upgrading my system. ill be using this box http://caraudiofactory.com/451x12-sp...box-p-141.html

and i am torn between either the 12w3 jl http://www.woofersetc.com/p5203/12W3...-Subwoofer.htm or the 12 kicker cvr http://www.woofersetc.com/p5318/07CV...-Subwoofer.htm.

as for an amp i was looking at either a hifonics or an alpine both are around the same price. and input on the system would be greatly appreciated! thanks in advance

 

Go with the Kicker for the sub... I have and would recommend the Alpine Amp... It's a very reliable product... Small footprint, low heat output, and plenty of power... I have two...
