all i can tell you is its a 2ohm dual voice coil sub, as for power handling i am guessing around 75 watts rms, i have an after market sub& and didnt even bother selling my stock sub incase one day i decide to hook it back up again or sell the car
yea, i honestly wouldn't even bother wasting your time on putting a good sub into a plastic box, check the specs on your sub for the air space requirement like PursuitGT mentioned. if your worried about room in your trunk look into a small sealed or even ported mdf box.
1 cubic foot is what my sub requires. The box I had it in is not much bigger than the stock box if any. I made the spacer and test the sub out, sounds the same as in the old box. Going to seal it and see what kind of results I get, if it sounds like ass then Ill take it back and knowing at least I tried.
