Well, I'd like to know what I would need to set up my head unit in something other than my car... Like in my room. Sounds stupid but I'd like to see it done. What will i need/need to do to make it work?

The problem with doing this is powering the head unit and amplifier(s) is having a clean source of 14v DC that can provide enough current to what you're running.

 

use a 12volt power supply. That's what most companies use to run their demo walls. Those ones are around 50 watts RMS and 200 peak, and I know circuit city also uses Optima mini-Red's to help keep the power from the supply from dipping too far.

Or you can use a battery charger like I had done when I jerry rigged the setup i was screwing around with in my room.

 

id go with a battery charger to . i used to use them to test stuff with, it allways worked well

 

Any info on actually doing the whole "hookup" I really have never done anything more than install my own head unit in my car.

 

mayeb try getting two distro blocks , then splice the mem and the acc wires from the headunit together and run the rest just as you would in your car

 

i need more info! remember, im a total a/v noob. i just think this would be a cool thing to do since im not using my headunit in my car for a longggg time. thanks for the ideas so far... just need the simplest solution.

 

just a headunit and highs or head unit, highs, amp , and subs?

 

its just a headunit and highs, no amp, no subs. it doesn't need to be anything complicated... just need to power the headunit and connect it to some misc. speakers.

cheapest and easiest way to do this would be nice. tia

 

radio shack a while back had a 12v converter take a look on their site.

 

I love being right

3-Amp Regulated Power Supply

$39.99 Brand: RadioShack
Catalog #: 22-504 Model: 22-504

 

thanks

edit: bought this today



thanks to the post above i went to radio shack and found it.


tomorrow i think i will build something to attach it to my desk along with 4 speakers.

 

Thats a pretty cool idea. So does this Radio Shack thing just plug into the wall, then you hook it up to your head unit?

3 amps is small imo, if he is going to drive the speakers off that headunit also. Do they sell a larger one 5-10 amps?

 

LOL, I did this a few years back. I was bored and had an extra system laying around, so I hooked it all up....It bumped pretty good up until my battery died. I wish I took pics of it

My Setup:
-Sony Xplode head unit
-(2) JL audio 10's
-(2) Fosgate 10's
-(1) 500 watt Fosgate amp
-(1) 800 watt Logic amp
-(1) 18 wheeler truck battery

 

dont forget to post pics eL

how to?

Since you said its only gonna power the mains and not be pulling any bass, 3 amps should be ok. The player and controller itself will only draw maybe 500mA, and you should be able to get descent volume in a small room using only 5 Watts or so (trust me it doesn't take much power to be loud if your not pushing bass). The amplifiers in most radio clocks are about 0.5 - 0.7 watts.

Also that rating may be with a constant or square wave load, the sine wave that music follows is ussually very much more easier to deal with than constant or square waves.

A 10A regulated power source will cost quite a bit commercially made like $60-$100. Even if you made it your self you would be looking at $50 and 10A could drive a stereo pair of 60-100 Watts RMS, and were only dealing with a head unit that probably puts out at best 20W RMS.
