The best way is to use an old manually tuned receiver.

Power supply for car stereo amp.

In this video i ll show you how to use a standard car amplifier and hook it up to your home with a power amp. A battery charger is generally unregulated. We ve talked about car audio amplifier features and specifications at great length but up to this point we haven t discussed how a car audio amplifier works. A dc power supply is used in place of a 12 volt battery when you need to operate car audio equipment and the only source of power is the mains voltage ac wall outlet.

Adaptation computer power supply for car amplifier. This is different from a home electrical system which uses alternating current ac and provides 110 to 120 volts at a lower current. Adaptation computer power supply for car amplifier. Car amplifiers are designed to use the direct current dc from the car s battery and alternator for power.

In this article we ll provide a simple overview of how the power supply in your mobile amplifier can take the 12 volts supplied by your electrical system and convert it into a much higher voltage to drive your speakers. To run a car amp from an ac circuit you must first convert from ac to dc power. Match the power requirements of speakers with the output power of the amplifier or receiver. This type of power supply is similar to a battery charger but has much better manners.

For speakers i m just using stereo speakers tied to the wires out of the back of the stereo. My suggestion is technically correct regarding selecting power supply for car amplifiers and there s no doubt about it. Power should equal the impedance rating for each of the speakers.

Purchase a power supply that s in your budget. The manual specifies 12v as the operating voltage for the amplifier so the power supply should be rated at a fixed 12v regulated and the current is immaterial and could be anything higher than 10amps upto infinity. Speakers require more or less power than others loudspeaker sensitivity is expressed in decibels which is a measure of how much sound output is produced with a specified amount of.
