round versus oval there is A HUGE difference & shape DOES mater... an oval-cone cannot move in a linear fashion... especially when you are talking about low frequency/bass notes.. which is why anyone would go to the 6x9 over the 6x8/5x7....

www.onlinecarstereo.com if you cannot find a good round component set (5.25 or 6.5 & tweet) for your budget.. then get some kraco's @ autozone & call it a day... They have MTX, Kicker, Rockford Fosgate, lots of great brands.. on close outs & final mark downs.. take some time
