8 ohms in parallel with 4 ohms is 2.66 ohms.

To get a 3.75 ohm load with a 4 ohm woofer, you would need to parallel that with a 60 ohm woofer . . . Here's a helpful formula I found for figuring that out:

you would get 1.333 ohm if you wired it that way.

the formula is,

1/[(1/ohm)+(1/ohm)]

so you'd get 1/[(1/4)+(1/2)] = 1/0.75 = 1.333

the way you'd wanna wire that is connecting all 3 coils together.
1/[1/4+1/8] = 1/0.375 = 2.66
1/[1/4+1/60] = 1/0.266 = 3.75

I have a better one for just 2 resistors in parallel.

(R1*R2) / (R1+R2)

Only works for 2 resistors though (or sub impedance)
