Radio issues

I purchased a used 18 4runner that i knew had a few issues, after market exhaust that i recently changed back sounds great by the way ,thanks all who helped with the great advice . so the last issue that i have is that they installed a giant amp, and woofer that i never got to see . long story short i had the system removed and the tweeters were i gues wired directly to the amp original wires are still there , they wired the front speakers to as best as i can tell the rear speakers they only work when the rears are on . from vids i saw on youtube the tweeters are in series with the front speakers and as long as there are no tweeters they wont work . i also tried the power outlet and it dose not work even though the switch up front is on . im thinking they may have used it for something else they needed to power like maybe the amp dose anyone know where the fuse is for this outlet and any advise would be appreciated . Ps sory i lied about making a long story short LOL

 

There are two fuse boxes. One under the hood and one in the drivers footwell. Check all the fuses. Pull them and make sure they aren't blown.
