Setting up an amp so they dont clip

I read that you can use a MM to set up your amps perfectly. How would this be achieved step by step so they dont clip?

Set up

A DMM is a digital multimeter.  You first determine what voltage you want to send to the speaker load by using Ohm's Law formulas.  See here.  When you have determined the voltage output that corresponds to the power in watts you want the amp to send to the speaker load, then you adjust amp gain until you reach that number in AC volts.  A good sine wave test tone frequency is required.  Use the CD player to play the tone, with the deck at full clean output.

Also, use the search button on this page and look for other posts about setting gain.

I'm not sure what you are refering to? MM??
