I installed a "Crunch" pzi 550.5 amplifier in my pickup. all went well it's currently set up to power 4 in cab speakers as well as a 5th channel to power the sub-woofer, an audiobahn 8"..
all works well but I have an alternator whine at low volume when the truck is running. I added audiopipe ground loop isolators to no avail.
I'm hoping there is a simple answer to eliminating this annoying noise.
All input is welcome.
thanks in advance,
Sparky.
there are various ways you can solve this radio interference. You call that Radio Interference when you hear a whining sound like that.
You can connect a grounding wire from the amplifier chassis or body or the negative terminal of your AMP to the ground of your car.
You can buy a capacitor (0.5uF / 150 volts) from electronic parts store i.e Radio Shack and connect the capacitor between the output of your alternator and the negative side or body such as bolts of your alternator. An auto-electrician can do that for you if you don't like to experiment.
You can purchase a noise eliminator for around $10 to $30.00 a piece. Here is the website http://www.mobilevideo4less.com/noisefilters.html
Hope this helps solve your interference.
