Bought these to drive off HU and was not happy. Decided to put in rear and put CDT coax in front and drive with Kenwood 4 ch. amp. Well once I drove them with amp I discovered why I did not like running off HU. They are power hungry and once I had enough power to them combined with CDT's in front they sound unreal! I have always liked JBL and continue to like them. Just make sure you drive these with amp and give them the juice they need. If you do this they will perform.
