hey everyone! I need Help... I now have a head unit. 4speakers. 1amplifier for the 4speakers. now what I want ?, I wanna know how to connect these without a car, at home... and make them work.like a little home stereo! plz I need help, I'm sure it isnt that hard... but I just dont know how.. really wanna make it work in my room!//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif thx in advance

You need a 12v power supply. It would be fine for the deck but if your amp has say a 20 amp fuse you would need a supply that can handle up to a 20 amp draw. The power supplies arent too cheap for the higher amperage ones though

ok cooll. but what kind of power supply.. i mean i have a computer power supply of 400watt! is it the same thing?! or there is specific kind of power supply for what i want

Any specific reason why you want to do this?

It would be easier to just get a receiver and do it right...

cuz I got those stuff but I dont have a car right now.. Im gonna get one later on but for now I wanna run them without the need of car, plus it would be a fun thing to do In the meantime, better than just seeing them stand there in my room

You'll want something like this for running a head unit and an amplifier. Depending on how much current draw the amp will create will tell you how big of a power supply you'll need.

I was wondering about Computer PSU's too... I have one that supplies 20A and they are basically just a 12v supply.

what exactly is current draw?!...I got the Polk Audio C400.4...

well there is 2fuse of 30A they say... so what kind of power supply is good for me?, my head unit has 1 of 10A

 

[DaveVT 10+ year member]

so figure a 12v 70a power supply or something close. 50 a would probably work

Most 12v battery chargers will put out 50 amps, this should work?

An amplifier takes electrical energy, processes it, and outputs it in the form of amplified audio. For it to take that energy it has to draw it from somewhere, right? How much energy a particular amp will require to create its output will be dependant on its design and how much amplification it was designed to produce. How little or how much energy it needs to draw from wherever is its current draw.

the manual for that amp on Polk's site doesn't specify average current draw so I wouldn't know how big of a power supply you would need for average listening. I have one 35a (like the one I linked you to earlier) and one 50a PS on my test bench and either one of them will power a 3-400 amp plus a head unit fine (assuming you don't max the volume every time its on)

It would 'work' technically inasmuch as it would provide the necessary 12v to your gear and it would operate. But there will likely be a really nasty noise in your output from the charger's power supply. //content.invisioncic.com/y282845/emoticons/sick.gif.b1847c8dabbfeeddbcf1a78052249e10.gif I mean nasty.
