Installing 5 channel amp in 21 non JBL

I recently picked up a 2021 Offroad without the JBL system. I have replaced all of the door speakers and have a 10" TW3 JL audio that is not hooked up yet. I also have a LC6i that i assume is the easiest way to get low level inputs to the amp? What would be the easiest way to get a signal from the raio to the LC6i, use one of these tee harness cut in half?

Also, any recommendations on a 5 channel that will not break the bank?Thanks for the help.

 

Yep. Cut that in half and get a roll of speed wire (multi-conductor cable) and build yourself a t-harness

lots of good 5ch amps. Every major brand has an entry option for under $500, and then a nicer option. There’s an awesome price right now on the Audio Control D5.1300 and that gets you a built-in DSP. Very helpful since you’ve keeping the factory head unit. Allows you to actually tune it properly, add time alignment, etc.

Many amps will not need the lc6i these days, but a few still will. Depends on what you get. If returning it allows you to spend more money on the amp, that’s what I would do.
