No, you can't mix the signals easily.

Single terminal speaker = definitely not biamping.

To truly bi-amp your speakers internal crossover to tweeter and midbass
have to be on seperate circuits. That's why there are two sets of input
cups. The two signals never meet inside the speaker.

Supposedly from what I understand (and some genuis herein this newsgroup
will say I am sure that isn't much) the purpose in biamping is to reduce
the amount of back emf created by the larger midbass speaker getting to
the tweeter. So if it has to run all the way back to the amp and then
all the way back to the tweeter supposedly it's less and the difference
is audiable.

Yes, connecting the bass and treble outputs of your mini
hifi could blow it up, fry it, burn it out.

There's really no easy way to solve your problem.

There are two seperate 'high' and 'mid' filtered speaker level
connections on the back of your receiver? What type is it?

Do you mean 'bi-wired' or truly 'bi-amped'?

If the former, two wires coming from a single connection on the back of
your receiver, connecting it won't be a problem.

If the latter, there's no easy way to go about it. Unless you take the
drivers out of the cabinet and seperately terminate them on the back of
the enclosure and connect the corresponding speaker level outputs from
your receiver. Even then, because there are no hard specifications on
either end at this point, there's no telling how it all may sound.
Crossover points in the receiver or capabilities of drivers in said 'old
nice hifi speakers'.
