personally I wouldnt use either, but they are definately cheap. What kind of budget do you have and maybe we can find you something a little better. You get what you pay for, and honestly I doubt that either of those will last a year.

that amp will only put out about 120 wrms, if that much, and it doesnt say its bridgable.

I wouldnt give that sub anymore than 100wrms and thats with a clean, non-clipped signal.

again, what kind of budget do you have and maybe we can get you something a little better.
