Speaker (high) level amp install question/help

I have a 2013 Honda Civic LX and I am doing my first car audio install with a amp.

Hardware
JBL p660C components
JL audio cs110-wxv2 10" inclosed sub
PPI i320.4 320 watt x 4 channel amp
8 gauge EFX amp kit
14 gauge RCA speaker wire
mdf speaker rings
sealant

I have 3 questions:

1) The amp has speaker level inputs for front speaker channel (amp) which is wired up through a 5 wire input harness (L) (+ - G - +) (R) and another for the rear speaker channel (amp) with another 5 wire input harness labeled>> (L) (+ - G - +) (R). I was originally going to wire the front speaker channel (amp) by tapping into the Left rear speaker wire, and then splitting the wire to feed both the L/R side of the front speaker channel (amp). Then with the rear speaker channel (amp), I was going to tap into the Right rear speaker wire and split it the same way to L/R sides for audio signal to my sub (bridged). After thinking about it I was unsure if this would be the best setup due to how music is recorded (which i know little about). So my question would be, would this type of wiring effect the ability to hear music in stereo?

2) The PPI i320.4 has speaker level inputs with "signal sensing for automatic turn on"...I assumed I did not need a remote turn on wire. So far I have tried wiring in the front speaker channel (amp) via tapping into the L/R rear speakers (to just see if it would turn on) with no luck. Each rear speaker wire is producing around .01 volts. Is there a minimal voltage that most amps like this need to turn on? PPI's website, customer service and manuals are lacking to say the least. The amp does turn on when I use a hot wire from one of the rear speakers as a remote turn on REM IN/REM OUT) and the other as a speaker level input.

3) If I have to tap into a hot wire for a remote turn on, which is the easiest in these cars (ignition, lighter, fuel pump....ect)?

Thank you for any help!!

First off if your wiring the amp to give you sound in the front off high inputsxl,then you use the front outputs for the front.Not the rear.
Second I'm confused as to you saying your using the the output for the power of the amp?

Thanks Eff!! Afraid you were going to say that about the fronts

For the front outputs, if I don't want to cut the original wiring do I go back through the door and connect audio cable with a harness or am I able to use something like tap splices (not sure if they would degrade audio signal) from under the dash?

I know very little about stereo, 5.1, 7.1...ect, signals. Does the front channels in a basic "stereo" (I know 5.1 and 7.1 are much different) have a different audio signal output, compared to the rear?

"Second I'm confused as to you saying your using the the output for the power of the amp?"
typo>> should be>> for subwoofer audio signal. There is a overlap in how I am thinking about the factory rear audio wires since they are also suppose to be a REM IN switch, besides sending the audio signal

Your on the right track.
I would de pin the harness outputs at the radio and ripin the hi input there.
The amp is so small you might be able to tuck it back there.
When you tried using the high sense was everything plugged in with music playing.?
No worries about the surround sound processing for various reasons but in short your running a 2.1 so that's more than enough in a car.
If I missed Something pm me
