In this buying guide to the best car amplifiers, we discuss the different types of crossover and what exactly CEA-2006 compliance means for amps. We think these two characteristics of an amplifier should ultimately determine what amp you buy.
There are two basic types of crossovers: active and passive. Active crossovers require power and ground connections, while passive crossovers don’t require power at all.
The Consumer Electronics Association (CEA) is an independent organization that tests electronic products against manufacturer assertions for common characteristics of a specific product. CEA-2006 is a rating standard created to help consumers compare different amplifiers. A CEA logo on the side of an amplifier’s packaging means it is CEA-2006 compliant.
The two most fundamental qualities of an amplifier are its loudness and how high a quality sound it produces. Due to this, CEA-2006’s principle ratings for car amplifiers are Output Power and Signal-To-Noise Ratio. Without a car amplifier receiving official CEA-2006 compliance, the true quality and loudness of sound are unconfirmed and somewhat unknown for an amp.
To select the five car amplifiers in this review, our team searched Amazon and Advance Auto Parts for top products, looking at factors like customer ratings, price, superlatives, and Prime shipping eligibility.
According to thorough and unbiased research conducted by our team of experts, the Rockford Fosgate R500X1D is the best car amplifier. However, any amplifier featured in this review will be of high quality.
A good car amp typically costs between $200 to $450. However, good car amplifiers can range in price even further than that, as there are many car amps that cost upwards of $450.
A general rule of thumb for choosing a good amplifier is that it should provide anywhere between 1.5 to 2 times the continuous power rating of your speaker. Doing this will ensure that your speaker has an ample amount of power.
