Default Fosgate t400x2ad Trouble

I am trying to install a t400x2ad I got and I can't get any sound. Power light is lit up. I'm only swapping out amps and my system worked just fine. Playing from an aux chord to Y rca's. Everything is connected correctly but I can't get the green clip light to come on when setting it up. Any tips on what and how I should test? i'm not too well versed in testing amps.

Map out your entire setup so that we can understand how you have everything wired.

Just realized, in reviewing the manual the sytem calls for a 60 amp fuse, I'm running it on 20 amp inline. Would this cause an issue with no output?

You should swap out the fuse, but if the current one isn’t blown, it shouldn’t matter.
There isn’t a green clip light, it’s blue/red.
make sure volume on your phone is up all the way and make sure all your connections are tight. Make sure your remote wire is hooked to a good 12v source that is on ignition such as your cig lighter.
I’ve noticed that the connectors (inputs and output side) on those amps are finicky, ensure they are seated all the way into the amp.

if all else fails, put your old amp back in and if that works, you have a bad amp on your hands.
