Just replaced mine by an installer. As you may or may not know, Dealer has stock 2 ohm replacement for $190.00. I had taken out the rear sub cover & removed the 4 bolts for replacement. Replaced it with a Kicker 8" Mid-bass RMB8. It has a very slim depth. Installer had to grind down the sub bracket (although there are screws attaching the sub to bracket, it is a SOLID piece) Had to rip the old sub off bracket & screw in the new one. Not only that but I had to purchase an amp to power the 4 ohm sub since the stock amp runs @ 2 ohms. Good luck ! ! !
