[QUOTE="Patthehat033, post: 7522010, member: 637337"] Okay, So today we had to take my brothers subwoofers out of his car to get my hockey bag in. Well anyways while they were out I got the idea to wire up his subs to my computer. We have a bunch of power supplies downstairs so I just grabbed one of those. Anyways I hooked up all the proper wires and the amp only turns on for about 5 seconds with the protective light and then turns off. This is with a 400 watt majestic amp. When I used a 100 watt amp, that we have laying around from awhile ago, the amp turned right on, but unfortunately doesn't have a low pass crossover so that amp didn't do much. I don't have the positive and negative backwards, so I am confused. Do I actually need a full 400 watt Power supply to just get the amp to turn on? [/QUOTE]
