can anybody make me a set of plans for a ported enclosure for 2 12" subs. i have all the specs from the manufacturer and can email them to you. i had 4 12's in my car but a got another car so i'm splitting up my system between to cars and now i have the room to make a big bad *** box to make my subs wang ****in' hard. the subs are swiss audio spl1290's 4ohm DVC 700 rms and currently have memphis mc1000d amp pushin 1100@1 ohm. the car is an 81 cutlass supreme, if anyone offers, i'll measure the trunk for dimensions.
