Motorola Speakers

[kg6nlw]

Alright guys, This is a mix-bag of electronics but has to do with Mother /\/\ speakers...I got this started and now I need a good solution...

I have two speakers a HSN4018A and HSN4005A. Both of which worked fine with the radio's they were attached too, but I had bigger plans for these two...

I stripped the connector off each speaker and wired up some speaker wire to it and put two Solderless Phono Plugs from Radio Shack on each end. I then plugged that into a RCA-1/8" stereo converter. I then plugged the speaker into my scanner, boombox, computer, CD Player and iPhone 3G.

The only way I hear *ANY* audio from either speaker is if I press it to my ear and listen closely..Yes before anyone asks the volume on each item was adjusted from OFF to full blast with the same results from the speaker(s) themselves...

Any ideas/suggestions/critiques as to why this speaker setup isn't working as planned would be greatly appreciated!

Regards,

Perhaps those are amplified speakers that require power (usualy 12vdc) to make them work. No other wires coming out of the speaker?

All of the devices you plugged the speaker into scanner, computer et. al. are designed to provide low-level earphone audio level, not to drive a speaker or high level audio. That is why computer speakers contain a built-in amplifier to boost the audio level.

It sounds like you put them in parallel with each other and if these are the typical moto 3.2 ohm
speakers you most likely have overloaded the audio output circuit of this "stereo converter" device.

I think I might be a little confused with your description.

NOTE: These are not amplified speakers

Thanks guys! Guess I'll have to go out and build/buy a power amp! It's an 8-ohm speaker.

fineshot1,

Thanks for the link. I had read that before and it's not quite, from what I'm reading, what I want to do. I want to have a speaker put in the front of the "family van" so that when out railfanning/etc I can listen to the car radio without blowing out the van speakers from pumping up the volume. That is the *end* result I'm trying to accomplish here.
