got my system all set up now. premier 860 deck, alpine 400w 4ch amp bridged to a set of focal kp 6.5 components. 2 kenwood 1000w amps. i have type r 12's but they will not fit. i just need a box first and i'll get a set of 10's that'll match the box's specs after. for extended cab the subthump one for dual 10's looks best but they dont ship to canada. i need a good box i can get here. and more specifically in edmonton alberta if anyone knows of a good place to get one. ive seen the bassworx one at jb's but it doenst look too appealing to me.
