Just to clarify for the folks who aren't intuitive with wiring/electronics ....
In order to eliminate the common ground, you'll need to run 8 wires copper stranded wires from the HU and splice them into the output of the amplifier, bypassing the amp. 1 pair each for the FL., FR., RL, RR door speaker combinations.
This means you'll need to remove the speaker connections between the HU and any wiring harness you received to connect to your OEM wiring going to the amp. You'll run 8 wires (or 4 pairs, which is more common) down to the location of your amp, meaning you'll probably want 5+ feet of wire extensions (40ft. total if you're running individual wires). Consult your EWD diagram as to the color combos to connect the appropriate wiring color combos between the head unit and speakers to ensure you don't reverse polarity. I'm sure the color combos can be found in various threads in this forum using the search function.
