Anyone use PAC APH-TY01 harness: Uses stock speaker wire with aftermarket amp

I plan on running a Rockford Fosgate R600X5 Prime 5-Channel Amplifier that puts out 50 Watts x 4 + 200 Watts x 1 @ 4-Ohm to my aftermarket speakers and 8" Pioneer sub.
I have read that anything 50W and under should be ok to utilize stock speaker wire.

QUESTION:
I can't find any reviews or write ups from people who have use the PAC APH-TY01 harness.

Anyone out there familiar or have experience (positive or negative) with these harnesses or this setup?

Seems pretty easy to just plug it in to the factory speaker harnesses you pulled from the stock JBL amp and wire the harness to the aftermarket amp.

I called PAC and they confirmed it should be that simple and I could remove my stock JBL amp which in turn will free up space behind the rear passenger seat for aftermarket subwoofer box and amp.

 

any luck? I’m about to buy one also..
