Hi Everyone (again),
I have a question that Google doesn't seem to be able to reply despite my intensive searches, so since everyone here has been tremendously helpful in my other two threads, I will once again rely on your knowledge to help me figure some things out.
As always, my budget is tight, my Electronics knowledge is not very extensive but with 1h or so of researching a specific subject I'm capable of understanding enough to engage myself in a discussion and although I have good soldering skills for minor things, my understanding of circuits schematics is very limited, so reading one is kind of like reading Spanish (I'm Portuguese, so I can understand the majority of it but the probabilities of making a bad interpretation is very high).
Here it goes:
1.) I have an Audio Decoder that I scavenged from and old radio, it's working properly and the Audio Output is a 3 pin connector (R out, Common Ground and L out)
2.) I have 2 (two) Class D Stereo Amplifiers that are Bridgeable, they can support 2 x 8ohm (min 6ohm) speakers in Stereo and 1 x 4ohm Speaker in Mono (Bridged), it's also working properly and the Audio Input is the same as the Audio Decoder, a 3 pin Connector (L in, Common Ground and R in).
3.) I have 2 (two) 4 ohm speakers that I want to connect to the Amplifier(s), for testing purpose I've assembled one amplifier in Stereo with both 4ohm speakers, the amplifier runs smoothly with lower volumes but as expected starts to warm up when the sound is raised, so this is an option that I've discarded.
Objective: Create a Stereo system using both amplifiers, each amplifier Mono bridged to one 4ohm speaker, and the input sound coming from one single 3pin audio source.
Problem I'm facing: If I merely split the Audio Output in two, both speakers will be in Mono and therefore I will end up with a Mono Audio System, which is not what I want.
Questions: 1.) If I only feed the Left(or Right) Channel Output and the Common Ground to one of the amplifiers, will the amplifier still bridge to 4ohm Mono without losing power? My guess is no but it's worth asking (can't test it because the speakers are currently not at my disposal for another couple of weeks).
2.) If I Split the Left (or Right) Channel in two, and wire it to both R and L Audio Inputs on the Amplifier, plus the common ground to it's given place, will the amplifier be "tricked" and make the Mono Bridge with only Left (Right) Channel ?
So pretty much that's it, I have a problem that I really can't work a way around it, mostly because I'm ignorant on the subject and never before worked with 3pin stereo systems (this also poses a trouble when connecting a potentiometer but I want to go step by step).
I'm at work right now so I can't draw any "schematics" of both questions I placed above, hope my description is sufficient for the time being, will try to draw something soon and place it here for ease of reference.
Thank you very much to everyone.
