Weak Radio Signal

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...?

Michael.

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!

      GOT SUM's RB34

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
