I installed a sub and 4 way speakers with amp on both on my 2012 cascadia but now when I use my cb radio my voice and a loud pitch noise comes from the speakers, any reason why it’s doing that?

Its not uncommon.  You amped the input from the radio so it has amped up any amount of noise that was already there.  You probably had the noise before that you could not here but not its loud enough to hear.  Some call it feedback.  To elimate the noise you would want to check that the CB healthy.  Check antenna for SWR.  This alone will cause feedback.  High SWR will show up as noise.  Get the SWR as low as possible.  You can sometimes change the noise by relocating the CB antenna away from the AM/FM antenna.  Elimating the noise is usually done by fixing the source of the noise.

A secound though is to turn down the gains on the amps you installed as well as make sure all the grounds for the amps are at the same place.

The old klesache you have noise because you have a loud CB.  If the mod has been upgraded this will cause extra noise.  You might turn down the mike gain some and cut down on the noise.

How is the subwoofer wired on a 2016 pete 587? Radio is only 4 channel
May 5th, 2018
Most of the manufactures in semi truck amp applications are using speaker level signal input to source the amps input.  The regular speaker output from any radio will work.  The only thing needed is to trigger the amp on.  On the newer models 2005 -up are using the BT ISI DIN harness and the blue wire with a white trace is used to turn the factory amp on.  So hook it to the similar color on your new radio install.  
Older models will sometimes use a seperate wire to do this.  Color is not as important as it will vary.  It is usually the only one left to hook after all the speakers are hooked and power hook up is finished you might notice one wire left and there is no sound but radio shows working.  If this occurs and you are sure the speakers are working and radio is wired correctly.  I have used a old common sense trick to actually test a trigger wire.  Use a inginition wire like the red one and add a pigtail to it with a 1 amp   Read more...
