I currently have the Infinity Reference components in my car and one woofer just blew. I can get basically the same thing (just 4 years newer), new, for about $60 on eBay. But I was thinking of getting the Kappa components because they handle more wattage. That'll cost me about $130 shipped on eBay (retail $299 or so?)

Anyone have any recommendations on something better for the same money? I'm guessing any $300 component system can be had for about the same price on eBay. I'm clueless about car audio brands. I don't really see any reason to stay loyal to Infinity except that I have 2-way Infinitys in the rear doors.
