I have no clue where to go with my system, keep being told to peice a system together then told to go with a powered sub. I want a single 10 or possibly 8 if there is a good one that will perform well in a small sealed enclosure installed in the trunk. I am not looking for big bass, really don't even want to feel it inside the car, as long as it is heard. What do you recommed? I don't have the amp, so I will be getting one after I choose a sub. Thanks for any recommendations.
