Oddball question, hooking up REL Storm III Subwoof


I just purchased a REL Storm III today used at a local dealer. they did not have anything but the subwoofer, Ie no, Neutrix Speaker connections...

I am trying to hook it up now in some manner, while waiting on my order of the connecting cable.

Using the LOW level input, is it possible to run an RCA out of the back of a DVD Players "audio out" subwoofer RCA output? I just did so and no sound came out of the REL. My set up does not allow me to use a Pre-Amp out, since I use an Integrated amp

Having no way to test the REL at the dealer, I am just hoping the thing is operational.

thanks

Also, asisde from the REL after-market speaker cable sold here by a Member "Zihkmark" are there other sources for the High Level Neutrix speaker connector?

I have gone to all the REL sites, Sumiko sites and live right by their HQs, ..I
am just trying to get the sub working prior to Monday.

Millenium Bill, I will try the TAPE LOOP, i had tried this, but on the "
PLAY" RCA on the JC Verider amp I am using with the sub, not the
"RECORD" RCA output.
I've made my own Neutric cables, the connectors are available at Parts Express cheap, and hi-level input is definitely the way to go . . .

Unless you have an old preamp sitting around that can be connected in parallel with your integrated I think you're out of luck
