So i bought a new amplified speaker the other day :
MFJ383 Mobile Amplified Communications 2-3/4" Speaker With Volume Control Canada
Reason for buying this speaker is because my previous amplified speaker was a set amplification and only had on/off capability. The amplified speaker is for a BCD396T, i wanted the ability to control the volume at the speaker instead of using the knob on the radio. Anyways, i installed it last night on my 2005 Grand Prix, but unfortunatly installed it with the engine not running (installation included plugging in the cigarette lighter into a 1-to-3 adapter and plugging the jack into the scanner, how difficult). As a background i also have a BC796D installed in the car and running an amplified speaker as well. Currently i am using the BCD396T off of batteries and using a typical Maxrad antenna, blah blah.
So back to my situation, as soon as i start up the car, the speaker lets out a high pitch whine that follows the RPMs of the car, higher rpm, higher pitch. This occurs even if i unplug the scanner, as long as the speaker is on, no matter the volume level, i can hear it. The speaker is located down by the floorboard underneath the front centre console. I never had any issues with either of the other amplified speakers, nor any noise picked up by either scanner.
Is there any ideas on how i can get rid of this problem? Is the speaker just garbage (as another side note, the other two amplified speakers are quite cheap compared to this one and doubt that they use better components)
Would moving the speaker help? Is there someway to ground it better? Would using the scanner with the AC Adapter help at all? Input appreciated, thanks.
