Today I installed an amplifier and subwoofer with my stock head unit using a hi/low crossover box. Once I just about finished everything, the radio has no power now. The fuse is good. I also discovered that all the windows but one wont go down with the one touch button feature. They go down if you hold the button down continuously, but wont go down all the way just by hitting the button once. All have that problem but the front passenger side window. I have checked all fuses to be sure there wasnt any other problems and they are all good. Any feedback is appreciated.

 

Found the problem. There is a fuse behind the radio that had blown, everything works now.
