Hi

I have 4 pioneer300 watt car speakers that I want to use on a regular 
(240 volt) surround amplifier instead of a car radio.

But on that amplifier it says on a bright red sticker: speakers NOT LESS 
THAN 8ohm.

Is there a trick to make a 4 ohm speaker 8 ohm?
By putting something in between like a coil or something like that?

I've heard about it but never had to look into it.

In a box, these speakers have a great sound, which is why I want to use 
them

Simple put two 4Ω speaker in series.

or to use 2:1 transformer

But that redudes the power by 50% and has an effect on the sound 
quality.

Anyway: this is better than having no sound at all.

Not if the 8 ohms only amplifier has 600W per channel, than the voltage 
is sufficiently high to drive 2 speakers in series.

But considering 300W Pioneer, these are for sure speakers that can only 
handle 30Wrms maximum. So even a poor audio amplifier will have enough 
driving capabilty.

Yes, it's surely worth a try.

Checking Pioneer Speakers advertised with 300W randomly:
Might even be 40 Watts.

belastbar ...

He has a surround amp, so he probably wants to use 4 channels for his 4 
speakers. If stereo is enough, then yes, that's what I'd try as well.
