Investing in a good 4 channel car amplifier is a great way to get full-range, high-quality music from your speakers. The problem is that most individuals don't know what to look for in a low-cost, high-quality power amplifier. That's why we've put together this buying guide to help you find the best 4 channel car amplifier for sound quality around $100.
Resistance is a unit of electrical measurement that is measured in ohms. It's important since you'll need a powerful four-channel amplifier and high-performance speakers with resistance matching to ensure they function well together. You should avoid matching speakers that have a lower resistance than the amplifier's minimum resistance.
Of course, you'll need a spot to attach the amplifier somewhere in your vehicle, so its physical shape and size may be a deciding factor as you weigh your options. A larger vehicle, such as an SUV, will have more available room for an amplifier than a compact car, so choose the location and carefully measure the measurements. Before you place a purchase, compare candidate amplifiers to those specifications.
Classifications of Amplifiers
There are a few distinct types of amplifiers available for use in automotive audio systems. The fundamental distinction is that Class A/B amplifiers are less efficient than Class D amplifiers, although they have lower noise levels. Class D amplifiers, on the other hand, are more compact, making them suitable for cramming into tight locations below the dashboard.
The cost of a four-channel amplifier will vary based on the features it has. More complex amplifiers will have more features, hence they will likely cost more than a simple model with fewer functions. Remember that when it comes to amps, you get what you pay for, so if you choose one of the less expensive versions instead of the more expensive one, you might not receive an amp with as many features or last as long.
Today's amplifier technology is generally standard, although not all amps include the extra capabilities found in higher-end models. The noise level and filters incorporated in an amp's design have an impact on sound quality. You should consider purchasing an amplifier with crossovers, especially if they are adjustable. After the wiring is finished, the materials and design of the terminals are also vital for optimum sound and lifespan.
