Best way to feed a rear sub?

I'd like to install a rear sub on my HT setup. Currently using two Citation 7.4 passive subs on the front powered by a Citation 5.1 preamp and a couple of Marantz monobricks. I want to setup a sub using the same (Citation 7.4) sub and monobrick about 30ft away from my preamp on the rear sub output of my preamp. Since this is a passive sub, and I'm powering it with a monobrick amp, what is the suggested way to feed my sub? Should I use decent RCA interconnects and place the monobrick with the sub, or should I have the monobrick with a short interconnect near my preamp and use 8 gauge speakercable to feed it?

I use the built in 80hz active crossover in the preamp to feed my subs, but don't know if you lose more low fequency response with line-level or amplified level cables when feeding 30ft of cable.

Thanks!

i respectfully disagree with gunbei. it's almost always better to use short cables and long interconnects, particularly if you can utilize xlr ic's between fully-balanced components.

BTW, what is a "monobrick"? half a monoblock? whatever, i like your word; can you imagine pink floyd singing about "just another block in the wall"? -kelly
