if all the wires were cut before, check all fuses for blown fuses. this is most likely whats wrong. also, off the radio and off the cars wires there should be 2 power wires. off the radio the red wire goes to the 12v switched which should goto the yellow/red strip wire. then the yellow wire out of the radio should goto 12v constant wire which should be the white/blue wire. the ground wire should goto the black wire of the car. these are generic honda wire colors, you need to test with a voltmeter to check these wires and if these colors are incorrect its because there is changes in the harnesses wire colors between cars/years. i would check all wiring then after you have verified the wires are correctly hooked up, check the fuses THEN try to use the radio by turning the car on.
