What makes some amps sound cleaner than others? I have a Sony 4-channel car amp that is suppose to be 600 watts i put this in to power speakers in place of my Rockford Punch 160.4 thats 20 watts a channel i'm not trying to say this vs that but trying to figure out why the Rockford sounded more warmer and cleaner? I tuned that amp as best as i could and on my Kenwood EQ to get the sound of the Rockford. had to turn it up for it to sound good. The difference is day and night between the two amps. I like loud clean sounds if you were wondering but not abusive. Is it because the components used in the amplifers? And yes i checked all of my wires and rca cables and its not my install i don't think the amp is defective it just doesnt have that clear and warm sound to it idk why Rockford really did it when i had it in.
