[QUOTE="Firewalker, post: 8865427, member: 676743"] On the right use the voltage calculator. Take the RMS power of the speakers x 4 ohms and it will give you the voltage. So say the for the sub amplifier 3,000 watts at 1 ohm would be 54.72 on the DMM for voltage. For the 4 channel say the total RMS is 200 watts between both speakers, take 200 then 4 ohms would be 28.28 on the DMM. As Channel 1 should control the voltage for left and right front with channel 2 controlling rear left and right speakers. Or if you are using the front with components only then you put the tweeters on the front channels and the mid-bass on the rear channels. Works perfectly and you set the voltage on 1 for the tweeters and 2 for the mid-bass. Did mine that way for awhile always works. FYI you set your head unit to 75% and make sure you are using a test tone as well to set the voltage on the amplifier. If the head unit has BT use a test tone generator on your phone and connect it that way. I set mine that way and it works or buy the test tone cd from SMD if you want. [/QUOTE]
