Right now I just have the BKII connected directly to the amp that's hooked up to the reciever's sub LFE sub-out(split with my subwoofer). Output is very low due to voltage differences between the receiver and amp and I've had to keep my receiver sub setting at +10 with the amp at full power. I plan on purchasing the Radio Shack SA-155 mini amp as a volume control booster for it. Is there anything else I should look at? Perhaps an Equalizer or crossover unit? Also, right now I'm considering changing around my setup. Here's a diagram of the current setup and my future plans: Which setup would you guys recommend? Any other suggestions? Perhaps a raised platform rather than a sheet of wood would work even better?
