I decided I was going to set the gain correctly on my amp using that tutorial above.
Here are the specs
RF Punch 325.1, mono (400w RMS @2ohms)
2 kicker 07CVR02's (2ohms draw from amp)
Panasonic hu (1.9V from RCA each)
14.1V to the amp from battery
I did the math and came up with 28.2V. Fine, great, grand, lets move on. I then downloaded three test tones (35, 40 and 50) at 0db. I cranked my HU up as high as I listen (40/40) and left the HU bass at +2. I turned down the gain all the way on the amp, made sure the LP filter was on and removed the subs. When I played the 40hz tone and used my DMM I was getting a 42.0V feed at the lowest gain setting and when I turned up the gain I maxed out at 48.2. WTF . That is way to high and no where near where I need it? What did I do wrong? If I do the reverse math with those ranges I get around 1000w. That can't be right can it? I know RF amps are under rated but that is just to high. The only way I can get it down in to the 20's is to turn the HU down to 20/40. What gives?
Thanks
