I have a surround sound amplifier - 5.1?

Question

I was wondering if there is a size limit on the speakers that I want to hook up to it.Example -I have already hooked up two 70 watt speakers (the usual ones). And want to hook up another two 70 watt speakers - is that going to push the amp too hard.

Answer 1

Each channel is going to have it's own wattage. As long as the ohms are correct for each speaker. Most amp have built in protection from shorts and over current. You should be fine.

Answer 2

The wattage rating of the speakers has very little to do with  what the amplifier sees in terms of work.

It takes just as much power to drive a 250watts 8ohm speaker as a 50watt 8 ohm speaker. The wattage rating is only to indicate to you how much power can be put into the speaker before it gets damaged.

Speakers do not TAKE power, they are GIVEN power.

The impedence ohms is what determines how hard the amp will work.

There is a bit more to it than that. But in keeping the answer short and to the point. You will be fine as long as you do not connect more than one speaker per jack.

Answer 3

almost all 5.1 receivers are at least 100watts per channel so you will have no problem at all with the speakers you want to hook up. also, it really isnt a problem to hook up speakers that have a higher wattage rating than your receiver can handle. its when you put speakers that have too low a wattage that causes damage to the speaker and receiver. now when your saying your going to hook up 2 more speakers, Im assuming you mean not in the same ports that the current 2 are already in. now that will overload the receiver by messing with the resistance and impedence and cause it to blow out sooner than later.

Answer 4

What you need to do is check your amplifier's power rating per channel in the manual. If it says 100watts per channel. Then you can easily connect any speaker under 100watts to any of the surround outputs and it should be fine. But read the manual very carefully especially the technical info in the first or last of the manual. Good amps have some extra leeway on the top end so might still give out a bit more power than rated. Some lesser ones do not really give out their rated power outputs.
