New Speaker/head unit install in 86 CJ-7

Hey everyone, I purchased a new radio head unit thing, some marine speakers and a marine amplifier for my CJ. Upon installing everything and wiring it to what the diagrams for everything show to be correct I cannot for the life of me figure out why I can't get substantial sound to come from the speakers.

I've double checked my wiring for everything but I cant get it to work right. There is music that comes out but its very faint even will the amplifier and when I turn the output volume all the way up on both the head unit and the amplifier the music becomes more audible but its very distorted.

Are the speakers/amp/head all of the same Ohm rating (4 Ohm or 8 Ohm?). Most mobile units will be 4 Ohm but there are exceptions. A mismatch can behave much like you have described.

Are you running everything thru the amp?

What type of RCA cords did you use? Did you use pre-amp outputs, Or did you use line level inputs

Do you have the gain on the amp up?

What make HU, speakers, and amp? What are the ratings?

2 Speakers only? Did you wire them front or rear? Do you have it faded?
