the current system in my truck is crap i was 16 when i bought it and now ive decided its time to upgrade. i drive a 2000 gmc sierra extended cab and i dont really want to give up that back seat. i found some alpine type-r 12's for a decent price but now im not sure if i can get a box built that will allow the 7 3/4" mounting death under the seat. does anyone know if they will fit? should i go to 10in type-r or should i just try to find another type of sub. im open to any suggestions but i do want to stay around 1000 rms thanks
