My problem isnt engine noise (hum/buzz) but more a (tick) not all the time maybe once every 2-3 minutes like the noise you make with your tounge on edge of teeth.

Any ideas?

hmmm thats pretty weird... does it happen on CD's AND radio?

does it happen with the engine both on and off?

anymore details would be handy... though im sure one of those guys that works in a car audio shop will just come in, blitz me, and give you the fix in about 10 seconds :sick:

Is this with the engine running? Or can you hear it when the engine is off and the volume low?

If it is with engine running it may be a DC electrical spike which doesn't affect the engine or the cars computer but can affect audio and alarms. Check all main power connections from battery to amps are tight and battery to chassis and battery to alternator and ignition coil connections, also battery power is another main cause for bizzare audio problems the best car audio performers always look for where they are going to install all the batteries before they look at where the subs are going. A stiffening cap might absorb the ticking noise. If the noise is heard with engine off and low volume it could be the noise floor that your listening to which means your amps are turned up to full position which means they are too small, the higher the gains are on an amp the greater the reduction in optimum audio range.

First you should see which speakers you get the noise from by just removing rca's one at a time it will narrow the problem down, if it is all speakers then you know your amps are good, then try 2 30amp or higher ground loop isolators in line before each amp remembering there is no guarantee on resolving noise problems over the internet, unless I can hear it, so you need to experiment a little.

Leon thanks for your tips and yes it is only when the car is running and seems to be the same at any volume. I recently changed to a larger amplifier and now found the ticking is worse. The ticking does not change as the car revs though

Is this gunna help?

turn the gains on the amp down and see if that helps... I had a noise problem the other day, turned the gains all the way down, readjusted my levels on the head unit, now its clean... dunno why the gains were up so hi, i think one of my mates must have been fiddling... :)

If it does help, youve got a leak somewhere... could be the RCA's or a miriad of other things... but it could also fix the problem to a point where it doesnt play the noise anymore...

also, you didnt answer my question about CD's or radio... it sounds like the cd player... when the laser moves and performs and action, that will leak through the RCA's as a DC signal into the amp, into the sub... turn the gains down, get new RCAs if that doesnt work...

    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
    • Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers 
    • The axels in my R33 seem tired, and have a bit of play in them. I cannot find any new of course, not interested in buying used, but I am looking to see if anyone can identify some cross compatible axles. In the states I have seen suggested for S chassis the J30 axles, however for the skyline (as best I can tell) the lengths are about an inch off (2.5cm) on both sides. R33 my measure L 22" R 24.5" GPT L 22.5" 24.25" J30 L 23.5" 25.5"  so shaft length is probably an inch wider. Not sure if someone has another still remanufactured option besides the J30. I figured worst case I can buy a pair tear them down and swap the center shaft. My other option was reaching out to GSP to see if they cannot piece together a set, since the axle stubs are still manufactured, I wouldn't think it be that hard to find a shaft or make a shaft work. 
    • Potentially some interesting data for some of you here; Hank Iroz from Iroz Motorsport testing a new Xona Rotor 5964S on a Audi RS3 2.5L DAZA motor. https://facebook.com/share/p/14EU18MyDqZ/ Cliff Notes: Turbo has the new Xona XRE compressor aero with an X4C compressor cover, reportedly 0.64 rear housing. 900whp (670kw) @ 37psi, 170k shaft speed, motor is making 2bar (29psi) boost by roughly 3800rpm, 500lbft (670nm) torque by 3500rpm. They overlaid a stock RS3 on USA 91 fuel (red), and a "Stage 2" RS3 on E85 (yellow), and this 5964S (blue) - the 5964S isn't losing any ground to either. Apparently out-flowing their prior tests with a Xona 8264S (green), and this 5964S (white) also has a smaller A/R than that did.
