Alpine ktp-445u powerpack

Those look right to me. That thread has pics and gives step by step on what to do to make the harness 100% plug and play. Great instructions. Should be pinned at the top imo

 

You are an absolute hero!

 

That should work with the power pack right?

 

Yes it’s exactly what I did

 

So the alpine doesn't have red wires. Which wires did you connect to it?

 

Remind me what colors the alpine has instead of the red wires

This video helped me out ALOT. It’s not our head unit but essentially the same.. this will help you out. Let us know how it goes

 

Hey so on the metra female part there's no orange/black wire? What do I do?

 

Orange and black should be the illumination wire, for dimming. The Amp wont need that.

 

He explains this in the video I posted above

 

I have full wiring schematics for the tacoma head unit linked in my signature

 

To clear up confusion, I just installed this amp and instead of red wires coming from the Alpine harness, it’s a yellow one. Also, in the Kicker Key harness, there are two pre-soldered red wires and two pre-soldered black wires. On the Alpine unit, it’s just one black (ground) and one yellow (battery). I spliced the ground wire into the Metra ground wires (3 wires connected) and I spliced the yellow wire from the Alpine harness to the two yellow wires on the Metra harness (3 wires).

I checked the fuse to the radio, and it’s 20A, which means you can hardwire right to the harness making this 100% plug and play. Watching the above video, he states his radio was not 15A, which is what’s needed for this amp. So he had to run a wire to the battery and ground to the chassis.

After setting this up and plugging it into my radio, it sounds awesome! Definitely not necessary to run this to the battery.
