4 channel LOC

Hello audio experts I need your advice.
I am a newb at audio installs and just learning about amps and speaker systems.
I have a 2018 Tacoma 7inch non jbl stock head unit and i upgraded the speakers and it sounds great but you know how it goes. I am now thinking of adding a 50w amp to the stock head unit.
I don't want to replace the factory head unit.
I bought the Subaru tweeters and Upgraded the front and rear speakers to the Kicker 47KSC6504 and the 47KSC6904 series, I plan on not running a Sub. My question is I see a lot of 2 channel harnesses available but I don't see any 4 channel. I want to be plug and play as much as possible I don't want to cut the factory harness. The amp I am looking at is the Kicker 47KEY200.4. it says it will accept high current amp signal so can i just feed the stock amp signal directly into it? or do I need some type of convertor? I am having trouble locating a harness for plug and play. Any advice would be greatly appreciated.

Thanks, a lot of information there.
I'm looking to buy a harness. Too much to deal with there for me.

 

Like we’re not here to just regurgitate already available information for passers by on demand. There’s the link, it’s all there.

You have to put in some effort as well you know. When you do, people are more willing to help you out.

 

Ok then I’ll rip the bandaid off.

there’s no plug-and-play harness to do what you want to do. Sorry

 

Like you don't need to answer if your busy. It's not like i have time to read through tons of threads either.
Just looking to buy a harness, no big deal Mac daddy.
