Going through the amp. I don't have the harness to plug the RCAs into the dd1
all you do is plug the RCA into the DD-1, you have an aftermarket deck. I dont see why you are doing it through the amp.
Ohhh ok. Didn't realize that was how it's done. But either way, I have to go through the amp to set the gain. And it distorts with the gain all the way down on every track at volume 9.
