I assume the answer is yes but underpowered. thought I would ask

If a CD of Seasick Steve sounds OK through a car speaker, it should work well enough.
A guitar cabinet specific speaker has design considerations for desired shaping/distorting the sound, and can take being pushed past its design power rating a little farther without damage, but unless you are Slash you can probably live with not turning it up to 11.
The CBGitty offered amp board by artec is rated to put out 2.5W of power on an 8 ohm speaker, pulling 0.5 amps. I couldn't find the spec sheet, but nearly every one of these has one that states output power for both 4 ohm and 8 ohm speakers. Back of the envelope calculation say that if you put a 4 ohm speaker on it (or a pair of 8 ohm in parallel) you will draw 0.8 amps, which will probably be fine. Though if you have a pair of 4 ohm car speakers, wire them in series to get 8 ohms.
The speakers should be rated for more watts than the amp to avoid burning the wiring or tearing the cones.
just to experiment on how close they have to be, We tried a hotone nano 5w mini amp head with a 200w 4x8 guitar cabinet and it blew us away how much volume it gave and how good the sound was.

Most car speakers are 4ohm and most guitar amps are 8 ohm.
A 4ohm speaker will be damaged quickly hooked up to a 8ohm amp, but you can wire 2 4ohm speakers in series(+ of speaker 1 to amp +, - of speaker 1 to + of speaker 2, - of speaker 2 to amp -) to work with a 8ohm amp.
Car speakers will not last long though with a guitar amp because they aren't made for that kind of use.
Damage can also occur to the speaker coil from ohm mismatch. One of the parts will be damaged for sure.
But the real damage to speaker coils comes from using a instrument that has a high level output in a small dedicated range of sound that's used with a speaker that's designed for a lower intensity wide range of sound for stereo audio output.
You can use car stereo speakers, but it will damage them a little at a time and eventually rag them out and make them sound terrible. If you use a guitar speaker, that will not occur.
if the 4 ohm speaker is of sufficient wattage then it wont suffer any damage. what CAN happen is that a 4 ohm load on the output of an amp can overload the output transistors and burn them out. basically less resistance more current flows , exceeds transistor capacity. dead amp. the only time you will blow speakers is if you are trying to put 100w through a 10 w speaker. then it gonna die!
