in the instructions for this kit, it mentions the saddle bag for the location of the "secondary amplifier" but since this is a trike, where is that piece supposed to go? thanks in advance

 

I can't help with your question.
i would think it would go in the bottom trunk.
i did see on the site they have a speaker kit that mounts on the trike body close to the passenger. That would be cool for a flrt

 

I had the dealer install the boom audio on our 2013. The amp is toward the front under the tour pak. There was another option of placing on the front outside of trunk, I did not like that option.
