"Y" Connector: Can Split A Signal How Many Times?


.
Your preamp has pre-outs for amps for two speakers, you use two "Y" connectors to create the ability to connect amps for four speakers.

How many times can you split the signal before it starts to degrade?

Depends on the output capability of the preamp and the input impedance/sensitivity of the power amps. No general numeric answer.

Every time you split the signal; you split the voltage. How much voltage each amp gets depends on the impedances the signals, "sees." Every added connection/interconnect will result in a degradation of the signal. You can keep splitting the signal, until there isn't enough left to drive an amp.
Sorry, Rodman99999. The voltage is not reduced with each split unless the preamp has inadequate current output. The voltage across every one of a fair number of paralleled power amps will be the same if (1) their input impedances are equal and several orders of magnitude larger than the output impedance of the preamp and (2) the preamp has more than enough current to feed those paralleled loads. Current/power will be shared but voltage should not.
