hey guys. i have a JL 10" Subwoofer and im on the search for a amp. now i have a buddy willing to sell me a Rockford Fosgate 200watt for $30..that seems like a great deal for a nice little amp, but my question is. is the amp too little, i have friends telling me i need bigger, and i have people telling me itll be fine...what do you guys think? is 200watts enough to power a 10inch sub?
