At first let you know these speakers are connected in parallel manner. Positive of amplifier to both of speakers and negative of amplifier to both of speakers. So put parallel resistance formula to get equivalent resistance.

We, everyone, know calculation.
But the trick is we should find, is the circuit parallel or series.
It is pretty easy because the terminal from the VOLTAGE source is connected to the same terminals of both RADIO.

It is simple calculation both speakers are connected parallel to source then total resultant resistance is 4ohms by ohms law I=V/R so, I=12/4=3amps.

Total effective resistance first find of both speakers.
8 * 8/8 + 8 = 64/16 = 4.
V = 12,
V = IR,
I = V/R = 12/4 = 3A.
8 * 8/8 + 8 = 64/16 = 4.
V = 12,
V = IR,
I = V/R = 12/4 = 3A.

i1=v/r
i=12/8
i=1.5 Amp for speaker 1
similarly i2=1.5 Amp for another speaker 2
hence total current i=i1 + i2=3 Amp
i=12/8
i=1.5 Amp for speaker 1
similarly i2=1.5 Amp for another speaker 2
hence total current i=i1 + i2=3 Amp

Actually current flow in the speakers is different due to parallel circuit. So. Do as above has explained.

The Answer of Harsha is also correct, bcos the total current will be addition of both & same current.

The two speakers are connected in parallel.
So, Rp= 4Ω.
According to Ohm's law:
I = v/r,
12/4=3 A.
So, Rp= 4Ω.
According to Ohm's law:
I = v/r,
12/4=3 A.

I=V/R.
For first speaker I=12/8=1.5A.
For second speaker I=12/8=1.5A.
Hence total current=1.5+1.5=3A.
For first speaker I=12/8=1.5A.
For second speaker I=12/8=1.5A.
Hence total current=1.5+1.5=3A.

The speakers are in the parallel form the main current gets divided 8||8 = 4 ohms and 12/4 = 3A.
