How to make a rca output for subwoofer on Reisong A10
Hello I'm French and new on the forum.
I saw videos on youtube of the modding Reisong A12 and it's great.
So I bought the Reisong A10 and my question is: IS it possible to add a output rca on this on amp please?
I would like to connect a preamplified home subwoofer on the Reisong A10.
the output volume of the rca must vary in the same time of the speaker volume.
This will make a 2.1 system.
I hope someone can help me to do this please ?
I thank you,
🙂

You will have to bear with me............... I haven't done this for 60 years. I do not know why you are choosing to go here, I run a Polk Audio 15" powered sub that I got on a deal from Amazon for about $150 and it evidently has a 150w plate amp in it?
Anyway, about 60 years ago I saw a sub output project in an electronic hobby magazine. I built it and it worked ok. You come off your amplifier outputs (+) with a couple of diodes. This isolates everything, you then run the combination output through about a 100k pot, and use a capacitor to trim out the frequencies you want.
Once you have your gain set you can forget it.
I just checked Amazon and I didn't see any deals, BUT I see them in thrift shops all the time. A powered sub is the way to go in my mind, but to each their own.
