Help! Wired new head unit speakers amp and sub, won't play!
So I wired in a new head unit amp speakers and a sub all alpine. It is on a 5 channel mrx-v70 amp, all speakers are connected properly to the amp and the amp to the head unit via 3 RCA cables. Now the head unit has power and responds also with the amp but none of the speakers or the sub are playing anything. I have gone over all the wires multiple times also the grounds. I have no clue as to why these wont play so any help would be greatly appreciated.

How can I tell if the amp is in protect mode? Doesn't seem to be a special light or switch.
I'm going to grind the metal around the grounds maybe give it a better connection there is minor rust but I've hooked up too worse before so I can't see it being the problem.. We shall see.

Havent dealth with alpine amps, maybe the manual should have something on protect, if it has that feature.
Check voltage with a multimeter on power and speaker terminal and also rca voltage (make sure you are getting signal out of the rca's).
If you have a test speaker, connect it on the hu hi-output wires to make sure the hu playes music.
Whats the model of the hu?
