If you leave it on "full" until you get a
sub just be careful when you play a really bass heavy song...

Yea, I've assumed as much. I've got the crossover in my deck set at 80hz and
I've been watching the volume. I've also got the amp's gains down to near-null.
What I really want is an RCA to Symbilink converter so that I can really take
advantage of my Eclipse's 8 volt outputs.
