No Sub-Mojo

I have an Accuphase E-202 integrated amp that I'd like to use with a subwoofer since it has preamp/main out outputs. I tried to connect to a sub a few months ago, but was not able to get a signal to activate the sub. Anyone out there who has an E-202 and is using it with a sub? This is confusing to me, because I also have a Pioneer Spec-1 preamp that I'm using the preamp outputs to drive a sub, and that works beautifully.
I was wrong in stating there is no switch for normal/separate operation on the amp. When I hooked the sub up, I left the switch in the 'normal' position.
what kind of sub do you have? Does it have remote control volume? If it does, you have more options.
Good question....I am using an M&K MX-125, which has very limited controls, but is a great sub for music. I have somewhere around 12-13 subs, but none feature remote control.
You can use a set of your tape-monitor "record" jacks to feed your subwoofer. However, these are usually fix volume output (also called "line level") so the subwoofer you attach them to must have some kind of volume control (Note: The Pre-out jacks are variable loudness). It doesn’t have to be remote control but line-level volume is "all the way up" that is, really loud, so you have to have a way to turn it down to sane levels. Why don’t you sell enough of your 12-13 subwoofers to buy one (or two) with remote control?
Dweller, I think you were correct in your earlier post about the switch to select normal/ activate the outputs, the switch has to be set to 'separate', but that's where the caveat from my tech kicks in; it will also disable the amplifier output. Selling used subs is slightly more profitable than selling a used Yugo (who remembers those?). I only have two subs sitting idle, an Outlaw LFM-2 and an Orb Super 8. Good little subs, but not worth much on the second-hand market. I may just forgo the sub hook-up entirely because the speakers will have a 10" woofer, giving sufficient bass. Thanks for all of the suggestions and comments.
