I have a stereo source, a stereo amp (input and output), but only 1 speaker (building a boombox).

Amp (RCA input) below:

Amp (stereo output):

I want to combine L+R (input OR output) to a single channel. I tried connecting both -VEs and/or both +VEs together but it didn't sound great. In fact, people online are saying it could be damaging stuff, and that you'd need a resistor or two.

What's my best option? I plan to run 3.5mm AUX, radio/bluetooth audio through it. Thanks!

  • Hopefully you have already calculated that this device does never output 500W continuous power to speakers. More likely that 500W is a nice looking decorative printing or a part of the name. 12VDC input connector has text 5A which means theoretical max output with 14V input and 100% efficiency is 70W. 5A is plausible for connector this small. It's common that one can buy from a webshop a device with attractive price and attractive something which looks a technical spec, but is actually worth less than the ink used to print it.

  • @user287001 - look more closely… it actually says .5A, making it actually about 2W into 8Ω ;)) At that kind of power, you can just bridge the inputs & no-one will care.
