I was told that 1 sa12 at 1 ohm would be louder than 2 sa12s at 2 ohms

To set gains properly you need a way to detect clipping.  A DD-1 or o-scope are the usual ways to do that, though there are others.  Without being able to detect clipping you are just guessing.

 I guess I guess I don't realize how important the gayness I use my multimeter to set it and it set at 77.45 volts. And that was a 55 out of 100 period when I had it set it to Holmes I had it my gain up to about 65 and it ran fine so somebody needs to explain to me what I'm doing wrong if I'm doing something wrong cuz I would hate to a mess up my equipment

77 volts seems high for a 1500 w amp. How did you get that number? I'm getting 75 out of mine and it's a 5k.

I get 70V on my 5Ks but the current also plays into the equation too. 77V for a 1500 does seem high.

Having a way to detect clipping is important to keep from frying the voice coils, especially when running over the rated power. When you bang on it and you are turning it up and the sound changes that would be a good indication that you are clipping. I run mine at .5 and they are way overpowered. When I smell my voice coils getting stinky, I turn it down a little.

The way  I came to 277 volts is if you ever have read the instructions on how to set gain with multimeter I did it that exact way taking your own sometimes your Watts I can't remember exactly how it was but I figured my owns were too so I did both speakers so for that's my might be where I messed up maybe I should have just done 2 ohms instead of 4 and then I got six thousand and I did the square root of 6000.

Take a look at this topic: sundown-amp-clamp-tests Sundown themselves clamped their own amps so people could see what they can do.

The SAZ-1500D did 49.25 volts and that's a 2000 watt amplifier (it was later renamed as the SCV 2000D). Your sae 1500 should do less than that. Think about it. But it's your equipment, you do whatever you want.
