Yes you can. But don't.
The reasoning follows.
To develop 30W in 3 ohms the amplifier would have to apply 9.5V across it, and the current through it would be 3.16A.
The 170W amplifier would have to apply 36.8V across an 8 ohm load for it to develop that power, and the current through it would be 4.6A.
It is therefore quite clear that if, and only if, you were able to control the volume setting of the 170W amplifier such that it didn't apply more than 9.5V to the 3 ohm 'speaker then no problems would ensue.
But you can't control the volume setting like that can you?
So don't take the risk.

Don't do it! They're not compatible at all. You run a serious risk of fatally damaging either the amp and/or the speakers.
Either get an amp that can drive 3-Ohm speakers, or get some 8-Ohm speakers.
A 3-Ohm capable amp can drive an 8-Ohm speaker system, but an 8-Ohm amp cannot drive a 3-Ohm speaker system.

Radio Tech was my original trade. You will blow the amp. Amps don't mind running into a higher impedance, but they hate lower impedance than they were designed for.

Nah, you'll blow the speakers.

I think it will be the speakers that will blow LOL

You shouldn't have any problems.
