Kenwood KAC-7202 wont turn on (by 3 users)

Hi, I've had this Kenwood KAC 7202 amp close a year. I disconnected it and put it away for about 2 days because my trunk latch broke. All i did was disconnect the subwoofer, power, grnd, the remote wire...(blue one) and the spkr wire that hooks to the sub...and i also disconnected the power cable from the battery...then when i decided to put it back on..the little red light wouldnt come on. so now i dont know what to do...i've tested the wires to the best of my ability and it says 12v....i also aquired a new fuse and fuse housing...dont know if that is what's making it not turn on/function properly...please help im going insane without my sub and amp:( thanks for ur time
