Well thanks to you guys all my sons new equipment will arrive tomorrow. I have One question My son just got the Epik sub, When I connect this to his Pioneer VSX 1021K receiver there is one sub RCA type jack out on the receiver, and two RCA jacks in on the Epik sub that say low level input. Do I need an RCA Y adapter? If I recall this is how I did it years ago on my old system. What I am trying to figure out is, are all the LFE output as mono? cause there is only one RCA out on the amp, how do they combine both left and right signals on the amp with only one RCA out? so why would there be two RCA inputs on the sub? And would it be better to hook it up the other way using the high level input. I am a bit confused.
