Motor speaker interface
Ok new to honda tech but will try to explain the best i can. Have aftermarket head unit and f22b2 motor. When playing any audio but for example i heart radio through phone and aux cable i hear acceleration and deceleration through speakers. Dont know how or why need to know something to go off of to start looking in the right place. Recently i did front suspension and timing belt component kit dont know if this info helps. Also would like to switch my auto to manual what all do i need. Thank you

Re: Motor speaker interface
Noise on audio systems in cars are caused by a few things, most of the time it is due to a "ground loop" noise can come from alt. [a whiny/siren sound that changes pitch as you increase and decrease RPM] this sound gets into the radio through the cars ant. in most cases and is because of an improperly grounded ant, it needs a ground at both ends.Another source of noise is ign. noise, a ticking\whirring sound that increases with RPM, [caused by spark plugs or speak plug leads.
The last one is induced switching noise, electrical "click" anytime a switch is actuated, [turned on/off] like stepping on the brakes, turning lights on/off.
Almost all the noises are caused directly by a grounding problem.
So question is what kind of noise do you have? 94
