Posted November 26, 201311 yr Here we go, starting the lightweight, simple install in the Miata First off some pictures of the car, keep in mind I was always too busy enjoying driving it to do anything else, like cleaning it Just after a wash, comparing it with a friend's Z3. Mock-up of the 7" tablet. Fits great in the scene Target for the entire system is under 30 lbs. That includes wiring, fiberglass, minimal deadening, speakers, amp, tablet and miniDSP.
December 6, 201311 yr Author Hah, yeah, I live in the land of vampires. And I've visited the "official" castle. Pretty nice crib No subs, the Extremis should do fine. After selling my tablet, I'm getting it back and the PPI 900.4 should be here before Christmas. miniDSP can wait, the PPI has some processing.
December 18, 201311 yr Author The amp weighs 2.5 Kg. Total target weight is under 10 Kg. Time to weigh the Extremis
December 18, 201311 yr The amp weighs 2.5 Kg. Total target weight is under 10 Kg. Time to weigh the Extremis What the hell is a kg? Pics!!!
December 24, 201311 yr Author I'll have to fabricate some sort of amp rack to keep the amp in place. Couldn't find a better place to put it. very short power wires FTW! It's TINY! 1 Extremis weighs in at 1.5 kg. So total weight with 2 Extremis and the amp is 5.5 kg. Dropping the target weight to 10 kg (22lbs). So still 4.5 kg to spare for deadening, tweeters, wiring, mdf rings, tablet and minidsp.
December 24, 201311 yr Really like my 900.4's small enough to install in a glove box of some cars and put out respectable amounts of power and sound clean doing it.
December 27, 201311 yr Author Started the amp rack cardboard mockup. It will be built it out of 1/16" thick flat stock, with speed holes to keep the weight down. Going to use the battery hold-down bolt for one of the supports since it's convenient. Yesterday I broke down and ordered a Nexus 7 (2012 model)
December 27, 201311 yr permanent mount for the tablet or making a dock? I was thinking about modifying this dock (or using pins) for a dock set up http://www.amazon.com/gp/product/B009UQZPA0/ref=s9_hps_ft_g147_ir01?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-3&pf_rd_r=1EQF9EDV8JRP95JWD4XX&pf_rd_t=1401&pf_rd_p=1705902322&pf_rd_i=1001023771
December 27, 201311 yr Author Tough to fit a dock, I'll mount it "permanently" and just run wires with plugs. One big problem is the volume control, if I don't have access to the rocker switch, the volume control will have to be somewhere on the screen. Some tablets have it there. And I will have to figure out a way to access the power button.
December 27, 201311 yr minidsp has a volume pot. for power im guessing there's a way to boot when vehicle is turned on. i started a mount but scrapped my plans. buying a new car this monthhttp://i277.photobucket.com/albums/kk69/killwish/photobucket-29702-1376162086652_zps2b8dd230.jpg Edited December 27, 201311 yr by lithium
December 27, 201311 yr Author I want to keep it on all the time and just have it turn on the screen miniDSP sure has one but first iteration of the system will be using the PPI's on-board processing. So I'll have to figure out a way to control volume. Mounting it nicely is going to be a pain in the butt
December 28, 201311 yr the battery life is pretty solid so I bet it would hold charge for several days maybe over a week. the ppi unit looks pretty good, i went the cheaper route with two 2x4 units. maybe you'll be able to do some external volume control with a rooted os. iirc sean found a way to do steering wheel controls which would include volume i would think... edit" mount idea http://www.diymobileaudio.com/forum/build-logs-project-install-gallery/157938-2013-wrx-nexus-7-install-no-hu.html Edited December 28, 201311 yr by lithium

And I will have to figure out a way to access the power button.Are there steering wheel controls? If so, it is easy enough to get them to talk with the Nexus. Or perhaps any other button in your car. Can also root it with Timur's kernel so a volume control is in your task bar at all times. Just + - but it is enough. Power control on that unit is EASY to reach if you pull the rear cover and can then make your own. Or use the kernel above to automatically unsleep when it see's power. Usually about a 2 second boot from sleep. Battery lasts about 10+ days with the car off in standby as well. As long as you drive once a week you'll have instant startup nearly. And definitely permanent mount. SDR Touch and some adapters will let you get free FM over your car's antenna. If you want peripherals, before you go buy some let me know as I may go a different route and am all set up to do it. I just have WAY more screen real estate space than the 7 so I'd like to go bigger. ONLY the Nexus 7 (2012) can boot instantly via rom, charge over USB & use a USB hub all at the same time....unless someone has hacked something else in the past two months which I don't think.
December 28, 201311 yr Being the outside of the screen is flat and style of mount that sandwiches will work. Would have been the easiest screen mount in a cayenne. 1 piece of wood, routed, then cut and 4 holes drilled and stock mounts would have worked.

No need for steering wheel controls With the current kernel, in developer mode I could set it to never sleep when charging. And it goes to sleep 15 seconds after I stop the charge, so all is well on that side. From what I could find, the volume and power buttons are on a separate PCB, connected through a ribbon cable. If I take it apart I can move it where I want and problem solved. For permanent mount I need to figure out a cover to go over it, with magnets, so that everything is stealthy. Keep in mind it's a rag-top and a tablet in the dash screams steal me. A black plastic cover with the Mazda logo screams boring Please let me know what peripheral setup you have, if you're selling, I'm buying. Not sure I want FM (antenna mast is broken and I'm not spending $50 to replace it at this point). But charge over USB and using a USB hub is mandatory. Plus I need to find a cable with a 90 degree plug. People on head-fi were dicking around complaining that the DAC is crappy and there is a tutorial for using a USB DAC, did you ever get to listen to the headphone output?
December 28, 201311 yr Author In other words, progress on the amp rack...hooray speed holes I ran out of gas for the MIG some time ago, so no welds until I can get gas In the meantime I can finish off all the pieces and build an mdf amp mock-up to keep things in place when welding.
