I am attempting to make a Kundt's Tube experiment with a 250W (3 Ohm Max) Subwoofer that I had taken out of my old home theatre sub box. I have a frequency generator that produces 12-16VDC but its just not enough power to really get this sub pumping.
I was wondering if there was a way to either make my own, or bypass the need for an amplifier but I need to give this sub that extra boost. I dont have alot of money to spend but I do have alot of time lol.
Any help on this would be awesome! Thanks ahead of time.
P.S. - If you need additional data, let me know and Ill try to get it to you.

The power going to the subwoofer is coming out of the Frequency Generator which is 12 - 16 Volts or 3.6W - 4.8W
Thats my problem, I cant supply enough power through my FG alone, I need to somehow either set both the sub and the FG in a circuit that would power both the FG and the sub or find a way to bipass the need for an amplifier all together.
Sorry if thats not what you needed, just wasn't sure 🙁
Thank you though for repliying 🙂
I think I may have misinterpreted what you were talking about.
I thought you were referring to something with tubes...vacuum tubes.
I guess I should ask: What is "Kundt's Tube experiment"?
If you just need an amplifier for the Subwoofer then there are many solutions here on DIY.

Here is a video showing exactly what it does.

I have a similar setup going on, but its much bigger lol. I have an 8-inch subwoofer instead of that basic speaker on the left of the tube in the video. I just need to find a way to give the sub its own power supply, while also being able to use the frequency generator with it, like in the video.
Im pretty new here and had no idea there were amplifier solutions already in place LOL so any links to them that might seem appropriate to this would be awesome, thanks

It looks like a regular consumer grade audio amplifier or receiver was employed in the video. If you have an audio amplifier that can deliver the power you require, then you're all set.
Amplifying steady state tones will generate a whole lot more heat than amplifying a musical program will, so be vigilant. It might not be a good idea to use your nice receiver or amplifier. If you look at resale shops, you might find an old receiver that has at least one channel working. A boombox with an auxiliary input might work too.
