Hey, alright so I can't seem to find any help on this issue anyway so I thought I'd ask here.

I have a aftermarket headunit (Kenwood ddx4) in my skyline r34. When I chose the radio mode on the headunit all I get is static.

I've heard it's because it's from Japan so the frequencys or something are different...Im honestly not sure why it's not working.

Is there a way to fix this so I can listen to radio channels ??

If the radio came from Japan *(installed in the car already) then the frequency band will be out.

If it is an Australian radio it shouldn't be an issue.

 

Assuming you have an Australian radio check that the antenna is connected to the head unit properly (it just pushes in). Air gaps in RF systems aren't normally helpful. Make sure the cable hasn't been damaged or cut anywhere.

 

An antenna cable that has been crushed is as good as useless as it will be creating an RF short, thereby meaning no signal will run the full length of the cable. Check the antenna cable for damage.

Thank you,
It is an Australian headunit and after some searching on other forums I found that window tint effects the antenna.
So I've bought an aftermarket antenna and will test fit it tomorrow to see if that fixes the problem.
I'm glad you found this info... never occurred to me. [emoji848]
I was going to suggest using an FM transmitter and see if the radio works when your transmitting from in the car.

Come back if your new antenna doesn't work. Happy to keep throwing ideas at you. [emoji16]

My 34 had the active rear speakers and I recall having to choose between powering the factory speaker amp or the radio reception amplifier with the blue trigger lead from the head unit. May be worth checking. Took me a while to find the right info too and I don't remember where I located it

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.

      I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things

      I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt

      So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm.

      Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
