2017 Tacoma Speakers won’t play but headunit still works

I’m posting because I haven’t yet found an answer, but I’ve run into an issue with my radio. It’s the oem entune system in the SR trucks, no navigation or anything like that. I used a taco tunes plug and play amp harness and wired up a 4 channel amp for my door speakers, but I accidentally had the speaker input wired to the output on the harness and vice versa. Stupid mistake, but now I’m not getting any audio from my speakers. Even after removing the harness and just using the factory plugs which worked hours ago perfectly fine, I still get no sound. I can use the headunit still and it works fine yet no sounds come from my speakers. Any help would be appreciated

 

try disconnecting the battery for a few minutes to reset the radio for starters. some radio's have internal fuses on the output-- some will automatically reset, others won't and require a new head unit.

 

Ok thanks. How will I know if my radio has a fuse that will be automatically reset? Will I just know if the radio doesn’t work after the battery is unhooked and reconnected whether it’s fried or not? And is it possible to replace the internal fuses or not really?

 

if the battery trick works, something reset. if it doesn't it won't. most of the time, they're not easy to replace without advanced soldering skills.

 

Have you tested the speakers? Not with the HU, use a known working source e.g., home stereo.
