So i Ride a 2017 Road Glide Ultra, Current setup is Sony AX100, PA RZ4-2000D, Hertz MPX165.3(front), and Alpine Type R(tour pack).

The next phase will be installing a Rockford DSP, Skar SK-M4004D, Skar NPX 8-4, and Skar VX1-ST into the saddle bag lids.

My question comes from when the tour pack is removed. I Would love to run the RZ4-2000D bridged to the two MPX165.3 and feed them more power to balance the sound of the front stage and rear when the pack is removed. Ive come up with the attached diagram to run a switch that would allow the switching between the two connection types. I figure worse case I can tone them down with the DSP if by some slim chance they are to loud(doubt it)

Thoughts?
