Not voltage but speaker ohms make the difference. That is an ignorant statement. They both make a difference in this instance. Thats why I gave him an example. If he needs a different ohm load then he can adjust the formula. If the ohms change then the voltage changes also. Done cool your jets.

The voltage is 38.5. thats close enough.

Your ears are more reliable. Plus the markings on the amplifier are usually off because they are just printed on all the same. So I would never trust just setting the amplifier to 4 volts (example) just because thats your headunit preout voltage. With a dmm. They both get you close. Internet Thats what I told him to do. But he needed to know the voltage to set it to. He didnt know how to figure out the correct setting. I am talking he can use a formula to figure the 38 volts using the head unit voltage and amp rating. You mean the way I told him? OP here is the way to set it as given on this website. I already stated this. Amplifier gain No different formula. I would like to know another formula

Than why did somebody say 95 amps.170 shouldnt be problem if wire size is o gauge to the amp.

From what I have been reading its better to know the head unit voltage its more reliable.

He needs to know the voltage output of his head unit. Not if he's using this method. Dont agree . And why not? If you play a 50/60hz tone on your headunit, turn the volume up to 3/4 volume, plug your dmm into the outputs of the amp, turn the amp to ac voltage, and set the gain to the given voltage. Why would you need to know the voltage output of the amplifier?

Yeah that was basically my point. It will be in the box by the end of this weekend because I am busy with school. Any ideas about the gain? Use a dmm to set it. What is the volatage im looking for though, from my OP I last used a 60hz CD and set the gain to around 30 something volts. Where can i calculate this voltage. do a search on the internet the have graphs already made up. 50 hz for a sub. plus what is the headunits output 4volts?

How many amps is your alternator ?

Any other relatives around to help?

I know Jacob has great customer service skar?

I have used both the sa12s and the vvx12s on a aq1200d and you couldnt tell the difference. Would have had to use a meter they are both good choices.

my volt meter wouldnt work so i used my buddies and hes not home. ill try check it again today. but i know at the battery, with truck on, subs blaring, i was getting 13.3 and that was the lowest it dropped. with just truck on at idel no subs, i was getting 14.0 But when you measure at the amp it will also take your wiring voltage drop.

Check the voltage at the amp with your system on.

I have a box desighned for two 12 dcons could two12 skars work in same box? dcons not decons

Keep up the great work

title edited thank you

I kind of figured that.

Does the amp have a subsonic filter adjustment?
