http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1943895960I bought some off these tweeters off of ebay for under $10, and I think they are well worth the money. They fit perfect in the dash and its cake to install. They may not be as good as those Polks, but in my opinion...it's just tweeters.
Keepin it clean!!
