    Cheap And Cheesy
    I have had a lot of 6x9s over the years... These are very nice. Well made all the solder joints look great. good solid feel and clean design. These are 4 ohm 200 watts and barely fit in the rear doors of my 2013 dodge dart! Was wondering for a second... I doubt dodge paid a dollar apiece for the ones that were in the doors... so cheesy and cheap! Going to buy another set for the front doors. Can't wait till I hook them up to my amp, currently on deck power and they sound way better then the stock ones.
