New here. Hey guys what is the best test tone to tune my Q Class L7 15inch 1200rms. My hu goes up to 40vol, I had it tuned at 28vol with a 40hz test tone and I got pretty decent low bass rumble but it wasn't loud enough for me so I decided to tune at 30vol with a 50hz test tone and it got a little louder but it stopped hitting the lower bass like I wanted it to. I'm thinking of using a 35hz test tone with vol at 30. So it's as loud as I want and it's hitting that lower bass like I want. What should my sub settings be on my hu when I do this? As of now on everything is is flat on the hu except for the sub settings wich are at 80hz and hu sub level gain up half way (12 and it goes up to 24)... I'm using an Orion 1500.1dz wired to 2 ohms, they state that wattage is 975rms at 2ohms but has dyno tested at 1205rms which is why I chose the amp in the first place.. I'm using a multimeter. My Oscilloscope arrives later today. Can I use a 35hz to get the sound I'm looking for? Below is the amp I'm using and a pic of my hu sub settings.
