I'm not using a Raspberry Pi on a TV / Home Receiver with HDMI inputs etc therefore I've read I'll need an amp or something to boost the audio out coming from the 3.5mm jack on the rpi3b+ ? My raspberry pi will be going inside a cabinet & for the video I'm going HDMI to DVI cable for my LCD monitor(which only has DVI/VGA inputs which is fine since it's just for video and no speakers directly attached to the monitor). The output however for the audio on the raspberry Pi 3b+ I intend on using the 3.5mm (or USB) & forcing that as the audio output via the menu / options within the config etc. So what exactly do I need from the 3.5mm (or USB) to drive a single 15w soldered standard arcade speaker ?
I've seen this: $19.95

https://www.adafruit.com/product/352 That's $44.90 + mini 3.5mm to 3.5mm right around $50.00 additionally I'll need to solder components to the board... I'd rather buy something plug & play for that combined price.
& I realized not sure if this would work, I have a similar one for my vinyl / LP record player but what about a Pre-Amp:
https://tinyurl.com/y8nkhfccfor 22$ it also comes with the power adapter. I don't know if this will work but others stated you just need to Boost the audio, would that suffice or whats the best most cost effictive way to output audio from the rpi3b+ using 3.5mm to a standard single 15w arcade speaker ?
Others stated in previous threads to use a USB Sound Card, any specific ones compatible with the rpi3b+ ?
https://www.adafruit.com/product/1475Do they sell mini 3.5mm out to speaker wire ? Will it be compatible with this set up ? for 6$ this is the cheapest solution. Setting up this particular way where is the config file so I can output pi via usb ? If possible I'd rather not type anything into the terminal because I can't see anything as I changed the code to hide things, it would be much easier for me to access a particular config file via ssh / WinSCP. If someone can help with that I'd appreciate it.
