Can my amp power four 4 ohm speakers?

[mhutchins]

I have a Kenwood KA-3500 integrated amp rated at 40wpc minimum. I have 2 KEF C80 4 ohm speakers. I just bought 2 more KEF C25 speakers to round out the sound. I plan on hooking these up on channel B in the back of the amp. Is 4 4ohm speakers asking too much of my amp?

Thanks.

I've had a 3500 powering a pair of 4 Ohm KLH 20 model Twenty speakers for a couple of years now. Sounds great, no issues with heat or anything like that. Plenty pf power for those supposedly inefficient speakers. Now, whether it's doing any damage or not, I have no idea.

Nice little integrated. Cute, too.

Welcome to AK .....That is a nice little integrated amp you have. I had one and loved it. As to hooking up 4 4ohm speakers, I would not. You say you want to round out the sound, what do you mean by this? I guess the question is what are you trying to achieve

Very few amps and even fewer vintage amps can handle a 2 ohm load. Your Kenwood is not one of them. It should be fine driving one 4 ohm pair at a time.

This might seriously be solved with "Series". What comb filtering...

Can you explain further? Is there a simple wiring diagram?

 

[mhutchins]

For the record, this amp was cleaned internally and any bad parts replaced by the previous owner 2 years ago. It works flawlessly.

One 4 ohm pair at a time....

 

[mhutchins]

Can I wire them as show at the bottom of the attached file?

The diagram for two speakers in series is the one to follow. Two 4 Ohm speakers in series (for each channel) will produce an 8 Ohm load (for each channel).

 

[Blue Shadow]

Yes, the second diagram as Joe said.

 

[mhutchins]

So, I've been doing some reading online and there is something called series-parallel wiring. It maintains the same ohms as the speakers. Curious if anyone had tried this.

 

[JoeESP9]

I don't quite understand how series parallel applies here. You will be connecting two speakers to each channel. Connect them in series per your own diagram.

Obviously, using this configuration I would connect all 4 speakers to the same channel.

I am playing 3 sets of speakers in different areas of the house. I connect 3 amps each running a set of speakers, all playing same music.
Get another integrated amp. Amp1 TAPE/REC (out) to Amp2 AUX (in). You can chain amps. It is a great reason to decide you need another amp.

Your amp cannot be bridged like a pro amp can. Also connecting all the speakers to one channel would be mono. And a third thing is wattage. When you connect 2 speakers to one channel they share the wattage. With 40wpc each speaker would get 20 watts. If you connected 4 speakers to one channel they would each get 10 watts.

This would plug into A input Left.

This would plug into A input Right

Resistance in Series is additive. You would have all four speakers engaged at the same time and the amp would be happy at a ~8 ohm load.
