One concern is 2 ohm speakers with a home amp. You need a very high quality amp that will be happy at 2 ohms. I'm not aware of any receivers, not that i'm an expert, that would handle speakers at 2 ohms without tripping the protection system. I don't understand why you would want to use car speakers in your home. There are numerous home speakers available for any budget. Those car audio speakers are in a cabinet aren't they? Otherwise you will have other problems to deal with.
