Brian and I opened up my trunk and looked at my rear speakers. Apparently they're not stock. After two years with this car I just now looked at them... haha The previous owner had put 6x9 140w Blaupunkts in the rear. These speakers seem ok, but I had already purchased 6 1/2 Kenwood 150w speakers for the back. Whats your opinion on both brands as per their sizes? I'm thinking of just replacing them anyway since I already spent the money, but I dunno. Might be slightly less work.
