Best Subwoofer Connection

OK, so I'm waiting on delivery of a JL Audio e110 subwoofer. I have a 2 channel setup. The on-line manual recommends connecting the preamp outs to the subwoofer's line in (l/r), and then going from the sub's line outs to the power amp. OTOH, I could just go from the second set of preamp outs to the sub's line in and run the signal in parallel without using the sub's internal xover. Which connection is preferred and best for a music only setup? I've searched this issue here, but I haven't found an answer that makes sense to me. Thanks.

I'm fairly certain that you will use your 2nd pre amp outs to the E110 directly, then you will be able to set up the sub using the external controls to adjust the E110 FULLY (you are going to have xover control)! Sending another pair of signals from the sub out, makes no sense in your system. Great SUB choice too BTW :-)

Thanks, guys. I’m running a BAT VK-3i into a Musical Fidelity A300cr dual mono amp (225 wpc). Speakers are B&W N804s, and I’m looking for a bit more "oomph" in the bottom range. Does this make a difference in how to connect the sub?

Nice system! 

Don't forget to get your sub positioned first in the room before you tweak the crossover etc.

I would still run the preamp output through the sub as a first option. Then it's a matter of setting the crossover freq and sub volume. 

Then try the second pre out method.  

I am glad I am not your neighbor. 

Good luck.

OK, now I'm a bit confused. If I go from the preouts to the line in (and run the mains full), then I can use the external xover via the controls. If I go from the sub's line out to the amp in, does that mean I have no control over the xover, and it just is what it is internally? Sorry to ask somewhat noob questions, but I have had very little experience with subs.

I believe all equipment will worked best within their comfort zone, I recommend use the sub line-output high pass the signal to feed the power Amp, your Amp and speakers will thanks you for doing that.
