Anyone have this issue with the KL503? My buddy just received his and I went to set it up for him. Instructions say 1 to 12 watts pep drive so I set up for 10 watts MAX peak and set the power knob on the amp on #4 so he didn't over power it for it's first run. Amp is peaking around 300+ pep. I went home to talk to him and the audio sux maggots. Esses are chopped, audio is crunchy, doesn't sound good at all. Wondering if we got a bad one or if it may be something else. He's running a 2980 with a D104. Without the amp the radio is clean clean clean.
