I have replaced them with these 22 year old 5-1/4" rear speakers. I am installing them in a regular location but with a 6x9 adaptor. For the price they just sound great. Sure you can get better sound than these speakers but it will cost you more. I didn't want to put a lot of money on my son's 22 year old BMW, the speaker grilles were too bulky so I'll stick with the stock grille.
