I am hooking up the KDC-HD552U Kenwood headunit and everything is wired correctly.

Here is a picture of the manual and i show what i have connect with a check, and what i havn't *(should need to) with a X



When i start the headunit it goes into protect mode immediately after i turn the key.
The manual stats;


Troubleshooting-
"PROTECT" appears and no operations can be done. = Check to be sure the terminals of the speaker leads are covered with insulating tape properly, then reset the unit. If "PROTECT" does not disappear, consult your nearest service center.

Niether the 4ch or my subs amp are turning on, so i would assume it might be a problem with the remote wire?
Or would they not turn on even if i turn the key as long as the head unit isn't working?

Someone pLZZ help

I have the remote wire for the amps going to P.CONT on the graph.

If your HU isn't turning on then your amps shouldn't turn on. pull out your HU, unhook it all and rewire it. quickest solution

I just dont see why i would need to rewire it though when its sitting out, and i can see all the wires and connection ( i havnt put the headunit into the deck of the truck yet) so i see all the connections are fine.

You're 100% you wired it right? unhook all the speakers and everything and just hook up the three main wires and see if it turns on.

If it doesn't turn on hook it directly to the battery under the hook, just use the remote and tie it to the 12v source. if it does fix it the problem isn't the power

So i snipped some of the speaker wires and kept resetting and retrying one by one, and it turns out as i snipped the rear right, it worked then i realized.
I dont have my rear right wire hooked to anything, i just my rear left for both the rears i think and its split because i couldn't get to the wire or something i can't remember.

But it works now, everything turned on.
Ill rewire everything besides that rear right and call it a night.

Why are you using speaker outputs on the HU if your door speakers are amplified anyways?
