how strong should a receivers/amplifiers output strength be for two 120 watt, 4 ohm speakers?
output strength for 120 watt speakers?

4 ohm speakers are going to be a little hard to drive, because the actual impedance is almost certainly going to drop significantly below 4 ohms at various points in the response curve. Get an amp that's rated for at least 100 wats/channel @ 4 ohms, with high current output. probably better off with 200 watts/channel amp for dynamics.
Overpowering, to much power, rarely damages speakers. You won't be in the same room with them at 100 watts. What kills them is underpowering and the clipping and other distortion that causes. The drivers can't handle that. Overheating and other nasty things happen.
So, IMHO, go for high power/high current.
BTW, what type and brand are the speakers?

Thats them. c61 xl
I will use the set for private listening.
Is it good or bad that they are 4 ohm instead of higher in terms of sound quality?
High current? thats new to me, what do you mean?

Very impressive looking. Unfortunately, I doubt if I can come by to hear them.
4 ohm, 8 ohm or even 16 ohm does not really have a bearing on "Sound Quality" as such. The impedance of the system is primarily the result of choices made by the designer/manufacturer.
The lower the impedance, the closer the system comes to appearing to be a short across the output section of the amp. Therefore, lower impedance systems are possibly harder to drive than higher impedance systems.
What this means is, you need an amp with a large power supply to be able to take the loads that low impedance will put on it. That will be a high current system.
Those speakers look like they deserve all the amp you can give them. And remember, underpowering is far more deadly to the speakers than overpower. Plus, reserve power equals cleaner dynamics.
Best of luck with your system.

amplifiers like that are to expensive. i don't have that money for a amplifier. well i'll let time pass and look for bargains or used ones... :/
thanks for your help, you are very kind.
