WRONG. NEVER set your gains to max, EVER. Gain is meant to be matched to your head unit's preout voltage. You can usually set the gains by putting your head unit's volume at about 3/4, and then turn up the gains until it mixes nicely with your midbass, or until you hear distortion, then turn them down a bit.

I really dont know where the gains are so I put them like a little bit above half way where the white mark is at.

the Xover is what u set to mix in with ur midbass.

U dont turn ur volume up 3/4 neccesarily, u turn it up as loud as u would listen to it. Then start turning up ur gain until u hear distortion or when u kno its too much, then u turn it back down a bit. Then u set ur Xover to how u like it. setting the Xover too high will cause ur subs to sound messy.

Ive noticed that if you set your gains too high your amp gets hot/hotter quicker and thats never a good thing.

What if the lowest your amp goes is one volt, and you have an older hu with 1 volt preouts. If your gains are at max, and there really is NO distortion in the subs, and the amp isn't soo hot you could fry an egg on it, then there is no problem.

Well, capone, you can also set your gains accordingly to mix in good with your midbass, so as the subs are not overpowering the rest of the system, and also providing adequate low end. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Technically to accurately set gains you should use an osscilloscope or a digital multi-meter. Each of those is much more accurate than the ear. If you have access to either i suggest you use that to set your gains.

If you are interested in these ways, holler at me, and i will explain them to you in depth.
