Here's one for you all, as I try to hack together an audio solution on a budget.

I am going to be using multiple 2 channel amps for my setup, but that leaves the center as odd man out.

In the longer term, maybe I'll just throw in a rear center, but I can't do that right now. In the medium term, the amps I am going to be using are designed to be bridgeable, so I can do that for the center.

In the right now term, however, I am trying to kludge something so I only have to purchase 2 new amps immediately. So here's the oddball question.

I have an old Technics SU-Z980 that I have been using. It is an okay amp, imo, if nothing amazing. Decent amount amount of power, nothing really horrible about it. What I would like to do is continue using it to drive the center channel for the time being.

I have the vague notion that driving one channel with no load on the other is a Bad Thing. Is this correct? Is there a cheap & easy way to put a dummy load on the other channel to eliminate this problem? If so, I can just do that.

If not, or perhaps anyway, can I bridge this thing by just connecting the center channel to Left + and Right -, then jumping the remaining two outputs?

It is currently running a pair of 4ohm speakers, so it seems happy enough with that load, but I don't know if that is all I have to worry about.

Thanks.

Put a four ohm ceramic resister on one channel. 10 watt should do it with no input to that channel.

Oh, heck, that is easy. I'll definitely just do that, then, rather than experimenting and taking the risk of toasting it.

Thanks a lot.

or you might be able to biamp the center channel if the speaker/crossover allows
