well, basicly I have an ED 16kv2 and a nine 2 amp that had been working just fine in my pathfinder for about a year. I had a shop put it into my new car (98 lexus es300) yesterday by means of a Line out converter. About an hour after I left the shop, my sub blew. I was not playing it any louder than I had before and the gain was actualy lower than it was in my pathfinder. did the shop do anything wrong to cause this and do they have any liability for it?
