Connect two audio amplifier ? Answered

Hi,
I would like to make a very powerful 80w bluetooth speaker, but the only great audio amplifier that I found has only two output for speakers.
So I was wondering if it will be possible to buy two and connect the first audio amplifier to the second one ? 
Cheers,


PS : here is the audio amplifier and the speakers that I will use :

Depending on the amp you may be able to drive 4 speaker.

NOTE: More speakers does not mean a more powerful sound.

As DU says you could connect the inputs together, they will need to be in phase or the sound output will diminish.

How much power do you want? there are amps out there up to 100's of watts.

Bridge the inputs of the amplifiers.
So you basically get two mono amps with two audio outputs each.

Since the amplifier has two 50 watt outputs I take it you want to connect two speakers to each output.

It may still have enough power to blow the speakers.

I could not get the amp specks but if you connect two the speakers in parallel the power to the one output will be 40 watts 2 ohms.

If you connect two of the speakers in series the power to the one output will be 40 watts 8 ohms.

Just remember each amp output is 50 watts 10 watts more than the speakers can take.
