Can anybody tell me what I would need to power my car amplifier in my house? I'm not sure what other information I need to give, but basically I want to power two speakers in my MAME arcade cabinet using this car amplifier.
I figured I'd use the amplifier if possible because I have it laying around just collecting dust the way it is Can I buy something from Radio Shack or should I get something else? Do I need anything else to hook it up inside?
I've thought about doing this before, and posted on Ars about it. I never really got anywhere due to incompetence and laziness on my part, but i've seen it done by a friend who used a computer power supply to power the amp. So it is possible, i'm just not clear on the specifics.
A friend of mine bought a 12V supply for setting up his car stuff in the house. He wound up with a large, heavy power supply that cost a couple hundred bucks.

You may be able to get away with a computer psu, but they dont put out close to 15 amps on 12V as far as i know. Are there any cheaper alternatives? For that price I can buy better PC speakers with built-in amplifier and take it apart I'd still really prefer using the car amplifier and real car speakers though Anything cheaper I could set this up with? Originally posted by FooF: Car amplifiers can handle changing voltage levels fairly well.
A car's electrical system has lots of surges and brownouts. A car amp will be pretty tolerant of poorly regulated power.
Their power ratings are usually at You could probably also get away with less than 15 amps.
Can you hook up a car amp in your house be pretty loud before you were using that much current. I'm just going to use an old kenwood integrated amp in my cab. I asked around, and got it for free. Ask around, check thrift stores, and you can probably find something decent that runs on AC for real cheap.
AC to DC conversion isn't efficient or cheap. I understand you want to use something collecting dust but if the cost to get it to work is more than the product is worth then its a definite don't dust it off situation. I would think a computer power supply would be sufficient. Sorry but "a cheap battery charger for a car" will only have minimal filtering.
Don't use a battery charger as it will hum like a bitch as it has no filtering. Originally posted by DriverGuru: Properly ground it, and there will be no hum. So thenb it should work for everyone else? Properly ground it, and there will be no hum Ground has nothing to do with the lack of filter capacitance.
Thats funny, thats NOT what the crossover is for.
At least we know your level of expertese now. Ground has nothing to do with the lack of filter capacitance. Your new, now you know better. In addition to working for a car stereo shop in the past, i think you should treat my responses with a least some level of respect.
In addition to this, if you're going to call me stupid, I suggest you not misspell expertise. I know what you mean, but this sentence makes no sense. Originally posted by izzelsizzel: THe only way a crossover will help with AC hum from an unfiltered power supply is if you set it up to throw away everything below Hz or so. This is probably NOT what you want for videogame sounds. No, not just 60 Hz - the ripple from a full-wave rectifier operating under load has a LOT of harmonics in it.
The answer is capacitance, and lots of it, at the rectifier output. Ok, I have some news However I'm wondering if by doing this I'm somehow damaging the amplifier or the power supply.
Also, do I have everything wired correctly?

You shouldn't be damaging either component. If the PSU is relatively modern, it will automatically shutdown if the amp tries to draw too much power which should
