That will depend greatly on what type of amplifier you will be running the components on. Without knowing what amp configuration you are planning to run it is impossible to suggest what type of components you should use. Speakers and amplifiers should be chosen together to match the system up. You shouldn't just choose a speaker then find an amp to match. When choosing the power you will need for the components you should figure about 50% of the power that you will be running on the subwoofer.
