Best Amplifier Review

Overview

Many believe that their vehicle’s OEM stereo has sufficient power, or that their new aftermarket stereo that puts out 50 watts per channel is enough for a great sounding system. But, the reality is that whether it’s an OEM system with ‘300 watts’ or an aftermarket unit with 50 per channel, most of wattage ratings are peak and don’t represent the true output of the system. For example, a 50 watt per channel aftermarket stereo might actually only be pumping around 15 to 20 watts to each of your speakers when all said and done.
To power your speakers (aftermarket or not) with the correct amount of power can mean a WORLD of difference to the performance of both subwoofers and speakers alike. You may have the highest performing speaker or subwoofer but without the power, it ultimately means nothing. Don’t let power be the bottleneck of your system. Get an amp that provides your speakers with the power they need to produce crisp and clear music, whether your using high performance component speakers, subwoofers or OEM equipment. And if you are going to add a subwoofer, an amp is an absolute necessity.
Here’s a list of 2015’s best rated series amplifiers for your car to help you match the ultimate amplifier to your car’s stereo, speakers or subwoofer.

#3 Rockford Fosgate Prime Series Amplifiers

Rockford Fosgate Prime Series Amplifier Review
Rockford Fosgate has built a reputation for manufacturing high-quality, high-performing mobile audio equipment. Their Prime Series car amplifiers are among their top amplifiers, built on a durable platform with an innovative and sleek-looking design and reliable, clean, and powerful performance.
The Prime Series amps were designed and manufactured with several of Rockford Fosgate’s patented technologies. DTM (Tynamic Thermal Management) is their 3-stage thermal system that distributes forced air to evenly dissipate heat across the amp. A proprietary process called MEHSA allows heat to escape more efficiently from the MOSFET devices to the heatsink. And Differential Input reduces electrical distortion and interference that could be transferred by your input cables. This combination of proprietary technologies and fine-tuned features results in an amplifier with minimal distortion, incredible heat distribution and control, consistent high-power output, long-term reliability and most importantly high performance. The Rockford Fosgate Prime Series amplifiers are highly regarded in the industry, and for good reason.
