hello gurus, I am planning to install ipad+istreamer as my music source in my car. Istreamer can bypass applez DAC and has a gr8 DAC of its own... but it has only 1 pair of rca output !!! One white one red. now I want to know how can this be wired with the two dd amps i have planned to install, one 4 channel, one monoblock. Is it possible at all for a stereo output as it dosent hav seperate front,back,sub...

My setup
Jbl components in front
Jbl coaxial in rear
Rainbow profi 12" sub
Digital designs cm1000 mono
Digital designs c4s 4channel amp

Now i dont want to spend a fortune on bit one. I want to know what are my options. Any device that can split the signals from the istreamer into front, back, sub ?or what else ?

[navin]

Why not add a HU with an Aux in and then plug the output of the streamer to the Aux in and let the HU provide front, rear, and sub outputs and controls.

[charles.chip]

Well, this seems like an excellent idea Navin sir,
But in that case the signal processing will be from the HU's DAC right ? The isteamer has an excellent 16 bit DAC of its own, won't it go in vain?

And i have a really old HU Pioneer deh-p5750mp, and although it does have aux in, it requires pioneer RB-10 cable
Now i have two concerns.

1. Sound quality, and the excellent iStreamer DAC going in vain
2. I need to control the music playback etc from the iPad and not the HU. Is that possible ? That's the whole point, i want the iPad as my audio interface.
3. Does aux reduce the signal quality or voltage as compared to rca ?

m sorry if i asked something silly, i am a complete noob and this is my 1st Audio instal attempt !

Cheers !

[charles.chip]

Can anyone please help me clear my doubts, i have to make my buying decisions soon based on this.

Thanks

Cheers !

Audio nirvana Gurus first of all I'm a total novice on icing a car. So need some help and advice. I have planed to purchase Ford Fiesta Classic TDCi LXi. This model doesn't comes with any speakers or any HU.
I have a super strict budget of 12 grands to spend on speakers and HU. No sub woofer because of space required for airport transfers and long journeys.
I'm looking for HU that's has USB, rest all is superficial as long as quality is there.
I have searched and thinking of going with Sony CDX-GT505U for the HU(Cheap with all CD, AUX, USB) and for the speakers going with Sony XS-GTF16272 16 cms in front and rear.
As I want to put the speakers in the door, in Fiesta we can only put 16 cms only that too circular and not oval.
Gurus please let me know if there is any other brand or any thing better for the super tight budget. Some plus minus will do.
Does Fiesta comes with pre-wiring for the speakers and HU in the car? Any Fiesta Classic owner who has iced his car let me know about the same.

The Aux in will let you use the DAC of the iStreamer. A USB in would use the HU's DAC. Aux is analog. USB is not.

Think JVC, Pio or Kenwod for the HU and JBL GT5 or Bull AUdio Coax for the speakers.

Thanks Navin Sir for your valuable inputs.
Can you recommend me a JVC,Pio or Kenwood HU that would fit the bill. Whats the cost of JBL GT5 and Bull Audio Coax speakers? Whats the difference of audio quality between Sony and the ones you have recommended sir. Hope I'm not troubling you by asking several questions.

I don't think any of the cars come with pre wiring. Please don't use Sony H.U. The quality of other H.U like pioneer and Kenwood is much better compared to Sony. Here is what I think is the best economical option for 12K.

Head unit : Kenwood with USB - Rs 6000/-
Front Speakers (Coaxial) : Auditor RIP 165C - Rs 2000/-
Rear Speakers (Coaxial) : Auditor RIP 690C - Rs 3500/-

Hope this helps.

Cheers!

Thanks for the information. For the HU I'm now thinking of Kenwood U6046 1DiN. How much would this HU be costing? Regarding the speakers, first time hearing this brand. I stay at Vashi, would ask the shops would they be stocking this brand of speakers.
Regarding wiring, the wiring should be as good as the speakers. Is there any brand of wire to be used for wiring. Zombie can you suggest me shop where I could get the HU and speakers you have suggested with a person who is good enough for it because I dont think I would be able to find the stuff you have suggested in Vashi, Navi Mumbai.
Now I have too started learning more and more about icing.

