What??? fusion?? Their backing is made out of aluminum, the speaker magnets are weak, i dont see how their that good.
Now, for quality and price, sony xplod has some really good stuff (player and speaker wise). MTX speakers are nice.
for amps, rockford fosgate, the best amps you could get for the money ( they under-rate their amps, and will usually put out an extra 20 watts), sonys are very good too.
and for subs, JL's, the best subs you can get for the money. Sonys are good, jackhammers,
