    I have two kicker F12A's and need a box and amp for them...

    Bottom of pg 3 has their specs
    http://www.kicker.com/06/tech-support/manuals/archive-manuals/Separates%20Series%20Competition%20and%20Freeair%20Drivers.pdf


    Says their cubic foot volume is 5.15-5.20CuFt... So I need 10.3-10.4 CuFt for 2? :)eek3: this is going in a '00 mustang convertible)

    Now, I currently have a 3.0 CuFT sealed box for both subs with no seperating baffle.. I am guessing this is going to sound pretty shitty. But its about the biggest thing that will fit in my trunk. Should I really strive to get a bigger box? Should I do definitely do ported since its a free air sub?



    For an amp selection.. I put one of them on a 222w amp and it hit harder than the 10" that was on it, but it was in a pretty small box and just didnt sound that great. The spec sheet says 400w for vented, 250w for free air.. Would a 600w sony xplod be alright or should I step up to 1000w?

    TIA :cool:

    400-500 should be more than plenty for kicker free airs.

    why are you putting infinite baffle subs in a box?

    because i tried free-mounting them like others said and they hit, or rather DONT hit, like any other sub does outside of a box. i put one in a cramped box and hits hard like it should.

    That's because your install sucked :hsugh: You need a COMPLETE seal between the front of the sub (in your cabin) and the back of the sub (in your trunk or wherever else). That means no open speaker holes, holes in the rear deck, wiring holes - that means no kinda-sorta closed off with some baffle board or something. That means SEALED. A little leak goes a long way towards completely ruining your bottom end. You can make IB slam, and it's the best possible case for efficiency and overall sound quality if done right. Try it again.

    Correct, a completely separated front/back wave...
