TM400x4ad question - 2/4 channel option
so reading through the manual (yeah I probably should have done this BEFORE I installed 
) I came across this little tidbit:
So am I reading this correctly that because I have a stock 6.5 head unit and only front output, I'd keep this in 2 channel mode but use the front AND rear outputs from the amp (assuming I'm running 2 sets of speakers, fairing and lowers)? This way I'll get the full power to each set of speakers using all 4 channels?
Sorry, still learning as you can see so school me if I'm wrong please.
) I came across this little tidbit:
2/4 Channel Switch
Setting this switch to the 2CH. position, switches the inputs to
a 2-channel mode, allowing connection to only the front inputs
with a 4-channel output.
Output controls function the same as if the amplifier was in
4-channel mode.
All ACTIVE inputs must have RCA jacks connected.
Switch in 2CH. position,ACTIVE - Front channel inputs only.
Switch in 4CH. position,ACTIVE - All Front and Rear channel inputs.
NOTE: When connecting to the 4-Channel inputs, be sure to route both
front and rear RCA cables tightly together.

forgot to mention, I was going to use "Y" splitters from the Biketronics Line Leveler. SO I can just eliminate the "Y"'s right? or is there a benefit to having the 4 inputs even though I have a stock HU?

Lol. . . No jeopardy question bro. All you need is two line levelers for the 4 channel amp. Run the fairing speakers on the front channel and the lowers on the rear channel. You only need Y splitters if you add another amp. 2 channels = 2 speakers.

Am I reading that wrong?
or do I actually have 4 channels coming out of my head unit somewhere in that harness?

all I need to know now is is it ok for me to run the stock 2 channel outpt from the HU to the Line Leveler, then into the amp (as only 2 channels) the utilizing the amps ability to output 4 channels from that 2 channel input
or
buy another line leveler, split the harness and use the rear blue wires to input 4 channels into the amp?
