Lighting Problems

First off, I've been here for a while and I finally got stumped on a little problem. Last week, I installed a new alpine unit in my 98 4dr Ex 4cyl. The install was clean. Later that night I had to go to the store and when I got in my car to turn on the headlights, all my interior dash lights will not light up. It consists of my drive indicators on my cluster and console, vanity mirrors, air conditioning controls, clock, odometer and so-on. This happened to someone a while back but I paid no attention to it. I checked every fuse that I could find (drivers side, passenger side and engine). Any help would be greatly appreciated.

well i had that same problem when i installed a system in my friends nissan frontier. all it was, was a blown fuse, he replaced it and it fixed the problem. go through and check all your fuses again.
