A wye-connector used to split a signal into two lines is being used properly; a wye-connector used to mix two signals into one is being abused and may even damage the equipment involved.
Hello GuysThis is my first post here, great forum btw!Anyway, in our gym we have this setup: We have two different areas and for each area, we have a seperate amplifier. For the entrance area, we have a smaller amp and for our "room of pain" we have a big ass amp for some loud music.The smaller amplifier is mostly sourced by an online radio and that's fine. The big amp is connected to a PC. However, sometimes we want the PC not only to provide the big amp, but also the small one to have the same music everywhere.We tried to put them in parallel with a special cable, but that almost killed one of the amps. It got really hot and the amp almost started catching fire.Is there a way to put the two amps in series so that we can switch the smaller amp from radio to PC? Like this?http://dl.dropbox.com/u/1706321/amp.png
Actually, we DO know, that it was kinda hot, also the amp started not working after a while. We had music on both amps though, w/ decent quality.

I would also like to use two SA-S3's one input via a Y (Wye) connector and combine their output in parallel into the Bose.
Exactly so. The amps are lovely, cheap and 12v the higher output are 32v so require transformers. Is this putting the amps in parallel and is it safe/advisable?

NEVER NEVER NEVER connect the outputs of two power amps in parallel. This will immediately destroy both of them!!!If you really need their combined power then if possible connect each to a separate speaker.The only safe way to combine the power of two amps is to invert the signal into one of them, tie the speaker commons together, and connect the speaker between their outputs. You must be careful, however. This will only work if the speaker impedance is at least twice the rated output impedance of the amps.It would be much simpler to just get an amp with the wattage rating that you need.Edit: I type too slowly (and I was interrupted).Edit2: On second thought, just get a better amp. My other suggestion is a technique that is commonly used in amplifiers, but the amplifier needs to be designed specifically to work that way.
It was going to be car audio anyway. Can anyone recommend any car audiophiles I can pester for 200w RMS amp suggestions?
Also, running an amp in. All amps? How long and what sort of volume permissible if so?
Thanks guys. The second SMSL shall be used for tunes on the back deck (or gin drinking station) and the lounge amp options will be small or large. It was going to be car audio anyway.

The claimed requirements are 20-200w so the small amp will fall short of ooomph if the Bose internal wizardry won't run sweet at 4 ohm.If anyone has thoughts, or even figures, I would love to hear them and counter suggestions for a similar setup would be appreciated.
Has anyone taken a look at those Bose speakers, anyway?
