You have a couple of options. From what I understand, you have the signal going from head unit to LOC to amplifier. Now you need to go from amplifier to 4 corners? It sounds more complicated in words than it is in actual practice.
Option 1 - replace T-Harness with a loop-back harness. It...
Without knowing what amp you are using, the answer is yes. Do you really want to hear the back speakers? Most of the time the back speakers will be used just to round out the sound and give some fill. I also use the back speakers to help out my backseat passengers when we have the top off on...
It depends on what you want to do. What I mean is, do you want to control each speaker independently? You can use a 6-channel amp and each speaker will have its own power, crossover, etc. Probably overkill. The easiest thing to do is just buy a pre-made harness and amp for a plug and play...
I like your choices for components:

I also love seeing something other than Kicker Key amps.
Those are both good options and good value for mono amps. I used a Kicker CXA mono for one of my other cars. And both of those are pushing enough power at 2 ohms to be useful in a Bronco.
It should be a good match from the specs. If you want easy and cheap, Kicker Key amps are a good choice. Especially if you don't want to do any tuning or optimization yourself. Another question is how much bass do you want? With the top down at 70mph, do you want to still hear the bass?
I drilled the capable bumper to mount a bar. It's pretty easy, but you definitely want to remove the bumper first. Also very easy.

You don't need 2 amps. You do need to amplify at least the front speakers and a subwoofer. As someone else said, get a 5-channel amp and you can amplify all your speakers and add a subwoofer. You can get a good one for $400-$500 that will put out more than enough clean power. You can get a...
