Removing subwoofers

I removed some subs that came with a Lexus that I bought and now the car doesn’t turn on.I unplugged the battery and started removing everything that has to do with the subs. After I finished I turned the car on and it died after like 10 seconds and wouldn’t turn back on.seems like the car still had power because the lights would work.Would anything be hooked up to the radio itself?Anyone know what happened? Did I just cook myself.

Any tips are helpfull. Thank you.
