I replaced the Shaker 500 door and rear shelf speakers in my 2011 Premium with Pioneer TS A6885 R 4-way speakers off Amazon for $41.93 a Pair. Left the stock subwoofers. No other sound system mods. It sounds like a concert hall now. I'd suggest starting with the door and rear speakers first prior to any head unit, amp or subwoofer mods.
Thank all of you. You're help is greatly appreciated.
