Why 2 RCA's for Sub Bass?


Recommended Posts

Posted

I noticed this back in the day. On the amp i tested with (Kenwood PS-400M) splitter from one jack was the same as just one jack. My theory is that when mono sub amps hit the market they just plugged in to the existing stereo environment so the internals expect 2 channels and pull them together into one. The Brazillian market has "evolved" on its own so to speak - same reason we have all those unique species in Madagascar.
