    I just got a new passive sub, but will not have a seperate amp for a few weeks. My question is can I use the speaker hookups on the powered sub to power the passive sub? Since I am using the LFE Pre out on my Amp, will the sub crossover interfere with the signal? The reason I ask is that I thought the Amp would be controlling frequency, not the Sub, so any signals sent from the speaker outs would be the same as the sub is getting from the Amp.

    No you can't. The speaker hookups on the sub aren't powered, they are input jacks. If you connect the passive sub to the powered sub you won't get any sound. Do you have an unused receiver laying around the house somewhere? If you do that can be used to power the passive sub.
