Wrong again.

Edit: actually both of you were correct. So you'd need the freq dial around 9:00 or a tad lower to be at 80. Personally I'd run it at 100 or a tad higher.

Nope, 12 o'clock would be 180, 400 - 40 = 360 / 2 = 180

<edit>

Now my brain hurts! I just tried drawing it out and sure as **** I get 12 o'clock being 220

7 o'clock = 40
930 o'clock = 130
12 o'clock = 220
230 o'clock = 310
5 o'clock = 400

40 + 180 = 220
220 + 180 = 400

LOL not at all. The other post was correct about half of the difference between the two was 180 but you're not starting from zero on the dial. It starts at 40, so halfway would be 220

OK...I don't claim to be the smartest but good to know that I'm not loosing my mind then.

And this was my point in my own post earlier (https://www.hdforums.com/forum/audio...-question.html) about tuning these Mmats...whether they are very sensitive to exact frequency setting. That Freq dial is so frigg'n small and not marked very well. I was at 100 and they're definitely loud...but also a bit harsh to my ears. It was recommended to dial it down to 80 and try that. Hence my question about where exactly 80 is on the dial. I'm at 80 now but it's been raining the last couple of days so I haven't been able to get it out on the road.

I'd be interested to hear how you make out with your results chopper_man

Got it, thanks. If I were to set my gains with a meter and the "setting gains sticky" does 80-90 hertz and 150 watts sound like a good stating point for these speakers?

The MMATS are 4ohm so the Stinger would be 125amp. 125a x 4ohm = 500 sq root would put it at 22.36volts. Love learning new stuff!

I used 150 watts as a target because the Mmatts are rated at 100 watts. I read the RMS watts x 1.5 should be your target. Going by the chart in the gains sticky, 24.5 volts should be used. https://www.hdforums.com/forum/audio...e-speaker.html. This is where I read about multiplying by 1.5. I'm not saying I'm correct, it's just the way I thought it is to be done. If I'm wrong, please someone let me know!

All new to me but absolutely everything I read and watched on amplifier setup says the gains are based on amplifier output, not the "brand" of speaker or even what they are rated at for wattage (seems odd to me). Stinger is rated for 125w @ 4ohm or 150w @ 2ohm. It seems most use a 1k tone when setting the gain. Love to find a DD-1 meter and set it that way because then you can see where the exact point the HU starts distorting. Might splurge! LOL!

This is my favorite video so far:

I was using the search term "amplifier gain setup using dmm"
