Yes, I bought a shaker 1000 sub and amp off eBay for 250.00 with shipping. Very easy to wire in to the head unit for a factory setup. Just need to buy the pigtail adapter to plug into the amp and then run the mute/enable, pre amp + and - to the head unit and tap off the same three connections on the eight pin plug on the back of the head unit that go to the door sub amp. It's the same circuit inside the head unit that feeds the door and trunk sub amp, it will always power on with the radio. If you want the menu option to mute the trunk sub, the dealer would need to program the ACM with the shaker 1000 option. You ground the amp in the trunk and just run a fused power feed directly to the battery and your done. Took me about an hour to mount the trunk sub and wiring.
