Can a car battery charger be used in the place of a car battery eleminator to run a car-audio-amplifier?

I have an amplifier connected to the battery in the car to run a woofer. I would like to use this amplifier in the house. This is possible with a battery eliminator - one end of which is connected to the domestic mains and the other to the amplifier. Since to get the eliminator of the correct rating is very difficult, I want to know if I can use a battery CHARGER instead of the battery eliminator.|||Hi


A battery charger is basic in it's construction it has no power regulation, it is also going to give loads of mains hum on the audio as well as the bass frequencies.


it contains not enough power for most amplifiers.


so it would sound like rubbish and could blow up if used.|||The answer is not not suggestive of strong technical capacity. The question was through in all the respects with the additional details. The contributor may kindly go through the question in its entirety and could then revise the answer. A battery would be charged full with a properly rated charger.

|||No you can't. The charger produces very rough DC and the amp will buzz louder than the music. It can be done if you use the charger connected to a spare car battery which supplies the amp, but that's not really a domestic option|||the problem with that is that the battery charger still does produce some ac voltage. a diode could be used to rectify that voltage but then the voltage will drop some. find a system that is set up for that application.|||No, it is not designed to give the required amperage constantly that the amp would required, it is a charger not a power unit, very different things.|||no, you will need to get a 12v power supply which runs of mains and that it has enough amps to power your woofer. if you are uk based Maplin have them.|||No, you can't do this,the amperage would be far too high.


I have made the same mistake before.|||Hi,





You need a steady 12v dc power supply with more amps try a 12v CB power supply etc.





good luck.|||No, the amperage would be far too high.|||No way
