Bavsound stage 1 speakers resistance for base system

Hi all, I have bought the Bavsound stage 1 speakers for my base audio system. They have finally arrived and I checked the resistance which is coming in at 2ohms. The speakers in the car are 8ohms, so is it safe to drop this much ?

I have mailed Bavsound and they gave me a poor response (basically no confirmation that the 2ohm is correct/safe), so has anyone else fitted the Bavsound in their base audio and checked the speaker resistance before fitting them ?

I have the Alpine upgrade and those speakers were 4ohms which makes me more suspicious of the Bavsound 2ohm version.

Poor customer service from Bavsound.

In the base audio setup the woofers and front speakers are connected in parallel each 8 ohms so the effective impedance connected to the headunit is 4 ohms stock so you should be sure that 4 ohms are safe.
Either way the headunit outputs a 25W signal at 2 ohms so that's why I reckon Bavsound are sending you 2 ohm speakers.
You should have ordered the Bavsound speakers for the Hifi system since you technically have a Hifi amp system now.
Anyway, speaker ohm and power ratings are not a big deal at normal volume levels.

Thanks for the feedback. The base system speakers are 8ohms in the front and rear doors and 4 ohms in the subs. The front and subs are connected in parallel so the head unit was running 3ohms front and 8 ohms rear.

The Alpine kit splits the subs and front speakers, so it is running 4 ohms front speakers, 4 ohms subs and 8 ohms rear.

Is it really safe to drop from 8 ohms to 2 ohms on the rears ?
