Additional information...
Your Amp, which in enclosed in the back of the sub, uses a seperate board for the Sub.
This means whether you use the Satellites or not, the sub still runs on it's own system, independant from the speakers.
Check this site out, it's posted as a MOD for cooling off your amp under high volume, but the pictures of the Sub (internally) are excellent... This MOD WILL VOID YOUR WARRANTY!!! But the pictures are great!
Thanks JakeJeckel (Phoenix AZ)
You did a great job with that MOD....
