Tuning Sub (Amp and LOC)

I want to adjust the gains correctly on my new install.

To do the LOC, I'm having trouble determining the Maximum Input Voltage for my Amp (Kenwood X501-1)

Running 1 4ohm Sub

Would the maximum happen to be the same as the top end of the Input Sensitivity (5V?)

Thanks in advance

Look at the input volts for the amp. A good place to start is in the middle position on the loc

The specs for the Amp read 14.4 operating V and that's it.
That seems high for input voltage.

I want to do the LOC w a multimeter but need the Max Input to do so.

No need for loc with that amp. It has it built in. "Speaker level input with signal sensing turn on" means you don't need a loc or turn on wire.

So I could just convert the speaker wire to RCA and be done?
