    My subwoofer is on order, but I thought it would be smart to do a little homework first: I keep reading posts where people are using Y-adapters to wire their receivers to their subwoofers. I have a L & R sub output on my receiver and L & R line inputs on my sub. I could run wire between the receiver and the sub and my guess is that this would work. If I ran two wires, wouldn't this simply give me 3 dB gain? If so, is this the smart way to wire the sub? Additionally, I don't need a Y-adapter with my setup, right?

    One more thing - I've read that Monster is now selling THX certified sub cables, a single 16' cable for $79.95. I've seen the same cables on eBay for under $20. Would this cable be a smart purchase?

    TIA, Bill

    If your receiver has L&R sub out then a L&R audio cable hookup will go directly to your sub and give you a 6dB gain over using only the L or R. You do nt need a Y cable in your setup as that is more for people like me whos receivers have a single sub out (in my case I have 2 sub outs for two subs). Then you need a single male RCA that splits to two RCA males at the other end. In this cae, you can also wire a single RCA cable from the sub out to either the sub's L or R but the sub will be 6dB quieter.

    Bill,

    It sounds like you are set. You can use a simple 2 channel RCA cable to connect both outputs on your receiver to both inputs on your sub. I cannot imagine any reason to have a THX certified subwoofer cable. Any good quality shielded cable will work fine.

    The Rat Shack cable should be more than enough. We're only talking subwoofer frequencies here. I think premium cables are overboard for sub duties. But to each his own.
