I plucked the following from a thread on another message board: "If you have a choice, wire your sub like I did. That is: preamp out from your A/R receiver or preamp, to the preamp ins on the sub amp. Then, preamp out from the sub amp back to the preamp ins on your A/R receiver or preamp. This will take care of all high pass filtering in the crossover, and will avoid cascading crossover conflict between the sub amp and the LFE channel on your A/V receiver or preamp. Set the subwoofer control in the base management set-up to sub woofer "off". All low frequency info, from the crossover set point down, will now go to the sub. When done this way, the sub will play a part in all your audio inputs, not just LFE channel input from DVD's. The bonus is your mains will now have more available power and less distortion in the upper bass and lower midrange. Bare in mind that the LFE channel may not have any info, thus your sub could languish while your mains struggle." Does anyone have any thoughts about whether this is a good/bad idea? Theory sounds good, about having the sub fill areas other than LFE, but I am new to this so will defer to you all. My apologies to the original poster.
