Hi everyone



I am going to sell my car so I took off the car music system which is not going with car. Now as its lying in house I am thinking to use it at my home. The problem is to provide it 12v power. So I got an idea to use it with 12v AC-DC adapter(It has only 1.5amp). I used it and it worked but i thought I should check some more details before something goes wrong:S . So now after goggling around I found PSU too can be used as adapter has very low amp it might blow. I wanna ask can I use my Iball 400W Psu with it or I have inverter as well at home it has 135mah battery can I use it? Is there any sort of risk I mean can battery power kill a human being?



Music System specification-

Amplifier- Alpine 5400W max output.

Subwoofer- Bass tube JBL 1000W.

Speakers- 2x440W. 4ohm







Thanks

Most cheap PSUs are not rated for long-term continuous use on their outputs at full capacity.



A cheap SMPS will have real current capacity of about 5-6 amperes continuous capability.



Since you do not have *just* a small HU and are planning to run subwoofers and power amps, you will need a very beefy power supply. Something that can do about 30-40 amperes *continuously* on the 12V rails. (40 amps x 12V - 500 watt).



It may work, but it may be hazardous to the supply or the equipment or both. Be careful.
