When shopping for a car amplifier, there are a few basic questions that everyone has and a few use-cases that typically come up.This car amplifier buying guide will help answer those questions and get you started on the path to better car audio sound. Once you know the real numbers you will be able to tell if that “1000 watt” amp is really the deal that you thought it was. Also, unlike 2 or 4 channel car amplifiers, 5 channel amps may contain a mixture of amp technologies. We show you what is real. Many car audio stereo receivers on the market feature an integrated and user-adjustable crossover system, designed to route certain sound frequency ranges to specific speakers connected directly to the head unit, or through low-level outputs designated for external audio amplifiers… The technique has become very popular among many car owners because it allows amplifiers to send out a more powerful mono signal to the subwoofer or speakers. We match your amplifier to your speakers or subs and create a perfect fit. The monoblock amp can generate a single power signal and it is ideally matched to the low frequency design of a subwoofer. A 5-channel amp, however, can do it all. We are at our second-to-last article in our car audio amplifier specification series and this time, we are going to talk about Class AB amplifier crossover distortion. Which Type Of Crossover To Choose? Car Audio Amplifiers . 5 Important Specifications To Consider When Choosing An Amplifier At Cambridge Audio, we don’t go in for unnecessary complications. At this gain position, the 9vrms head unit will drive the amp to rated power at a very low volume control position. Bridging an amplifier refers to the process of combining two of four channels into one or two channels with half the ohms. The amplifier is featured in this article, the third in a five-part series about the components that make up a modern car's stock, factory-installed audio system. The 1.5vrms head unit can drive the amplifier to rated power and would be an acceptable gain position for the 1.5 volt head unit. Hook each channel of the amplifier to a single speaker or speaker pair in the case of component speakers. For example, while some may use class A/B for the 4 main channels, class D is often used for the 5th channel for efficiency and reduced heat. The purpose of a car audio amplifier is to take a low level signal from the source unit (head unit, radio, etc.) Amplifier Bridging. Actually, the couples of subwoofers can be wired together in order to form a single mono amp for obtaining the most effective … As you can see, the gain controls match the head unit to the amplifier.

Amplifiers aren't always designed to turn a small voltage or power level into a bigger one; sometimes it's the current we're interested in instead.
