question about setting gain with dmm for sa12 v3


Recommended Posts

Hi there guys. I just bought an NVX JAD1200.1 and a Sundown SA12d2 v3. The dyno tests online say the amp does 1384rms at 1 ohm @14v so I am guessing closer to 1200 on my electrical @ 12v. This is my first time setting up an amps gain with a DMM. I set the gain to 34.6v and it does not seem to be hitting as hard as when I just did it by ear. Am I doing the formula wrong? Do I multiply the 1200 by 1ohm (load on amp) then do the square root or do I multiply 1200 by 2 (vc ohms) then do the sqaure root?

I would appreciate any help.

The sub is in a custom built aero port enclosure built specifically for this sub. When I just turned the amp up to what sounded good it was banging like crazy and shaking the hell out of my 05 dakota. Set with the DMM it is loud at my designated max volume but not great at all.

Am I missing something?

Thanks

just guess your gains. Using a DMM (to set gains) is completely worthless. You will have the same exact outcome.
