my friend has a 1999 honda civic 4dr and he wired a quick amp up and one day the power wire must of got pinched in the door (i know he wired it up wrong but he just did it quick) and now the headlights,taillights and dash lights wont work we checked all the fuses and we recently put a new motor in but this happened before the swap

 

no1 has any ideas as to what it could be?

 

noone can help me with this huh?

 

Did you check the fuses under the hood as well?

I would say it's time to break out the multimeter and find out where the power stops.

 

i would remove the amp reconnect all the wires and c if the problem still exists. where ever ur friend hooked up the amp for power might be robbing the accesories of power.
hope this helps best of luck
