I was given 4 car speakers. There is nothing marked on them. I would like to hook them up to my 8 ohm amplifier on my paging system. Is this possible?
Yes you can. Each car speaker is 4 ohms so you would have to hook all of them up in a series connection in order to avoid an ohm load that is below 8 so the amp doesn't fry. Hook them up like this for a 16 ohm load and you will be safe.
