Hello all just got my 2003 CVT. Love it :D however huge problem :cry: . I installed my Kenwood deck from my previous car and when trying to listen to AM stations I get a pulsing sound which makes listening almost impossible. If I am very close to the station everything is fine but as distance increases the noise becomes insane. I had the problem with the stock radio but to a much lesser degree. I assumed it was the stock radio boy was I wrong. My guess is it has something to do with the small antenna or perhaps I do not have the radio grounded well enough any thoughts? Thanks

Back in the day a lot of radios recieved interference form the engine generator, so a suppressor was fitted to the housing and one of the leads. Not sure how it was set up but I found this on the net.

"Car radio interference generally originates in the ignition or charging systems or other electrical accessories. Interference is either picked up by the aerial or the wiring.

Interference is fairly easy to identify. The most common source of interference, a rapid crackling or ticking that intensifies with engine speed is from the ignition system. Two types of suppressors depending on the type of set (AM or FM) connected in different ways are used to eliminate interference.

An alternator or dynamo produces a whining sound that increases in pitch as the engine speed increases. Never connect a capacitor to the alternator field terminal. To eliminate this interference a capacitor is fitted between the warning lamp and earth. Interference from electrical components such as horns, windscreen washer motors, fan heaters, indicators disappears when these components are switched off. A capacitor fitted between the feed terminal and earth eliminates all interference."



Maybe this will help in troubleshooting where your interference is coming from. :wink:

I thought perhaps I had engine feedback but the noise I am hearing seems independent of engine RPM. I was curious if anyone else experienced a problem with the stock radio AM reception. I was looking at another post and it speaks of an antenna amp. Is there an amp that gets connected to the antenna? If so that would probably be my problem. Thanks

Hi Formularon:

___I am one of those that live off AM … Actually WBBM AM 780 here in Chicago. I don’t have a buzz or feedback with the OEM head unit but have read on this sight about the inline signal booster of the Insight not being powered when you swap decks. You have to reconnect a particular wire to regain its functionality but I am writing from memory. I know there was a thread about it so try “AM” or “Signal boost” in the search function and it should lead you right to it. Link it here once you find it as I am going to do a head swap sometime this year as well ;)

___Good Luck

I found that also yesterday in one of the FAQ sections. Connected the power wire yesterday (Pin 1) works much better but I still feel the antenna seems less than spectacular. I lose stations that have never been a problem in other vehicles. Anyone have an idea of a stronger antenna?
