Moin dear community, for the time being: I have already found a lot on the topic, but nothing that has helped me in concrete terms or from what I have become smarter. I am new in the field of audio in cars. I would like to install a power amplifier in my 93 Audi80 B4. I know the basic connection of a subwoofer to power amplifier as well as the cabling. Only I have a question about compatibility in the combination of subwoofer + 2 front speakers to a 4 channel power amplifier. I have a DSX A310Dab from Sony which only has a pair of chinch connections to the power amplifier (Chinch + Remote to power amplifier is clear), picture in the attachment. Is it possible with my car radio to realize the combination Sub + 2 front speakers somehow ? Or do I need a different one before ? If yes, how would I have to distribute Sub + speakers to the 4 channels ? Have read about connecting the sub over bridge and distributing the speakers to the rest of the channels , however I was connected with my car radio not really smart. Thank you already
