im currently building my stereo. i decieded i want a w7. what one would be the better amp and why for my sub. either the alpine 1000.1 or the jl audio 1000.1. the alpine is cheaper id prefer to go with it but if the jl audio amp is better than i guess i can be convinced to spend the extra $$

you wont hear or feel a difference, go for price/application/warranty....
I have the JL 1000/1 and love it, but if I was buying authorized and paying anywhere near retail I would have probably chose the PDX.
