Here is a good article on speakers (4 and 8 ohm): http://www.rocketroberts.com/techart/spkr.htm Note that adding a resistor to a 4 ohm speaker will help to keep the radio's amplifier from being damaged, but you also reduce the audio signal strength. You can still get 8 ohm speakers. I bought 2 6x9's on E-bay a couple weeks ago. I only needed one. Maybe I can trade for something minor I need for my 65 Marlin. I have a short list. If anyone has some Marlin parts and would like a NEW Delco 8 ohm speaker maybe we can strike up a deal. BTW the AM/FM radio in the Marlin worked after hooking it up. Who knows how many years it has been since that radio actaully played some music. I am trying to keep it from being tuned to any Rap stations. That may kill the radio (Hah!).

The factory speaker is a hard to find size, like 4 x 9 or something. I have a 6 x 9 in my 1970 hornet, but the big magnet on modern speakers is too large to allow installing the cardboard glovebox insert; luckily the glovebox is quite fine without it. Once ain a while I find things like the steel tire pressure gauge stuck up to it. Unless 77 is a different radio that the earlier Hornet radios (I doubt it) it wants 8 ohms. The problem today is it's hard to find 8 ohm speakers! Because really good transistors are now cheap and easy, 4 ohm and even 2 ohm speakers are common, and 8 ohm hard to find. On my truly old and delicate 63 Rambler radio, I soldered 3.9 ohm resistor in series with a 4 ohm speaker. The old radio probably wouldn't tolerate the bigger load on the final transistor. (I could mail you the speaker bracket from the 73 Hornet if you want it. The speaker however is trash) _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
