    Checked gain with an O-scope, sub is still smelling

    This one is frustrating. To start off, my setup is a pioneer 1200w amp with two comp c 12" subs in a ported box. my gain is set at 9.10v and my lpf at 80hz. I bought an o-scope because tuning gain by ear is next to impossible. Did everything you should, disconnected my subs, played a 40hz tone...

    How do I tune both my Amp and my Line Out Converter?

    I am confused on how you tune an amp and line out converter at the same time. I have an LP7-2 LOC, and R1100M Amp and they both have gain knobs on it. I understand that for each, if tuning by ear, you need to put your radio at 3/4ths volume, play a 40hz test tone, and then turn the gain knobs up...
