I have a fosgate 750r hooked up to a sundown sa 15 dvc wired to 1ohm. What do the dials on the amp need to be set at? On the 750r there's 4. punch eq, frequency hz, infrasonic filter, and gain. I know what gain is ( it's not a volume knob) but what do the other dials need to be set at. The box has 3ft of airspace tuned to 33 hz.

I have a sundown sa 15 dvc wired to 1ohm what do I need the dials set at on the amp. Punch eq? Frequency? Infrasonic filter? What do these do I've tried google but I can't find anything. It's a fosgate 750r

Yes it's a prefab , I found sonic enclosures makes a thunderbox specific to the sundown sa 15 but I'll have to wait a few weeks to get it. It costs more than the sub does. The prefab is just to get me by until I'm able to get the thunderbox. Side note: this stuff is addictive, I started with a cheap pioneer 12 inch sub ($35) and a 28 dollar box with a pawnshop 300 watt Jensen dinosaur of an amp. Moved to the sundown sa 15 and fosgate 750r wired down to 1ohm. Now I'm talking to singer for an alternator upgrade because I want 2 sundown sa 15's and 2 750r's and my little 90 amp alternator just couldn't take that, along with a battery up grade and big 3. When I first put the original sub in I just wanted a little bass. Now I'm planning on my 1st spl event and I just want to be ready. But for a month or 2 1 sa 15 is good for now. I've gotten to a point in my life where I can afford this to a point, but it seems like a always want bigger. This is all going in a 2015 hyndai veloster reflex edition w/chrome 18's

I'm not sure it didn't give me port dimensions,it's a slot port and all other info is this: Volume : 2.5 Cubic Ft per Chamber, Box Frequency : 32 Hz. Dimensions: 20.5" Wide x 18" High x 19.5" Deep. Hole Cut-out: 13.875", Mounting Depth: 10-1/2".

I have 1 sundown sa 15 750rms and I am pushing it with a fosgate 750r at 1 ohm stable. The specs for the sub calls for 3ft of airspace and a box tuned to 35 hz. My box has 2.5 ft of airspace and is tuned to 33 hz . Is that close enough? Do I need to get a custom made box?
