Home speakers with car receiver possible?

I’m sure 4 ohm speakers will push the head set to it’s max. The 8 ohm speakers will be a bit quieter. No resistors needed. You have the installation instructions? It will give you the minimums and maximums ohms.

Need an A/B switch for inside or out.

I suppose you could use the fader option. Fade the outside to ZERO for the inside to work on it’s own, otherwise all 8 vs 4 inside.. OR the A/B switch option..

If you’re going to do a marine install remember the ground.. Keep it large enough and every joint use sealing butt connectors. Don’t cheap out.. 12 vdc can drive some very good home electricians nuts. Remember marine depends on the actual wire to carry the ground.. Don’t bond to a common lug or frame marine requires a ground for every circuit and that circuit directly to the 12 volt battery ground.  Marine requires that.. automotive does not.. the frame is common in automotive along with the firewall, to the ground lug.. it’s different..

Low voltage with potential high amperage and green connection don’t work well.. That can happen in one season of setting.. Use protection on the DC supply, keep battery terminals clean and treated with corrosion inhibiters and contact enhancers..

50 years of cleaning batteries. I’m pretty good at it.. :-) LEAD Contacts... NoCo is one of the best.. Red terminal pads and red contact spray.. Wipe off the excess, don’t drench it without wiping after. It’s good from -80 F to 200+ F

Enjoy

Arcticdeath, I will take the Modelo!!!

Imhififan thank you!

Oldhvymec, I will take awareness to the next level on my install, being sure to adequately ground and ensure all battery connections are soils and protected from corrosion. 
Thank to all; I’ve ordered the Atrium speakers from Am azon. Cheers

MC is totally mixed up. What a shocker!
 Auto electrics are made for 4 ohm. 8 IS like adding a resistor. It's usually an easier load for the amp. You might not even notice a difference.
I put my first 10" home speakers in my Scout Traveler. They sounded fine. One day while a.t work a thief broke out a window and pilfered them. Luckily he ignored the lb. of weed in between them. 

As you say fuzz tone, I thought from my reading of online forum information that the lower the ohm number then harder it would be on the receiver or amp.
