the stock stereo unit is made to turn off while you crank the engine, the acc wire in your car goes from high to low to switch off all the accesories and give the stater motor as much current as possible.
When i was spec'ing parts i decided to go with the more expensive power supply (the opus) becasue of two reasons. 1 becasue power and power regulation is the single most important thing when your talking computers especially carputers and 2 because i didn't want to dick around with some circuit i had to build for the shutdown controler.
Boy am i happy that i did. Suprisingly the opus survived cranking in my car with no seperate tank circuit or anything. It is surprising becasue the stock stereo unit wouldnt survive a crank which i never noticed untill i began researching power supplys in the forum.
So i have the computer in a custom built box in my glove compartment. I have power run to the Power supply. I have a CDRW/DVD installed (looks factory installed) now all (out of the major comonents) I have to do is get the Lilliput installed. I started on it today and ended up breaking out the bondo. I will post some pics when it is complete (pretty soon i hope)

That isn't true for all cars. My MINI Cooper S keeps the radio playing when I turn it on from the accesory position.Originally Posted by Nic

I think what Nic was saying was that IF your 'stock stereo' turns off when cranking, that it's because the manufacturers made it that way. Not that all cars do the same...Originally Posted by Twostep
Why should it be surprising that the OPUS 90w survives cranking?? The input voltage range is from 7.5v to 18v! I can't remember seeing anybody on this board saying that any OPUS needs a seperate tank circuit!
Maybe you're mixing it up with something else?
For most people, the biggest selling point of the Opus is the fact that it is designed to survive a crank. A little bit of research here and you would not have been surprised.
Well i gues that makes sense then (stockl stereo made to shut off pourposely).
The only reason i was surprised that the opus survived a crank was becasue i was unaware the manufactures did this... Thus leading me to belive that if my stock stereo couldn't survive a crank that i probably would have problems...even with an opus.
I am fully aware of the specs on both popular power supplys around here.
The purpose of this post was provide some feedback to other people that are researching on what power supply to buy and to add some value to this board with my personal experience as i have not seen a definitive post that says opus will or willnot survive a crank. Correct me if i am wrong and post a link

I will go outside tonight and make a little video of my carputer with my 150W Opus surviving the crank
