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!!!

Yeah, pay no attention to the speaker designer demonstrating exactly what I said. https://youtu.be/tMAO9LPsups?t=290

welcome to the forum @toiler...

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.

and brace yourself for certain participants who enjoy telling others what their life priorities should be and how best to spend your time.

Three easy payments,
Thank you for your welcome to the forum and a bit of humour. You are right, I was not really expecting some of the response I received but that’s okay…everyone is entitled; some more than others

You could always grab a pair of Aiwa EXO9 portable, battery operated speakers.  1 by itself is good but you could blue tooth 2 together and be rocking out some serious Beethoven!

Okay, technical answer here.  Like others have said, putting an 8 ohm speaker onto a car deck will work just fine.  I actuality, the car deck power supply does not have to work as hard.  That JVC deck will output 22 clean watts per channel into a 4 ohm speaker.  However, the deck will only be able to output 11 clean watts per channel into an 8 ohm speaker (half as much power output due to resistance, but less strain on the power supply).

That being said, the Polk Atrium are actually 3 db more efficient that those JVC marine speakers.  The JVC come in at 86 db sensitivity.  The Polk Altrium 4 come in at 89 db sensitivity.

It could very well be that you won't notice a volume difference here.
