Question speaker grounds/grounding

i have seen threads for floating/common grounds. unfortunately i have not come across the answer i want to find through all the threads i have read here and elsewhere. enough to actually answer my question i should say.

i am using 12 pin molex quick connects for wiring on my system needing 11 pins total
issue: having to run 2 - 7 conductors vs. 1 - 7 conductor
connections needed:
4 spkr +
4 spkr -

with common ground system, can i run the 4 spkr - wires and power ground all in one lead as follows?

#1 FR +
#2 FL +
#3 RR +
#4 RL +
#5 IGN
#6 B+
#7 4 spkr - and power ground

i do not want to tear my equipment/truck apart to only find out it will not work in the first place. i know common grounds are able to use chassis ground contact points with possible noise. i use all d-blocks for grounds, NO CHASSIS!!! with possible g-loops on common ground systems, will my 7th wire above creat a loop for noise? i am running spkears wires into a line convertor. any simple help is very much appreciated.

Are you installing a head unit made after 1990? If so, you do not want to attempt common or chassis speaker negative connections.

Old cars, mainly Fords, used chassis or common speaker negative connections. If you have one of these vehicles, run all new speaker wires.
