I am losing my mind trying to figure out where I went wrong, any help would be appreciated.

The amp is under the back left seat.
I am using my stock head unit.
I went off of the radio wiring harness to connect my speakers and amp through.
I ran my constant right to the battery with a 50 amp inline.
I have a good ground to the back seat bolt
I still have to figure out which wire to the radio is for the accessory but I used a constant to test power. (if anyone knows which stereo wire in an 04 harness is the accessory, please let me know.

problem, the front speakers have next to no volume and the rears have nothing but distortion,
