Hi, I'm from lithuania, so i don't speek english well. I have amplifier real 75w minimum 4ohm, and I have two speaker 1st- 50w (for long time) 2- 25w (for long time) booth 4ohm. How to wire that I can connect this speakers to amplifier?😕
Srr, but i don't understand my speakers first radiotechnika 25ac-109 (25w), next speaker-Кливер 50 АС-201 (50w), so I have to connect booth speakes +to + and then to amlifier +, and the same with -? Or one speaker+ to other speaker - and then + and -( in one speaker and in other sspeaker) to amplifier +and-?
Not enough information!
1) Is the amplifier 2 channel (stereo) or mono?
2) Are there only 2 speakers total, but they have different power ratings?
3) Can you post a photo of the connections to the amplifier?

1)Mono
2)Yes
3)I don't have picture, but that simple mono homemade aplifier. TDA7294 in datasheet type 100w, but in reality about 70-75w.

Good, thanks! Now clear what your problem is!
1) You cannot connect the two speakers in parallel as that would give ~ 2 ohm impedance. This may be too low for the amplifier, cause too much current to flow and damage it.
2) You can connect both speakers in series without danger or damage, but one speaker may sound louder than the other.
3) you can adjust the volume output of each speaker by connection a resistor in series with each speaker and then connecting both in parallel.

Quick sketch added.
If you do not need to make the volumes the same, just use 4ohms or 5ohms. The actual value is not critical, tolerance can be 10% or better.
If you play music loud, the resistors will get warm so they should be rated 10watts or bigger. Big white square resistors are often used for this.
Clear?
Any further questions?
(Edit) I forgot to say that if it is not important to have the same volume, just connect both speakers in series without resistors:
Amp+ to speaker1+, speaker1- to speaker2+, speaker2- to Amp-.

Thanks cliffforrest, I chose this metod Amp+ to speaker1+, speaker1- to speaker2+, speaker2- to Amp-.
