Good morning together, with my Corsa B both speakers are in the front of the doors, which to fetch from the junkyard does not bring anything because they hold again only 3 months. Did I look out at Ebay…sometimes the following.http://cgi.ebay.de/…/390279215126?…can you install these well? Does someone know about it…and how do I get the tweeter built in? Do these listen well? Do I have to build in the back also new ones then rather? ++ Have a subwoofer with in already. Gruss jens
