Been using this thread to wire up the new head unit.
I just noticed that the schematic "appears" to indicate splicing into 4 of the speaker output wires. Am I reading the schematic correctly?

Wires 1m 1n 1k and 1L each appear to be saying "splice" into the other speaker wires.

Just want to be sure before I start cutting open wires.

Thanks
