Here it goes... i have a small dilema... when i connect the RCA wires i have to turn up the bass a lot on my headunit (pioneer ph- 6400) when i use the high level inputs i have the bass all the way down and it sounds awesome... so i got a new amp recently (rockford fosgate p 3001) it only has RCA inputs... i if i had a line input converter would it sound as good as line output or not?
