  Hi everyone,

  I'm planning an install of a Galaxy 10.1 installation and wanted to get your input...

   

  The tab will be my only source unit, I will be installing a JL Audio HD5 amp, Morel 6.5 Ovation components and i got a Cerwin Vega Sub.

   

  I have to main concerns for this setup:

  1. I want to use an active crossover

  2. I want to send the audio signal from the tab via bluetooth (so i dont have to plug any wires everytime I get in/out of my car)

   

  For the bluetooth I plan on using something like this and plug it into my crossover after pairing it with my tab ofcourse. My crossover will then be connected to my amp, and my amp will wire out to mids, tweeters and sub.

   

  Other concerns I have:

  1. Master volume knob - this is pretty much all I would want up front, I was thinking of getting a preamp equlizer up front and use that for volume control.

  2. This is a bit tricky, not sure if its possible at all without getting an additional component - getting the music to mute when I recieve incoming calls.

   

  Another question I have is whether I really need a crossover if I get the preamp equlizer?

   

  Once I get all these questions cleared up I'll get into installation and I'll be more than happy to upload pics/vids of the progress as I go along. 

  I will be installing this system in a 2010 Seat Ibiza Sport (none of these are sold in the states as far as I know).

   

  Looking forward for you input!

  Thanks!

  Here's a quick set up of what I'm doing. Same tablet.
  
  
  
  I'm using the tablet and the 7" dock, which has the HDMI output on it. Then I'm swapping the cradle of it for the 10.1 cradle. They just pop off the bottom piece and snap back on.
  
  I'm using the HDMI output to an Octava 1 x 2 distribution amplifier and converter. It takes the HDMI signal and splits it up to an analog signal, optical signal, and is used as a splitter for HDMI outputs as well. I'm using headrest monitors in mine so I'll use the HDMI connection to the headrest monitors for video feeds.
  
  For yours, if you're not using any headrest screens you can go with this piece in stead.
  http://www.octavainc.com/HDMI%201x1%20Audio%20Converter.html
  
  It basically does the same thing except it has one HDMI out instead of two, which you won't need if you're not doing the video monitors. The other one just has a splitter built in, is the only difference, which I need.
  
  Next I'm running an analog signal and an optical signal to an Audison Bit One processor (active crossover). This has everything you're going to need for your set up. It's got a remote for you to run up front with a volume knob, and settings galore. It's the ONLY thing you'll need for your setup. It's a little pricey but after you buy all your other crossovers and equalizers and all that stuff, you might as well have bought this. It's a piece of gold wrapped in a black box!
  
  Power, I'm going to hard wire a samsung car charger and that will plug into the cradle cause you need power for the HDMI source and as well the tablet will charge as long as it's in the cradle.
  
  For the power to the Octava piece, I'm using a DC-DC converter which will power up to 5v which is what you need for the unit. Clip the plug off, and wire up the converter. Make sure you do a test to see what is ground and what is positive.
  
  Then, just hook your amps to the bit one, and remotes of the amps to the bit one, and then run the bit one off the ignition with a switch up front in case you want to turn it off, like you would use a remote wire for a head unit. Same theory, just as a switch instead of the off button.
  
  I guess I should get on making that article up huh!
  
  Here's a quick bench testing of the set up. It will kind of go through how it's done. Although it's cut off at the end you get the idea of how it's run.
  
  
  
  Let me know if you have any questions.

  Thanks for the quick in detailed reply...
  Do I really need that Octave distribution thingy? Can't I connect the tab directly to the bit one? and what about that bluetooth connector I mentioned?
  I'm low on cash, just the bitone alone would set me $800, the tab is another $600, amp, speakers, wiring, etc.
  Is there a cheaper alternative to the bitone?
  Thanks!

  Let's see here, it really just depends on what you're after.  If you have the tablet or it's a priority over everything else, what you could do is just simply use a 3.5mm to RCA adapter.  You can either go right out of the tablet, or the docking station (the 10.1 only) has the 3.5mm jack out as well that you can use if you're going to put it in the dash.  From there you can just go into anything.  You can use any processor.  You wouldn't need the Octava box at that point.  

   

  However for the best sound I highly recommend the HDMI output from the docking station swap, or the tab adapter I talked about above.  Using that, you would for sure need the Octava box, or something that will conver the HDMI signal to an analog or digital signal.  I tried two converters, the Octava which worked with everything, and a different one I bought off Amazon, which did not work. I believe it was only about $50.00.  

   

  This one:

   

   

  To which I was going to do an adapter with to go from a VGA out to RCA for video.  

  

   

   

  Now if you're not doing video, this may in fact work for you.  I believe someone on here used one of these in a similar set up, and it worked for him.   You can see there, in the picture above, that it has analog output, and it also has the digital output.  I did not try those, but I still have the unit and will be happy to try it and report back as well.  I do know, however, the VGA adapter that is pictured DOES NOT work.  It just doesn't for whatever reason.  I had analog headrest screens before which was why I was trying to go that route, and after doing several hours of research, I ended up with the end result of; it just won't work with an analog video signal and the HDMI.  There may be a way to get it to work, but I was ready to move on.  

   

  Even with this thing, you could use any processor.  I hope that helps! 

   

  I'll see about maybe doing a set up tonight with this converter, as well as a better set up with the Octava set up.  It may not, however, have video as I don't have my HDMI screens yet and my tv is too hard to take out to the garage!  LOL!

  Can you recommend a couple of other processor alternatives?
  Why is the HDMI converted to analog better than straight analog?
  I think I'm gonna send the sound to the processor via bluetooth, no wires running and it sends a digital signal as well, no need for a conversion either.
  And I won't be needing any video either.

  To be completely honest with you, I just did the research on these two products. I can't really give you a specific reason why the HDMI converted would be better than the 3.5mm analog, but from what I've been reading and listening to people say, the headphone jack is a terrible way to get audio with any type of decent quality, to anything other than headphones. I've not 100% tried this theory, but with me using video screens, I needed the HDMI signal anyway.
  
  I'm not technologically smart enough to answer any of those types of questions with any confidence or 100% truth. But if you come across some specifics to it, I'd love to hear them and I'm sure so would others. I'm in for making this whole thing as dialed in as possible. So I welcome, and am open to, any help or insight you or anyone else would care to provide.
