Car Stereos: amps & subs, infinity reference, watt amp

Question
hi there, i just bought a new car and it came with a Kenwood 200 watt amp but no subs so the question is what kind of subwoofer should i get that would be safe(no fires) and hit nice and clear?

Thanks

Answer
josh, sorry for the delay.  I would recomomend my top choices of JL Audio or Infinity reference subs.  Either one will handle the power and sound very nice.  Be sure and use a sealed box just big enough to meet the specs of the sub you are using, and that will keep the bass tight and punch.  Hope this helps, Scott
