Can you help? Power Acoustik SPL2-520

[JustStartingOut 10+ year member]

I need to find the specs on my old amp, or more specifically, the line input voltage. I'm looking to run an Audio Control Three.1 line driver to the Power Acoustik. I looked around online and called Power Acoustik who first said that it didn't sound like one of their amps (wtf //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif) and then said that they don't have any info on it anymore because they don't keep info on amps once they're discontinued. I think the guy was just a douche, but I still can't find the input voltage on this thing anywhere.

I looked around quite a bit. I didn't find anything either.

All the current amps are 4-6v. The older ones are probably lower if anything.

It shouldn't matter much. One way or another you can make it work. You may have to turn the three.1 all the way down and never exceed a certain volume on the HU to avoid clipping, but I doubt that will be the case.

If you want to add a three.1 I seriously doubt the amps sensitivity will stop it from working well.
