Default Any ways to test a sub amp without any subs to use?

Is there any way to test a subwoofer amplifier's functionality without having any spare subs to test it with?

Turn the gain all the way down and use a speaker. Then turn the gain up slowly.

Well couldn't you hook up a dmm to it and get some voltage readings? You probably won't be able to tell if it is sending a crapped out signal though, but neither would you with a speaker...

I could but like you mentioned I want to make sure it is outputting good signal. I don't have any spare sub/speakers right now and the amp I'm testing is a 2000 watter. I want to at least get the amp going to like a quarter volume (so a few hundred watts) to make sure everything is good. I plan on selling it.


Pretty pathetic that I don't have any subs sitting around. Usually I have at least one or two.

Go to a local shop and ask them to test it.

Last I checked, dummy loads for 2kw were like $400. You seriously don't have a sub anywhere? Can't you pull one from your car or computer/HT setup?

Fixed. Pawn shop guys know less about car audio than 5 year olds.
