hi,

installed a system (alpine head, kicker 4-channel amp, separates, and a woofer) in a semi, kenworth if it matters, about 6 months ago. customer recently stopped in and stated a popping in speakers problem (the separates). i noticed that if one shuffled about in the cab, and touched various surfaces a pop or click could be heard. removed the inputs to the amp and replaced with shorting plugs, same result. did a back search here and saw that a possible cure was adding a ground strap or chain from the body of the vehicle to ground. does anyone have comfirmation that this will help or of any other possible solutions. thanks in advance.

Not sure what Alpine HU
Is this with just the radio or tape / CD playing or both?
Is the motor running also?

well it has problem with head unit connected with rca's or with them replaced with shorting plugs at the amp, and no the motor need not be running
