Well they will fit and you do not have to rewire the whole system. You can just replace the door woofer with the alpine one and also replace the factory tweeter with the Alpine tweeter. many people have done this hack with the tweeter by carefully removing the stock tweeter and putting the after market on the factory mounting plate by gluing etc. Now, the drawback to this is the frequencies that is going to be sent to the new speakers by the factory amp may not be a the same frequencies as recommended or designed by Alpine. A good installer can put capacitors/passive cross overs to compensate for the proper frequency as recommend by the new speakers. (they can also utilize the crossover that comes with the Alpine)
