I replaced my head unit and only my front speakers worked. The rear speakers have an amp inside the the enclosure with them. How can I just bypass this and just hook up the speakers. My new head unit has way more power and I am putting in new speakers. Seems like you would just have to know which wires to cut and attach. Any help would be appreciated.

 

run new wires ?

 

I was trying to avoid that. Lol

 

Well I finally figured it out in back. If anyone else runs into this problem unplug the harness going into each speaker enclosure. On the left side of the truck you should have Black and Yellow and on the right side white and red. These are the speaker wires. You can cut them from the harness and attach them to your speakers. This will bypass the stock amp. This is for 4Runners with the upgraded 6 speaker system.

 

lol. That reminds me of when I did mine. I spent hours with a multi meter trying to figure out which wire went where. I figured it out, though... but on the downside, the neighbor's kids might have picked up a few new swear words, and that I am not too proud of. lol
