Subwoofer cable question

SVS is a great sub.. A lot better design.. Go for it.. front ports or IB (no port).

Better choice for sure..

Or any other brand than the one you settling for. Read their two paragraph installation instructions. Essentially, place the sub in a corner which is usually the worst location for most rooms. Then reduce the volume until the sub doesn't draw attention to itself. (Said with great sarcasm) It's simple all right.

For perfectly acceptable and reasonably priced custom length interconnects go to Blue Jeans Cable or Monoprice cable. 

The right subwoofer system will last longer than all your other audio upgrades. Well, unless low frequency becomes interactive and too much fun.

REL is very clear on thier instuctions on hooking up the Sub.  Cable is included.  They also have excellent tutorial videos.  Just go to thier web site.  

High level sub inputs are there only because the majority of customers do not have the abilty to run low level inputs and do not want to afford an appropriate cross over. They are the poor man's way of running subwoofers. To do it correctly your preamp should be connected to a two way crossover which then runs to amps and subwoofers. 

@emiliop , you can get a "y" connector to "mono" your signal for the sub. 

OP what kind of integrated are you running? There might be another way. I'm no expert but what are you working with?

I run a ZPre 3 in a tape loop on a C20 or MX110z. It adds a Remote for me, a fixed frequency Sub out for a passive sub and line level RCA for sub or main speakers..
I use it for subs only. The C20 or MX110z runs the main speakers via a MC225,240,275.

I paid 300.00 for it I think.. The use of a second preamp use to be pretty common.

Remember though there is a LOT of gain. You better have pretty good routing skills too. LOL Noise can be an issue because of the gain. Mine is still VERY quiet behind routing primarily.

Over the last couple of years, WEAVES and ribbons and very little use of shielding has netted me some fairly low dollar (cost wise) but high quality results in cables.. Really HIGH quality.. To the point of spending more money on cables to increase the sound quality, seems a little crazy to me..

I like the Helix from Mr. Wonka too. 
You won't find a product that produces higher SQ. You may find something you like the sound of better, but it's not because the product is better. I found usually it just takes a little time to sink in. Just because it cost more doesn't make it better.. LOL
