Fantastic Speakers and great seller

I have a classic muscle car and replaced a set of Pioneers I had for about a almost two years with these Infinity.......WOW what a difference, I couldn't praise these enough. They effortlessly deliver a smooth powerful sound like no other 6x9 I've ever had and would definitely recommend these to anyone. An excellent speaker and awesome seller.....
