Please help tuning
Setting up my system and Id just like some feedback if Im doing it right:
RG GTS HU with RF flash
GZ YB neo up front
Diamond Audio 2 channel HXM amp
I set amp to full pass, HU 3 notches from full volume and all eq flat, 1000khz -5db test tone, Oscope to 28 volts bike running. Then I switched to HP and started around 130hz and started working my way down tuning it. Left it at around 120hz because I wanted to be safe. Went for a ride and felt like I could go lower with my eq. In the garage with the bike running I lowered the eq and started getting low frequency distortion around 100hz with volume down 3 clicks from full. I raised the eq a bit till there was no distortion on that track.
Am I doing this right? Should I leave the gain and eq wheres its at now or lower the gain so I can lower the eq?

Here is the manual for the hxm800.2. Heres where maybe I messed up. I found the median between 40 and 400 hz and thats 220. I assume that would be at the 12 oclock position. The median between 40 and 220 is 130hz, which I assume is at the about 9:30 position. The median between 40 and 130hz is 85, the 8:30 position. I was shooting it be closer to the 8:30 position but ended up closer to the 9:30 position.
are my calculations correct?

What if you play them at 4 notches down from full at 85hz? Does it sound fine? And if so, when you click that one extra notch up, does it distort? If so, I would try resetting gains @ 4 notches down from full and see if issue returns.

Yea seems accurate to me...but even at 85hz, with 28v, they should not be distorting.

Hmmm, didn't know GZ had come out with some neo magnet yellow baskets. I don't know if the power handling is similar to the originals or not, but I've always run 150 watts to mine and have the Rockford flash on my GTS head unit and have not experienced any distortion at all.

My opinion is you did everything right. And I would probably keep the HP at 120 if you're pushing 200 Watts. Don't forget those pots can't be that accurate at 8:30 or 9:30 or 10:30. If you hear Distortion that's what you go by. What might be 100hz at 9:00 on one amp could be 120hz at 9:00 on the same model but different app. Sometimes you just have to use your ears

The pots they use on the amps vary from piece to piece within X % of tolerance. So setting them the way you described, maybe at 50hz or 120hz in one position or another.
