The drivers for the speakers should have some kind of markings on them that would give you a model number for the driver if you can find that you could possibly look it up on the Internet and find the impedance, even if you do not get the same driver you want to match the impedance…I briefly looked up "vintage RCA speakers and some have impedance as low as 2.1 ohms and 2.5 ohms…so 3 ohms sounds reasonable…The advise that you got from the car tech sounds reasonable..I would still take the 6.5 driver out and take a look at the back to see if you can find a model number or ohm marking, sometimes the ohms are marked on the back of the driver, if not you should test it for resistance rating while it is out…if its 10 ohms and you would get a 9 ohm speaker it would probably still work, but if it was 6 ohms probably not, the speakers do not have to match exactly but the closer you can get the better off you are…You may be able to find an exact replacement but a speaker of similar size, frequency response; sensitivity and impedance should work…the closer the match to the original design the more satisfying you experience will be…looking for replacement drivers try parts express, madisound Oak Tree Enterprises I would also do a search for Vintage RCA speakers and see what you come up with…another idea would be to get your current speakers reconed, you could probably do this your self with some knowledge and ability or you could have them re-conned by an expert from Parts express or madisound…if the coils are still in good condition this would probably be the beswt way…
