Can I use a subwoofer with an Accuphase E-202 amp?


Hey
I am wanting to get a subwoofer to fill out my Acoustic Energy Aegis One's (I will upgrade speakers once I renovate my listening room)
I use an Accuphase E202 amp which is turning 40!!!!!! this year which is quite amazing when I think about it.
Anyway does anyone on here use a subwoofer with an E202 and is it possible?
Where do I hook the sub into? the "Pre out" or do I need a high output speaker cable from one off the speaker outputs?
I live in fear of blowing my amp up if I get something completely wrong.
Any help would be greatly appreciated
Thanks

Why not just get a self powered subwoofer and run it from your pre-amp outputs?
Sorry i should have mentioned I am getting an active subwoofer.

So the pre out is where I should connect it? the reason I'm confused is because someone told me I needed to get a "high level speaker output cable" (or something like that) and connect it to the speaker outputs because it's an old amp.

I connected one to the pre out before and everytime I turned the subwoofer on & off my Accuphases build in trip switch shut the amp down for a split second.
The only active subwoofer that I know that can take an output off an amplifier is those made by REL. Are you looking at a REL?
