If you are getting a weak output, chances are it’s because you need an external device for the amplification of the sound. Some vinyl players have an in-built amplifier in which case you can directly hook up the player to your speakers. But if the player has only Phono option and no Line option, then you will need to connect the player to an external amplifier which then gets connected to the speakers. This will solve the issue and give you the proper sound from the vinyl.
