2017 Tundra CM non/jbl Dash speakers not working after installing aftermarket amp.

Hello all,
I just installed a picasso nano 5 channel amp im my 2017 cm. Non/jbl with center dash speaker. After installing, the dash speakers (3) and the rear door tweeters are not putting out any sound. I installed the amp using high level inputs. Door speakers and sub sound good enough for me. Bugging the crap out of me that the dash speakers and rear door tweeters stopped working. I may want them unplugged anyway, but I wanted to try it first.
Information I found showed the dash speakers and rear door tweeters powered directly off of the head unit.
Has any one else had am issue similar to this?
Any help would be greatly appreciated!

 

Just speaking for myself here and I am no audio guy just a DIY one lol. Anyways, I powered my center dash along with the corner dash speakers to the the door speakers and tweeters. I split the center wiring to go one on each side for wiring and sounds pretty good to me. I rewired everything and all are powered by my 5 channel amp. Im not using any of the factory connections so all are wired to the amp and then from the amp hooked up to the HU through the rca’s input/outputs.
