Great Product

I bought 2 pair of these speakers from a local car audio shop for 200 installed but then i came to this website and saw the going for 70 a pair i wish i would of came here first. They sound great and have really clear highs and produce great bass. they have the button them to control the tweeters which is great. I've yet to get an amp for them but that will come next.
