[Help] Where to connect my subwoofer ?

I have a Cerwin-Wega HT-S12 powered subwoofer that is hooked up to my DVD player which has a subwoofer out. Now I plan to get a new DVD player, where will I hook up the sub if the new DVD player doen't have a sub output? I also have a integrated amp, NAD C352, but it doesn't have an output for a sub. Can I get signal from Tape Out maybe?
Any help is appreciated.
Thank you.

Personally, I would get a Dolby Digital/DTS amp to replace your stereo amp so you can get discrete surround.

But to answer your question, you can use the speaker level inputs on your sub as a work around.

But the question I must ask is...why in the heck would you connect a sub directly to a DVD player??? You'd have no control over the volume.

Thank you for your answer.
I don't really need to control the sub volume. I only use it for movies, to enhance the low end sound effects.

So I would have to connect the sub to the amp and then the speakers to the sub ?

correct

You can always parallell connect your subwoofer to the power amplifier outputs. Then adjust the high pass cutoff frequency on the woofer to match the roll off of your satelites. I think you'll be quite pleased with the results.
