How many speakers can I add to my receiver/amp?

by LaneW / February 14, 2010 10:36 AM PST

I have a newer Harmon Kardon audio receiver/amp. 120 watts, 2 channel audio (I guess is the term - has "speakers 1" and "speakers 2") I have a speaker on each post of the four - and want to know if I can add another pair or two of speakers, piggy backed on to the existing ones without frying the amp.... can I get away with it safely? If not, whats my option to add two pair of speakers?

Get a reciever that can handle more speakers. There is 5.1, 7.1, 7.2, 9.2 & 12.2 recievers out there.

Thanks... I'm stuck with the amp that I have, I'm afraid. And not trying to add speakers in the same room, but in adjacent rooms/areas.... was hoping I could just double up the speakers, but I expect it will overload the amp?

You should be able to then. Doesn't it have multi zone (room) hookup?
It would be in the manule on how to do it, most good receivers have multi zones & HK is a good brand.

Unfortunately it does not have multi room capability. 120 watts/channel, A and B speaker outs... but no multi room. Will I overload it with extra speakers?

What is the model number

Sometimes A &/or B is how a company names multi zone. 'A' being zone 1, 'B' zone 2 & then A & B both zones running at the same time.

But I need the model number to help any more so I can look up the manuel.

Run 2 speakers in one room or 2 speakers in another room's%20Manual/HK3480%20OM.pdf

see page 5 & 8, look for "Speaker 1 Selector" & "Speaker 2 Selector" those are your zone 1 & zone 2 speakers. It does not say if you can run both at the same time.
So yes you can, you just have to hook up the other speakers to the "Speaker 2 Selector" wire termals & them push the "Speaker 2 Selector" button on the front of the stereo receiver (the remote may have a button for it too) & you should have sound in the other room.

Thanks again

for all your effort here... much appreciated!

I didn't explain well, though - I have 4 speakers already, two on Sp1 and two on Sp2. Four in one room (large room). so what I'm trying to do is add 2 speakers in two other locations - do so so, I'd have to double up speakers on all four posts and I"m concerned that will be too much load.

thanks again
