Many people arn't fond of RF subs now adays. In choosing a subwoofer its best to figure out what you expect from it. Do you want it to be loud, or have nice lows. How large of a sub are you wanting to run? A custom built enclosure is key for optimum potential so you'll have to think of how much room you have for the needed enclosure. Then you have to think of how much you are looking to invest into a quality amp that will put out the true needed RMS for the sub you decide on.
