Phoenix Gold 800.1 - No sound from Subs

[05AztecRed 10+ year member]

I bought a PG 800.1, mono amp, 600W RMS @ 2-Ohm... I have 3-Phoenix Gold 10" - 250W RMS 4-Ohm DVC subs... I'm using this setup:

I've installed the amp in my trucks and everything is ok. None of the warning LEDs come on, except at inital start up, turns on/off with HU so the remote is good, RCA inputs are in the correct order, and all speaker wires have a good connection.

I can't get any sound to come from the Subs though... Here is what my spec sheet has on it:

I've been told to connect the speaker wires per the spec sheet in the top right corner, but that doesn't work.

Forgot to add: Do I need to adjust the Db gain knobs to ge a sound and than fine tune it, or does the stock settings work?

Any help would be appreciated.

Thanks!

Youre saying that the subs dont turn on at all? Tried putting other subwoofers on the amp and vice versa? Do you have "subwoofer" turned on in the HU?

dude you got to set your gains right there probly at 8volts and your HU puts out like 2

you probably have the sub shut off on your deck.
