My friend has these in the back of his Focus running off the deck, with matching RSD components up front amp'd. The coaxials sound very good....I was very impressed with the smoothness of them compared to my JBL coaxials I have in the back on my car. I think they are a great buy for the $$, just the same as the components //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif He is a member on here, maybe he will chime in...
