what you think?

 

pac also makes the harness that give a little better sound quality as the axxess one doesn't sound that great..

 

I can't get sound from my aftermarket radio.

 

klb Welcome to the forum

Lets start with some basics...
Is this a newly installed unit?
Did it work before you replaced it?
Have you check and double checked all fuses?
Do you get any sound even speaker pop when turning it on?
Is there an aftermarket amp installed or just head unit to speakers?
Are the installed speakers rated for the head unit.. 2ohm, 4ohm 8ohm etc...
What was replaced, radio only, speakers and radio and wiring...
