Arrow Audio Experts- Amp Install

I've been researching for the past couple days on building up the sound system on my rig, and I think I'm finally ready to tackle it...Just had another question I couldn't seem to find the answer to.
I have a '14 JKU with the premium Alpine sound.

Here is the thread I've been working off of:

I want to add an amp and sub to my 2014 wrangler rubicon

Here is my question:
I had planned to use an LC6i just like many write-ups have stated, but the amp I'm using (JL XD700/5) can take high-level speaker inputs, therefore eliminating the need for an external LOC.
So, instead of wiring the inputs to the LC6i, can I just wire them straight to my amp in the same order? Would it look any different than what it stated in the write up (front woofers to channel 1 directly on my amp, front tweeters to channel 2 directly on my amp, then sub to channel 3 directly on my amp)?
JL makes speaker wire to RCA adapters I'd be using to make these connections by the way.

From what I have read online, using an LOC would be an unnecessary step with the amp I have. Do you agree?
Also, do I not need to feed the soundbar speaker signals into the input of the amp?

Thanks for all the help on this forum. Now that I have a grasp on what needs to be done, I can save a ton of money on shop labor.

close...for that amp ch 1 and 2 are your front right and left. 3 and 4 are rear right and left. there is a connection marked mono sub. that is where the sub inputs would go.

I have the 6i in my setup. What the 6i will give you that the amp alone will not (I think the JL does not have summing) is summing. That is to say that the factory left channel has the bass cut out of it (which is routed to the sub channel). The problem is that the sub channel is x-over at a higher freq than you want.
THe 6i will take the input from the sub, mids, and tweets (the mids and tweets are the same in the wrangler - frequency wise - as the tweet has a built in low pass coil so it gets a full range signal) and sum it all together to the outputs.
My advise is try it with just the amp, it is free, then if you don't like sound add the 6i later.

Got it, so you would still use an LOC just for the summing feature?

Also, where is the easiest place to get signal from the OEM amp and back to the speakers? Would you cut the output harness at the amp and make connections there? Or extend factory speaker wires to the LOC and then back to the speakers from the amp outputs?

I purchased the Chrystler plugs and plugged them into the connections next to the speakers.. then ran the wires all the way back to my 7i.. THEN ran RCAs to my amps from the 7i.. THEN ran speaker wire all the way back to the speakers again.
I am NOT AT ALL certain that is the best way.. but if I sell the jeep I have not cut a single wire.
There are write-ups about which wires to cut at the factory amp for signal, that would probably be the cleanest solution, I would think.
