Hey guys I recently baught a sound stream rub1.2500 for 300 with 1 year warranty. And might I say this is a great amp. I have it hooked up to a 12" t2 taking up my rear seat and this things slams! I wanted to buy another t2 and my a box that takes up my whole trunk so each sub would get roughly 2.3 cubic feet of air space nd tune it to 30 hz. What do u guys think?
