Gain settings and speaker buzzing

Gain settings and speaker buzzing
Installed amp. 8 gauge wire all the way to batter. I looked at the sticky for gain adjustment. It looks like my Cerwin Vega B52 amp has a voltage of 44.7 according to the chart. I turned volume on HU to 3/4 and adjusted gain. Doesn’t go past 37 or 38 when the **** is at about 1 o’clock. So I turned know down just to where it started dropping the voltage. Which is about 12 oclock. Backed off a little more to 11. But now with MP3 player on pause I get that hiss sound. Like a record player waiting to be played. And with radio off I get buzzing in speakers. So I backed off till the buzzing was tolerable. So now gain is at 9 o’clock. Haven’t had a chance to ride it yet to see if that will suffice but seems loud enough. I’ve tried ground in different places. Neck, triple tree. Nothing changes. Any thoughts? Am I missing something? Maybe the stock head unit just sucks? I attached pics of current setup.

It doesn't matter if using 2 ohm or 4 ohm. On the output of that amp looking at the output plug as it plugs into the amp. top left is right side -, bottom left is right side+. Top right is left side + and bottom right is the left -. Follow the wires to the speakers and make sure positive and negative are correct. Also 20-23 volts what you should run and not 44. When looking at the chart the numbers are per channel not total watts. The b-52 is 250 per channel at 2 ohms and 200 per channel at 4 ohms according to the specs.

No disrespect to anyone here, especially the OP, but this is why I NEVER suggest setting gains with a DMM to an audio newb!!!!!
Set your gains the old school way. Turn gains all the way down, set treble and base to neutral, turn radio up to 3/4 volume and adjust gains until you hear distortion and back off a bit.
Also, run your ground to the battery. Not on the neck or triple tree.

so another question. whats the point of all that room left on the gain adjustment? would i benefit from upgrading speakers? Or is the issue the Factory head unit?
