93 Distributor problem?

Last week my truck refused to start had it towed and checked out, distributor coil was fried. Replaced the part, finally got it back today. Drove the truck home, then to work, left it sitting for a few hours and now it won't start again. Is it possible I fried the coil again? I think a 2000 watt stereo system without capacitors may be the culprit, opinions?
