Fins pointed down don't work. It doesn't matter if you've got 70ft of airspace below the amps. Heat rises.
This seems to be a common no-no that quite a few people seem to be doing lately.
At the very least you'll have higher distortion and reduced output levels. Worst case scenario is a fried amp (big risk for hot running amps or amps with poor/no heat protection circuitry).
I've made it my personal mission in life to cure the audio world of this horrible affliction.
It's either this or the (false) belief that a HU will put out 50x4.
I don't even want to get into impedence loads and stereo vs. mono and stable loads. :rolleyes:
