How many amps are needed to power a car receiver and two 6" x 9" speakers?
I want to turn my old car stereo receiver and speakers into a home stereo. I know I need a converter, but how many amps should my converter be if all I am powering is the 50w receiver and two 6” x 9" speakers?
Standard car stereo deck needs only about 15 amps to operate, so find a good 20amp power rectifier and that should work fine.
By the way, for the price you’re going to pay for a rectifier, you can buy a half decent JVC or Sharp boombox that will sound significantly better.

What is involved in car audio? im brand new to audio and i want to put a new system in my car.?
So what do i need exactly, Please run it through Dummy Style, b/c when it comes to car audio i am just that, a dummy!
if it matters i have a 2006 Ford Taurus
Thanks!
radio- the brain of it all. dont skimp here, i recommend a kenwood excelon.
subs- the lows. what to go with here would depend if you want clean sound or retardedly high amounts of bass.
speakers- the mids and highs. stock speakers usually sound like crap, aftermarket makes a huge difference. if you can afford it go with a component set in front(separate tweeter and mid). go with normal 2way/3way(tweeter and mid are attached) in the rear.
amp- the muscle. this is what powers your subs, and if you have the money your speakers. a mono class d amp is best for subs. a 4channel is good for front and rear speakers. or you can find a good 5channel, it powers both the speakers and the sub in 1 amp to save space.
that covers the main parts. you also have things like the wires and things like that.

can my alternator handle two car stereo amps?
i already have a 600 watt sony xplod amp 4 channel hooked to four pioneer speakers. i just got a 12” pioneer sub. and i need a single channel amp. it doesnt have to be that powerful but ive heard that its bad for alternators to handle multiple amps. any input???
i would like to use around 300-500 watt amp for the sub. so my total power would be around 1000 watts.
You’ll have no problems.
"….. Your 600 watt amp (I doubt you have it go at that power, it would destroy the car, without saying anything about your ears and brain) at full power requires at least 50 amps, more since the amp is not 100% efficient."
Are you serious?? 600 watts would not destroy a car, or anything in fact. You won’t come close to doing damage to the car until 10,000 watts +. 600 watts is nothing, but I’ll say that amp probably puts out half that.

How many Volts, Watts, and Amps are in the Average Car Battery?
Hey Guys,
How many Volts, Watts, and Amps are in the average Car Battery?
Most car batteries are called 12 volt, although when running, can go as high as 14 volts. But the battery is still called a 12 volt system.
Amps are the driving force, and battery amperage can be as low as 200 amps for small cars, to maybe 1000 amps, for larger vehicles. The amps come into play when starting a vehicle, which can take 200 amps or more just to start, then the amperage drops and maintains a lower level, and the alternator keeps making current to replace that which is used.
During cold periods, the batter loses power, such as at 0 degrees, it has half of its power. And when it gets colder, the battery loses even more power, that is why it is so much harder to start a car during the winter.
Suppose you had a real cold engine, which took five times more energy to turn over because of the cold, the oil is cold and the metal is cold and stiff. Add to that a battery with less then half the power because of the cold.
You see, that’s the problem. That is why batteries are rated at 550 amp/hour or higher, to allow for loss during cold periods. A 550 amphour battery would only have 250 amps at 0 degrees temperature.
Watts are amount of power used, and is figured by mulitplying the volts times the amps. So if a car is using 5 amps, at 12 volts, to run the headlights, it is using 60 watts of power. (5 x 12). But most people think of batteries as amps and volts only, hardly ever think of watts. Headlights are rated at watts, such as high beam 55 watts, low beam 35 watts. So high beam would use close to 5 amps of amperage and low beams, about 3 amps., at 12 volts.

What is a good Car DVD Player for a rear-facing child?
We have a long 6 hour drive coming up next month and my 5 month old son hates his carseat. I have a feeling the only thing that is going to keep him happy during the trip is if we get a DVD Player for the car and stock up on Baby Einstein videos. He doesn’t watch TV otherwise so hopefully it will be unusual and entertaining enough to keep him happy! Anyone know of a good model that can be used with a rear-facing carseat? Thanks!
pretty much any DVD player will work, although I don’t approve of using a DVD to keep a child that young entertained in the car. I’m assuming your rear seats have head rests- try finding one with the velcro straps that are designed to attach to a headrest.

Looking for a remote control car + video camera + towing bed…?
I’m looking for a remote controlled car that either has a wireless video camera built in or one could be mounted, as well as a towing bed or have the ability to attach a walkietalkie/speaker.
Basically I need this for a school prank so please help! Thanks!
Try ebay. You can find just about anything you want there. Also check www.hobbytron.com, as well as Hobby Lobby and Michaels.

How many amps can i safely upgrade my alternator to?
It is a mazda 2.0 liter. Currently has a 70 amp alternator. Need to upgrade it for efficiency reasons. Wondering how many amps I can go up to
I am building an HHO generator and would like it to have 30 amps to be able to run it. Thus i would like to put about a 120 amp alternator on it. Would this be harmful
if you find one rated 120 amps make sure you have the proper voltage regulator for it or ask if it has an internal regulator

Does installing a sub woofer void/affect the warranty on my new car?
I just purchased a brand new Toyota Corolla 2009 and wish to install a sub woofer, i heard that modifications would void the cars warranty with toyota. Is this true for both minor and major modifications?
just take your sub out and anything that was changed in the installation process and then take it in for any malfunction, chances are they wont know

How do you calculate the amps in a capacitor if you know the voltage and number of farads?
A capacitor with 25 volts and 4,700 uf has how many amps, and how many amps would that be if I had four in parallel?
Capacitors don’t "have amps". You need to explain this better.
If you mean how much current you can draw from a charged capacitor, it depends on the load. Yes, if you had 4 in parallel, you would be able to draw more current, if the load were adjusted to call for that much current. If the load stays the same, then 4 caps would supply the same current as 1 cap, it would just last four times as long.
But the important part is that the current is NOT determined by the cap, it is determined by the load you put on it.

Good base techno songs for a sub woofer?
I have been looking for good base songs for a sub woofer that my cousin has in his car. We mostly listen to Lil Wayne and other songs that have good sound. Lately I have been looking for techno, rave, house, electronic, tektonic and many other genres of music with good base.
So if there is any good DJ’s please post them.
Thanks.
armin van buuren, hes been rated world number 1 Dj.
Please dont get Tiesto.
He is too overrated.
Trust me, i am a huge AVB fan..
AND YES, AVB IS THE F***ING Sh*T TO LISTEN TO WHEN YOUR DRIVING…
