Two subwoofers for two channel music listening

Hi all , 
How do you hook up two active subwoofers? I have two SVS 1000 series subwoofers with both high level (speaker) and line level (RCA) ins.

Method one - Lets say the subs have high/speaker level inputs. So do you hook up the left sub from the left amplifier out and similarly right speaker out from the amp to right sub high level in? This set up is just like the stereo pair of speakers.

Method two - The alternate is from a preamp hook up the RCA line in of one subwoofer then daisy chain i.e. RCA out from the first sub to the RCA in of the second subwoofer. Not using a Y splitter from the preamp. Trying to use both red and white RCA from preamp to red and white RCA in of the first sub.

Which method do you prefer? Any benefit or disadvantage of one over the other? Thanks for your comments and inputs.

Yes, I could, for 2 channel. But I then lose my subs when in HT mode via my Parasound ZPre3 pass-through. I can double check, but although that pre has a sub line-out, it does not transmit the sub signal while using pass-through. Which means I would have to use the AV receiver line-outs with a splitter.

The RCA adapter might work though.

Seriously, not sure it is worth the hassle, but could consider it.

You get cleaner tighter lows, using the line level.

Do those adapters both transfer the signal into the amp, while also feeding out to the sub? For  some reason, I thought they only went to the input path. Or, are you saying use the spitter at the pre via the bi-pass connections?

If so, $10 and an additional cable (have one long length I am not using) could be a consideration.

@georgehifi. 
You will get a cleaner signal (bass) from the line level, as an amps speaker output, is far dirtier. 

Then why is REL recommend using speaker out?

I am more inclined to believe REL.

Go with what you like

Did you see and comprehend the circuit link I posted that all subs do similar to.And any tech will tell you line level has less distortions noise ect than speaker level will have.
