Ohm (in loudspeakers) is impedance or load.

Less impedance (ohms) make the speaker easier to drive.

An amplifier will give more power (watts) if connected to a lower impedance (ohms) speaker.

However..beware that amplifiers usually have a lowest recommended impedance to be used with them, disregarding this might cause damage to the amplifier.

Therefore in a car I would suggest replacing like for like, i.e. staying a 4 ohms.
