Mods you can move it if this is too off topic for audio.

Using a car stereo, indoors.

I am going to be honest I have only a basic background in electrical engineering from my 3 years of physics, what I do know from it tells me that this is possible but what I don't know is keeping me from being able to complete it.

Here's what I know I need to make it work:
Amplifier (Have)
Speakers with enclosures and sub with enclosure (Have)
A car to pull these from that isn't used but 1/2 times a month (Have)
110VAC to 12V DC Power Supply (Don't have)

Here's where I need the help from somebody with more knowledge/equipment available to them. I know that I need the power supply to be able to make the DC amp run inside what I don't know is the ruggedness that it has to be. I truly have no idea what the average current a 1000 watt sub amp draws from the 12V system. I am wondering if anyone has any clue how much amperage is drawn by a 1000 watt amplifier at peak. My other problem is that I have no multi-meter to go test my system.

i was about to tell you to just use an amp meter, but your last sentence says you don't have one, i'm just not entirely sure this could be done because i'm not sure how you would wire the system to a power supply, i am in college fo rmusic and audio, my classroom is a studio, so i mainly work with big speakers, console, mics, amps, stuff liek that, but its all generally the same, like i said your big issue is getting the power supply, i doubt in anyway its going to be easy, i'm thinking lots of custum wiring and splicing and tapping, and you should get a volt and amp meter, unless you want to see some cool metling or sparks

 

The way I see it is if I can manage a power supply from the science dept here ::looks around suspiciously:: that would have a high enough amp capacity/fuse then I would be able to work everything else out (I can do the wiring after that) or if I can figure out what amps I need I can try and get my engineering major of a roomate to fix something up .... though he is optics and not electrical engineering ... basically I just need one of those big 12V power supplys like they use in the labs... just real big I think...

 

i doubt it, theres little boxes called phantom power, they suppply 48 volt dc power, and they arent very big at all, maybe if you get an amp meter, then you'll know, heh, but i mean, a 12v power supply shouldnt be hard to find, probly wouldn't even cost more than $100

 

hmmm i was thinking last night that a transformer out of a microwave oven (an old one) would do it. Question is has anyone tried this, or does anyone in the Rochester area have an old microwave oven that doesn't work/don't need anymore?
