Weak Radio Signal

[R-sanichi]

Hi,

I recently replaced my stereo head unit. The radio signal comes on strong and weak in waves, and the volume needs to higher than CD and Aux as well. Is it just a poor quality tuner?

Any advice/suggestions would be nice,

Michael.

did you connect the antenna amplifier? that will be 90% of it.

Well I just plugged in what seemed to be the right cable. What I mean is, the only connection that I could see was the antenna which led to an adaptor of some kind ( a 2 pin female that splits into 2 male plugs - one the same as the antenna jack on the head unit and the other is smaller and I left it alone. Have I gone wrong here, Chris?

I might need to have a look and examine exactly what other wires are back there...?

ok so you have the antenna adpater. good. there is a single pin white plug that will be attached to that same lead. chase it back to the wiring you have done. that wire is the antenna amplifier. power that wire up with a blue or blu/wht wire off the radio and it will work.

Thanks Chris!

I have sorted it out now and the signal is as it should be.

I remember that extra wire but took the writing on the tag of the wire literally. Since leaving Japan, my excellent understanding of japlish has started to fade. I read the label アンテナアプ (antena apu) and thought it was to hoist an antena, but I knew the car didnt have one so thats why I ignored it. アンテナアプ really means to give more a powerful signal for the antenna.

Thanks again.

Hi all,

I seem to have a similar problem. well not exactly the radio sounds alright when the car is idle, but when i drive around the signal starts to get scattered and the radio just becomes really bad, but i notice sometimes at particular revs or speed the signal is alright, any suggestions. I have the AP745, could it be this unit playing up?

Just to clarify, does the single pin white plug "antenna amplifier" wire go into the stock wiring harness? When using a nissan adapter harness will it have a relevent wire to connect to? What I think it is is the power antenna wire?

Ignore this, yes is the answer!
