Jbl amp connect to Seicane Headunit

Hi All,
I have bought a head unit from Seicane, ( yes I know I’ve heard bad things since).
Anyway I have connected the harness and everything works except no sound.
Looking through other threads I believe it is because the JBL amplifier is not getting power.
There are two wires coming from harness marked amp con.
Wondering does anyone know where I connect these too.
Any help would be appreciated!
It’s in a 2008 tundra limited

 

I would go through the headunit setting, find where the amp turn on/off is and tick it. Most likely it in the off position by default.
Generally it's under setting, device, sounds, amp something.

Try that.

The amp con wire is for turning on aftermarket amp. You dont need to connect it to anything.

 

Got it going!
follow these instructions, the red writing at bottom of picture,
But then you need to cut the blue wire from 16. Radio antenna (you don’t need this) and connect it to a wire marked amp cont, there are two of these on harness , I used the blue and white.
And it fires up the amp and sound ,,

On another note, radio reception is pretty poor from factory antenna but I’m gonna try and live with that,,
Now I gotta try and get back up camera going

 

Having same issue. I hooked up power antenna to amp and now have sound but only front. And the aux l in to fl out ot rear doesn't do anything. Only the amp con wire jumped to pwer wire gives sound. Anyone fix this or am I screwed .

 

Is subwoofer working?
Could be your settings in the Seicane unit

 

Let me look...So you have bass and rear hatch speaker working in yours?

Did you get back up cam to work?

This thing looks really nice but sounds like shit.

 

Any updates here? I can't find anything to connect the Amp-Con wire from the head-unit to.

 

I too am looking for an update please! I've done lots of radio upgrades in my life, and i've always built my own harnesses. Up until this one because of fancy JBL system. Same boat, can't get sound with Seicane radio. 07 with JBL non navi.
