Hi everyone,

As per the question on the topic, does anybody know if a manufacturer makes an amp with an optical input?

I have a JVC head unit I bought quite some time ago & have now installed to replace my dead Pioneer unit & found out after I purchased it that it has optical out.

It seems strange to have this feature on the head unit but no manufacturer that makes an amp to take it including JVC themselves!

Would make a lot of sense to get rid of all the bulky RCA leads & replace them with one smaller one that also happens to eliminate some sources of interferance & the possibility of ground loops.

Cheers

Jared

you could prob get one from overseas - look up car amp with optical input in google

Alpine, 5 channel amp, MRA F350 , 550 also

Kenwood had a few

Coustic did as well

Audison processor

most are to simplify a multimedia setup

pretty random and most arent made anymore

most people stuff the link when they install it , so why bother unless you drive a silent car that you can hear the difference in the noise floor and dynamic range ????

troy,

because its cool to have - everyone knows that..

that market died a LONG time ago. also unless the have a totally DEAD room you are not going to hear any difference. a car is FAR from that.

every thing in a car is a trade off. want more speed - lighten it and it becomes louder. deaden it and its quieter but you notice the speed difference.

Have been here already, and didn't find much. Nothing in Australia anyway.

Or possibly look in to a signal processor (audison/alpine), you'll still probably end up using analogue from that to your amp(s) but you get a lot more tunability.

Defeats the purpose of having the lead in the first place unfortunantly.

I did omit to mention that one of the reasons I was looking into this was due to excessive noise in my system & thought if I upgrade to an optical setup I could eliminate one source of electrical noise.

Having said that I have been doing a bit of research & with what testing I've done previously, I now suspect I may have a ground loop either to my antenna or my left rear speaker. After disconnecting the RCA leads to the Amp I still have noise on this speaker. Changing amps also does not cure the issue

Thanks for the info may I ask what you mean by 'the link'? I was figuring I could just plug the Toslink lead straight from my head unit to the amp so I'm guessing I'm missing something here...

This does somewhat surprise me considering most new home systems are going to digital one way or another, whether it be Toslink, Coaxial or HDMI & unsually all three on premium systems. Not to mention the parts in circuit for going full digital are no more expensive & sometimes work out cheaper.

For what info I've been given. Will have to look into things further.

if you need toslink to remove noise you have a bad install of equipment failing. did you ask the question here for the noise ? I live in adelaide south if you want to meet up sometime, so I can listen to it and advise ? or post up the recorded noise and a small list of affected items, models as well

I'm sure the noise can be resolved without toslink.

dont forget home systems can use digital signal paths much easier then a vibrating, noisy, harsh environment car can. ditch the toslink idea

more then likely its not going to fix the noise on a bad install

This was one reason yes, & I was considering upgrading my amp from the crappy Cadence unit that rushed into the purchase of when I bought the car due to a hunger for some good audio.

It was not a good install, I have almost completely re-routed and replaced all the cabling appart from the RCA leads (also candence brand) and the ignition feed to the head unit.

The source of the noise is from the alternator as there was no noise with it disconnected when the engine is running.

I did end up replacing the alternator as I did discover it was giving the occasional 3V spike (measured with a oscilloscope). Replacing it did improve the problem but didn't eliminate it.

Other than the noise though admittedly the sound has actually improved with the new head unit so if I could cure this I'll blow my dough on an Intercooler kit instead :blush:.

I do head down the southern suburbs a bit as I have family down there, so would appreciate a specialists opinion. I should also try pluging another speaker into the left rear connection just to see if that makes a difference as it doesn't matter what output is connected to the amp.

Sorry if this seems a bit strange the way I am recalling all this stuff out of the blue. My ride was off the road for quite a while & only now am I getting back to the issues I was originally trying to fix.

Thanks will keep it in mind if I decide to go down this path

shoot me a pm sometime if you want me to listen to it, and that clarion stuff is from 2006

if you go that route contact Chris Rodgers on here, he sells that brand

cheers

    • You don’t need to use full throttle all the time to break these blocks, 500kw at the wheels in more then enough to break them even with an occasional squirt. Hell I’ve seen them break under 400kw
    • A work around is to install the R35 card style AFM/MAF on the cold side of the intercooler piping and the BOV on the hot side piping. Works well, also you can combat the revs dropping by adding a bit more ignition timing on the idle ignition timing table to slow the rate of RPM drop.
    • Understood. If you dont have a ridiculous limit,  Tune, T's and P's are in check, and arent bashing it all the time and doing the due deligence for maintenance(inc oil analysis) then its pretty safe. 100% agree, let your right food control it to some extent.
    • So these external kits with the machined block for remote solenoid mount will only work on a NEO head and RB30 or RB26 bottom end   For an R33 head on a 26 bottom end the remote vct kit is to resolve RB26 manifold adaptor plates etc  IF you try to use the remote VCT on an RB30 or RB26 bottom end with an R33 head then  you can starve the cam journal??? I have one of these kits from bits I had years ago before plans changed  I don't understand how that tracks with this video   https://youtu.be/RuPiI22Mplk?feature=shared   This looks like I can run the v termite vct kit to feed the VCT on an R33 head on an RB26 bottom end?!?!?   Lol.... don't v have these problems on RB20s
    • Yeah i know that MAF is no no for this type of BoV. The engine has no BoV and "hose/pipes" ..it was all deleted (or probably it was not even on the engine when it was bought  ) It does that "sutututu" noise which i kinda do not want(atmospheric is better IMO...but standalone ECU)  What are the cons of running without blow off on stock RB25DET NEO. It running 5-7 PSI max (it has boost controller)   EDIT: and can Nistune be "tuned" to know there is no BoV to i dont know "know" and be better for a car? I read so many info about no BoV. One guy saying it is bad and hurting the turbo/engine/car and other that it does not...
