I have been thinking about this a long, long time and finally decided to post something about it. I noticed when I first put the system in I could smell something different. Its not a bad or burning smell at all just something strange. It doesn't really matter what the volume is at or what my gains are at (little less than half on my 3500D) but the smell always comes about five minutes into playing. I would have to say it smells exactly like a bran new built computer (or computer parts freshly taken out of the anti static bag). Is this something to be worried about? I have not really tired pushing it that hard lately because I am not sure of some things. I know my subsonic is set to 28hz and my box is tuned to 30hz so that should not be a problem. I have touched the amps and all the wiring in the trunk and nothing is hot, some are warm but nothing too bad. The speaker itself gets warm from bangin it to some songs but nothing that I would consider "hot". Also, the amps are not even getting warm so I don't know.
I think it may just be the amps warming up?
