thats the outcome of 2am conversations with a friend at an audio shop.
he accidentally said "we should glass em in the roof" i immediatly said "lets make it happen"
used 2 iron bars welded across the inside sheet metal. then screwed em to the bars. they are 03 models bought in 04. had a problem with the plastic feet breaking though. i had to rig up some metal to make em stay.
i was told they would overheat upside down. negative! runnin an old re xxx never got hot enough to shut off.
