We're hoping to light some sort of fire under them to make em sound better!

The reason I asked is that local member, Jay bought an eBay 920 and you guessed it, it has a huge burn mark underneath the exact size and shape of a stove hot plate!
My personal opinion of the big Sanyos is that they sound really nice but they tend to be a little underpowered compared with BTL amped beasts like the M70, GF-9696 etc so they just don't crank that hard.
Beautifully styled and great build quality no doubt but conservatively amped - great battery life though.
My GF-9696 for example is a D cell destroyer!
