Thanks, for the response, have seeen at leat 6 reviews on other Mustang forums that were not favorable on the Shelby/Kicker subs if you use the stock amps. Am still doing mye research, so thanks again for the input.
Have you replaced yours with the Shelby/Kicker subs and if so, did you retain the stock amps?
Yeah I would imagine there would be crappy reviews of the kicker speakers if you don't upgrade the amp. Amps do a LOT for the sound. I wouldn't change my speakers without doing an amp. I don't have the speakers/amp upgrade on my mustang, but I have had Kicker equipment before, among others, and it was top notch.