Eh? I though Fiesta has OE locations for 5"x7" ovals on the doors. One needs an adapter for mounting 6.5" (160mm) speakers there.

Almost all cars do. Otherwise, they will have to call for different harnesses at manufacturing time for models that have the integrated ICE and no ICE. At assembly time, components are not individually hand-wired - a pre-wired harness takes care of the wiring. The extra wiring for ICE costs much much less than the headache of maintaining inventory of different harnesses in stores at the assembly plant!!!

ok, but navin ji, if the HU wont use its own DAC how would it split the signals into FRONT and BACK? i can understand sub out can be based on frequency. But front/back/left/right ? how will the HU split that without using its own DAC ? as the input is from only 1 rca(red &white)


also now my plans have changed a little, i am changing my HU to pioneer P80RS II ! so it as a great 24 burr brown DAC of its own !!! Now will the sound be better if its 1st processed by 16bit istreamer and then 24 bit HU or will it be same, or even inferior to just single processing by the istreamer ?

if its better with twin processing and if AUX wont process it then is there any way to get this to work ? i need to control evreything from the iPad, except volume.

DerAlte you are absolutely correct. Just did PDi of my Ford Fiesta Classic LXi TDCi. There is provision for speakers on the front door, but it didn't look like a 6.5" diameter. So any idea about the size i.e. diameter of the housing for front speakers.
There is no provision for speakers on the rear door, but on the parcel tray. Had a look at it and there is space for installation of oval speakers.
HU is more or less finalized, but the speakers aren't. There are just so many choices, just not understanding which one to go. DerAlte can you suggest me speakers, as I think you know the sizes of the housing in the Fiesta Classic.
Another thing, I didn't spot the FM receiver on top of the roof of Classic, so does it means it doesn't have one or its embedded into the front glass??

[el lobo 6061]

Gurus of audio nirvana, I have finalized on the following components for my Fiesta Classic. What do you all suggest, should I go forward with this setup.
HU >> Pioneer DEH-6390SD. Comes with 3 pre-outs with 4V. Rs. 8990
Speakers.
Front >> JBL GT5-S205 Rs. 2490
Rear >> JBL GT6-S699 Rs. 4990
Does cables come with the speakers or do I need to purchase it, and if yes any brand typically, to suit the above system. Already blown up my budget of Rs. 12000. No subs and amps, because of boot space required. Gurus please advice on the above system, should I make any changes? Would be getting it done this coming weekend.

[DerAlte]

Check with @bass&trouble or @ramie pa-ji - they should be able to suggest 5x7 components to mount in the front door. There are models available from JBL and Infinity but probably not in India. There may be models available MTX, Kicker, JL Audio etc. IMHO the JBL S205 would be rather lacking in front.

For the parcel tray, 6x9 ovals should be good, but you may have to use a pair of MDF spacers.

If you are not using an amp, the existing wiring should be good enough for driving from the HU. Even the antenna connection should be there in the harness for the HU - the installation guy should be able to find it. The likely antenna locations could be (if there is none on the roof) behind the IRVM, on the rear glass (copper tracks) or even a location for a retractable old style antenna on one side of the boot.

DAC is Digital to Analog conversion. All the front/rear/sub processing happens in the analog domian. So it happens after the DAC. Hence if you use the iStreamer's DAC and feed an analog signal to the Aux in you will get front/rear/sub fading as the HU wil provide that in the analog domain.

If however you want to use the HU's DAC you will need to feed the HU a digital signal from the iStreamer. I dont know enough about the iStreamer to tell you if this is possible. I do believe that the P80's DAC should be better than the iStreamer's DAC. However I not compared them so my opinion is only a guess.
