Ok so my front passenger side factory speakers crapped out on me and im pretty sure that the rear drivers side speakers are on their way out also. I dont want to spend 200-300 for one pair of speakers so what about something like these? http://cgi.ebay.com/ws/eBayISAPI.dl...Category=14936&_trkparms=algo=LVI&its=I&otn=2 Also, cant I replace the factory 6x9's with those also? I have to buy two sets of speakers and want to keep it around 300-350 max for both sets. Thanks.
