OK, here is my story of how to install saddlebag speakers on your 2011 FLHXSE2,
First off YOU CAN make sb speakers work on your 2011 SESG, I will post some pictures of the wiring you will need and I do have someone that will build this harness for you. You will also need to have your dealer do the software download for your HK radio, tell him you want the REAR SPEAKERS ACTIVATED, your dealer will then look at you and say, you can not put SB speakers on that bike. LOL, ( the software is free when you purchase the SB speakers from Harley, fine print you may be charged labor for this). Also you will need to have your dealer activate the FADER CONTROL at the same time. Now that you have done all of the above, install your new lids, speakers, and run your speaker harness inside your fairing, ( good idea to mark the speaker leads LEFT / RIGHT ) before you run into fairing. Now with that being said, the harness you will need will plug directly into the speaker harness that came with the HD 2ohm SB speaker kit, again pictures will show you the extra harness you need to hook up to the HK radio. You will NOT need another amp at this time to make your SB speakers work, they will work and you can use your fader control to give more to SB speakers or more to fairing speakers. Now keep in mind you are taking away from the factory HD amp when you do this type of install, this will not hurt your system it just decreases the power you had, because you are powering 8 speakers now and not the factory 6. The above is what I did with my 2011 FLHXSE2, and like i said it DOES WORK. Now I will tell you that the sb speakers are alittle hard to hear when riding, this is when you would use the FADER CONTROL i told you to have activated at your dealer, this will vary with your individual bike exhaust, wind, and how good your ears are, mine are not that good. PART 2. After trying this set up for a few rides I decided to install the Hogtunes 70.2 amp in my fairing, ( i did not want to install amp in my saddlebag due to lost storage space) the HT amp was a perfect fit for inside the fairing. You will also need the Hogtunes 2-Channel Amp mounting kit ( part # 2CHSP 4405-0234 ) the mounting of this plate is easy to do, and the amp mounts perfect to plate with the included Velcro that is included with the purchase of the HT 70.2 amp. Now keep in mind that when I installed this HT 70.2 amp i DID NOT cut any factory wires, I used the HT 70.2 amp to power ONLY the Saddlebag speakers. All factory speakers are still powered by the HD factory amp.
Now Part 3. After completed install and wiring hook up, I powered up the system, what a difference the extra amp made! Now with my fader control set to the middle of the bar graph, I hear what i feel is equal sound from Fairing and Saddlebag, I did set the switch on the amp for +3db personnel preference, you can adjust this feature before you reinstall your fairing. If you have any mechanical ability you can do this total install on your own. For me this is the perfect fit, with a low budget price when all is complete, very happy with the sound now. In closing I am sure some of you are happy with this post, some are confused, some don't care. But this forum is how i found help on hooking up my system from START TO FINISH. 99.9% of my help came from TIF2 he has always answered every question that i sent his way.
