Has any body else ever thought about using a car stereo in their homes as a replcement to big ugly stereos? Any way, just a thought. If anybody else had done this before please post your results.

Yeah... I was gonna do that.
I was thinking of using an old desktop PC case to put the rig in...
Pros:
--------------------------------------------------------------
(1) PSU for PC supplies 12v with earthing possibilities
(2) Drive bays to hold the car audio equipment
(3) Put amp(s) inside of case
(4) Expansion slots for audio out leads
OR
(5) Speakers built in to the case (2 6x9" would fit, right?)
Cons:
--------------------------------------------------------------
Heat?

you should have had me sit down first... "those big ugly speakers". i nearly fell!

how do you run an amp 12' volt in side your house? i have no idea now to do that,!!! does any one know, if yes please show me how!

build a big 12v power supply. like this one by rod elliot: http://www.sound.westhost.com/project77.htm
Yeah..he is planning to iuse that PC PSU to power his amp up...puts out a nice 10A at least...but not sure about interference though...it's an SMPSU...
Try using some chokes and a few caps on the output...would do good for the Amp at least...and use a BIG fuse...and be careful...I noe it's only 12V...but the current is crazy...
hey guys
why not just buy a 12V DC 1A Power supply. that shuld work. well it does in aus.

Cummon man...a crummy 1A wun kick it..especially for bass...you need at least 20A or something bigger...seend as much as 100A being used...

Rod elliot said his power supply should be able to go up to 500A with enough output devices.


why not get an electriction to wire it into your electricity (i.e. wire it into the mains). It shouldnt cost that much really (maybe it does?). just a thought.

12 in house?
Hi Jake,
I don't know about your local laws, but here in DK you won't be able to have anyone legally install 12V along with the "ordinary" power line.
Apart from legal issues, it's pointless to make the 12V gneration as part of the house's electrical sytem. The long leads from source to appliance will create immense losses (and be terrible inductances, considering that a lot of car stereo equipment has SMPSU's built in. (especially the power-amp's)
Generally, you will need to be carefull if you use a PC PSU. It can indeed deliver a lot of current (although some types have the most juice at 5V), but powering a SMPS from a SMPS can (in worst case) lead to faults in one or both components, mainly during turn-on and turn-off.
During turn-on, some car power amps draw VERY high peak currents, which may stress or damage your PC PSU.
During turn-off, your PC PSU may have temporary states of high output impedance. The SMPS of a car power amp may not protect against (negative) voltage transients emmitting from the SMPS to the PC PSU. At work I had this problem, where one SMPS fried another one during certain power-down conditions.

I have tried shorting a PC smpsu...it will just shut itself off...in worst case senarios...the fuse should be adequate to protect you...if you are feeling unsafe...build a BIG linear PSU~!!!
hey guys
car cigarette lighters only provide either around 20A or 60A (I can t remember 4 sure) This is all the stereos are wirred to.

interesting
Back in the very early 90' s I had fitting transformers installed in the distribution box while still living in Belgium These transfo's took 220 volt AC down to 12 v DC.
I did this in order to install the then very popular 12 volt halogen lighting. it took away the wall warts and even ceiling warts......
worked just fine and installing it was a piece of cake.

Hey, how about those big halogen light wall warts. They give out 12VAC and 6A. Shouldn't that be enough for a GC monoblock. You could go to IKEA, get the cheapest tracklight for the transformer, throw the hardware in the future use pile, and still have 3 spare bulbs for your current tracklights.
With two of them, each one DC'ed with a bridge into a 317/337 or 78xx/79xx to get a just under +/-12VDC supply?
