Home speakers with car receiver possible?


Hello everyone, I recently purchased a new to me but used tent trailer. I realize were coming to the end of the season but I wanted to get a bit of a Headstart for next year! We like to have a little bit of music when we’re camping. I have purchased a set of 4 ohm marine speakers (JVC CS-DR621MWL) that I will be installing into the side of the tent trailer facing outward to the ‘patio area’. I also purchased a JVC car receiver. I would like to have some music inside the trailer, for mornings, evenings and even rainy days. I have been thinking about perhaps installing a set of Polk Atrium 4 speakers. These however indicate 8ohm resistance. I think the JVC car receiver (KE-X840BTS) would prefer lower ohms? 
What can I do?

Looking for ‘sound’ advice. I’m already ‘guessing’ about adding some sort of resistor but unsure if that is the proper method or even how to do it. No ‘guessing’ please!!!

You can add a resistor, sure. All it will do is turn the volume down. Much easier to just turn the volume down I would think. 

The receiver will be fine with those speakers. Just hook em up and enjoy. There is nothing like the sweet sounds of nature washed out by car audio. Of that I am certain. Why else would people drive to the woods but to turn it into what they had back home?
I appreciate that you have your own opinion. I think a bit of quite classical music in the evening or being able to hear a news broadcast is relevant and valuable, for me anyway. Cheers
If you read the earlier message, ,and don’t get the sarcastic humor, maybe I need to buy you a Modelo?

  Yes, that will work fine. 
Smile more, silly.

8Ω speakers are OK to connect to the JVC car receiver, but it can't provide volume level as loud as 4Ω speakers, you can turn the volume control up to compensate.
