go slot port... If I go slot, what kind of port area should I use?
      Lastly, is that a good tuning? I would like an F3 around 28Hz. 
       
      Thank you for all your help, as always.

      This topic is really for my new upcoming build which will be two Sundown Audio SA-12s on a Hifonics BRX 2400.1D sealed off from the trunk.  The box is currently being built by Dave The Box Guy, it will have three different tunings with interchangeable ports (20Hz/28Hz/45Hz).  For now, while I sit and wait, I am going to post my current set up just to show you all some of the work I have done so far.   I don't have all the pictures since some things were done a little while ago such as, deadening, changing my door speakers, wiring etc. but I will eventually tear some things off and show you how I installed everything.  Here it is....
       
       
      Current build:
      Head unit: Kenwood KDC-X995 w/ iPad Mini
      Equalizer: Clarion EQS746
      Mids/Highs: 4 Infinity Kappa 62.9I (wanted to keep stock look so they are in the stock location of the doors)
      Subwoofer:  1 15" Sundown Zv3 D2
      3.3ft3 enclosure tuned to 33hz (Sub Up, Port to the side)
      Mids/Highs amp:  Hifonics Zeus ZXi80.4
      Subwoofer amp:  Hifonics Brutus BRX 2400.1D
      Electrical:  Stock 150A alternator, XS Power D6500, BIG 3 to come soon
      Deadener:  Second Skin Damplifier
      ***The only thing that will change with the new build will be the sub stage which is listed in the first paragraph, everything will most likely stay the same... for now lol***
       
       
      This isn't my actual car, but this is what it looks like completely stock on the outside..
       

       
      Here are some pictures of my car after some cheap mods!  Tint is %30 and hubcaps plasti-dipped!
       

       

       

       
      Tinting my tail lights soon!  Don't have a pic before the de-badge so here is the after..  If you can tell I replaced the stock antenna with a "shorty"
       

       
      On to XS POWER, haven't done the BIG 3 yet but that is on the list of things to do.. Here is the stock battery under the hood.  I already ran the 1/0 gauge wire through and plan on shortening the wire to the fuse soon as well.  I will try and get pics of how I ran it later..
       

       

       
      Look how small the stock battery is compared to the XS Power D6500!!
       

       
      Finally installed, it was a b**** to get into that small space.
