Aloha!

I have a MRV-M500 Alpine amp with speaker level inputs that i want to utilize. I have a few questions about the harness.

1. The amp has 3 connectors - in the diagram they are A,B,and C. What harness does what? Like Is one harness used for taking the input from the head unit, one for output to all the speaker and one for navigation?
2. What the hell is RR L on the diagram? I always saw RR as "Rear Right" but i guess that acronym isnt the same in this case?
3. I hooked up the aftermarket sub with a LOC using Connector B #14 and #2 - but i also see on Connector A, #7 and #8 are also SUB +/- as well. Which one is best to use? I guess this question would make more sense once someone answers #1 lol
4. The factory amp has a connector on top - is that the ANC? I attached a pic for reference
5. My speaker level input harness has the regular 4 speaker location (FR, RR, FL, FR) - which wires in the amp would be best to use in this case? Again, this will prob be answered once i know wtf the amp harness's do

Thanks guys! Sometimes my thought process is a bit wacky and these questions may not even make any sense except to me. Let me know lol

 

bump! I was trying to do this today, so might just start splicing in wiring and see where it gets me :/

 

ok cool.....in case anyone needs help with this - i guess ill post my findings....

I ended up using 2 and 7 connector B, 1 and 6 connector B - the sound still feels a bit off, like not all frequencies are being passed to the AMP. Id ask for help on this but...judging from above no one would help lmfao

 

Unfortunately, not many people have messed with the audio system on this car, and those that have were very frustrated

 

Man I need help too if u find the way let me know if not I will pay to expert in sound systems cuz I want to add 2 Kickers 15" in the trunk and upgrade all the full range speakers
