12s in 4th order VS 15s ported
the sundown wont net you any audible output gains. theoretically it would 1.5db but you wont see that much.

nexus 7 gen 2 now works with timurs. nothing for the 10" iirc. I'm curious if you can charge via pogo on the nexus 10 and still access data over usb. edit: nope

wow, US acoustics is making amps again. http://usacousticsca.com/index.html strange names for the amp models. I picked up a couple of the usx amps from this guy on ebay before. http://www.ebay.com/itm/US-Acoustics-4-Channel-Amplifier-/171370794449?pt=Car_Amplifiers&hash=item27e67ecdd1

http://www.mini-box.com/M2-ATX-160w-Intelligent-Automotive-DC-DC-Power-Supply seems you can set that kind of functionality with this and maybe settings change in windows. ignition on - pc boots up, ignition off - pc hibernates or sleeps or whatever.

dont think a delay would be needed.

Welcome to the IHoP v.2
Not trying to be a smart ass or anything but the description says: "You can shorten system boot-up time to 2-seconds* for a smoother user experience under Windows 8, and even previous versions of Windows." So I'd say around 2 seconds. You could probably use the sleep / stand by function to shave off a little more time but more importantly your stuff would still be open from the last time you shut it off. They say that about their BIOS meaning you may need a faster mobo/pc or the like. That is how I found it first, but If it power cycles it'll be hard to resume...or it'll kill my battery? Thinking headunit for the Esky... hibernate would work. Hibernate on the power being pulled? I'd need some delay circuit?mp3car is such a fucking fuck show you can't find donkey dick there. Frustrating. it just writes the current state to harddrive and shuts down. then boots into that state the next time you turn it on. http://www.pcworld.com/article/2016932/how-to-enable-hibernate-mode-in-windows-8.html

12s in 4th order VS 15s ported
nope, either try a high tuning in the current box or save for 15s.

High QTS Q12 in a ported enclosure
i would look at other options first. moving the enclosure around in the trunk. for example, move it all the way to rear of the trunk, firing towards the license plate. reset the gainchange xover pointseq the response (no boost. eq down the high end)add polyfill if you haven't already

High QTS Q12 in a ported enclosure
the box will be completely different than the recommended as they only correspond to the non-high Qts version. Whats the issue with the current sealed enclosure?

12s in 4th order VS 15s ported
the ratio business is also BS. what are you trying to achieve?

12s in 4th order VS 15s ported
nope just some bullshit that spread around the internet.

12s in 4th order VS 15s ported
12s in a bandpass wont gain output over a conventional ported box.

10" sub for sealed box .5-.7cu ft, 5.25" deep or less.
sounds good. i would pick up some CCF to decouple all the panels around the sub enclosures. i assume they'll be prone to rattle the most.

10" sub for sealed box .5-.7cu ft, 5.25" deep or less.
this is what i ment by going to the spl display. i threw in that shallow alpine type r, which isn't that great it seems, and a dcon 10 in a ported box. when you include cabin gain the frequency response of the ported sub will have a hugely exaggerated low end (so people enjoy this). while the sealed systems will be closer to a flat response. i modeled the jbl gto 8" (2 per box) vs the sundown and its pretty much a wash. less than 1db difference isn't audible. someone mentioned a 15" sealed in the spare tire well. here is a xcon 15" on 1500wrms in 2.2cuft VS 2 sd10-2 on 1000wrms the strength of the xcon 15 is that you could tailor the response to your liking and still have spl to spare compared to the 10" options.

10" sub for sealed box .5-.7cu ft, 5.25" deep or less.
I'm wondering if I put the sub in properly. So I used a tutorial from an HT forum and put the info in again. My first problem is Sundown doesn't list SD. Everything else seems fine except VAS, for some reason it calculates it at .06 L. Second problem is I'm not sure which type of crossover to select for the lowpass filter. Butterworth, linkwitz? I'm assuming I'll want to select 4th order. Third, how much of a difference will cabin gain make? I'm looking at .45-.5 cu ft net for each SD-2 10 D4. These will have as much power as they need, with 1500 rms available. Here's the graph with both input methods and thiele listed. And 4th order Butterworth @80hz filter on both. vas is given, so if you have xmax it can calculate sd. cabin gain is basically an effect produced by relative small size of the car's interior which boost frequencies below a certain point by about 12db/octave. http://www.glasswolf.net/papers/xferfunct.html i plugged some subs into winisd. i'll post them for you in a min.

go to the "spl" graph and compare a few options with the amount of power they're would get. you can knock down the high end to flatten response. cabin gain will help as well.
