wiring problems
 

ok so i just bought two 12 inch kickers and a jl audio class d amp and had it installed by the guy i bought it from. it sounds great and everything, but something went wrong because my door ajar light is constantly on, my power locks dont work anymore from the inside of the car (they work with the key remote thing only) and also my stereo plays for about 30 seconds AFTER the key is taken out of the ignition. i have checked everything and cannot figure out where we went wrong. help would be greatly appreciated
