The dual “Sierra” feedback system decreases distortion via signal correction. Premium capacitors and high-efficiency transformers are used in its construction. When it comes to building a quality six-channel amplifier, Alpine borrowed a few technologies from its older brother, the X series. Hi-Res certification means your music will have enhanced realism and depth that you can’t just hear, but also feel. This feat allows this amplifier to proudly wear the Hi-Res badge on the packaging. First, the R-A90S has the capability to reproduce high frequencies up to 45,000 Hz.

This amplifier is part of Alpine’s venture into bringing back high-quality, high-resolution products. Kicking off our recommendation list for the best 6 channel amp is the Alpine R-A90S. Keep in mind that six-channel amplifiers are also extremely beneficial in marine and side-by-side audio installations. While those are just three common examples of the use case for six-channel amplifiers, there are plenty more reasons and methods that I didn’t list. Imagine running front speakers, rear speakers, and a subwoofer all off of a single amplifier! This is an example of how great and versatile a six-channel amplifier can be. The front components are run passively using a crossover (usually included with most component speakers), the rears have their own channels, and then the final two channels are bridged to power a single subwoofer. Front 2-Way Passive + Rear Coaxial + Subwoofer System: In this example, there are six interior cabin speakers and a subwoofer.This is a front stage + rear fill setup where the front and rear speakers are all individually powered. Front 2-Way + Rear Coaxial System: In this example, there are four front speakers and two rear speakers.This is the holy grail of what we call the “front stage” in car audio. Front 3-Way Active System: In this example, there are six speakers for your front stage and you want to power each speaker individually.When would you use a six-channel amplifier? I’m glad you asked! Here are a few scenarios that come to mind: I’ll get more into the crossover networks and other audio features in my recommendation list below.

As DSP technology has emerged and become mainstream, many six-channel amplifiers will have electronic crossovers built in and accessed via mobile or desktop software. In most cases, six-channel amplifiers will have onboard crossover networks, generally split into three sections covering each pair of channels, respectively. In some rare cases, there will be 1 or 8-ohm ratings as well. Generally, most automotive six-channel amplifiers will have a 2-ohm or 4-ohm rating. When bridged, the amplifier will make more output per channel, but as a compromise you will lose channel count.Īlso, keep in mind the impedance and how that will affect power output. Keep in mind that many modern six-channel amplifiers can be used in stereo or bridged. Specification wise, you’ll want to consult the owner’s manual, which will tell you how much power is produced per channel and at what impedance. If you’re savvy, you’ll also be able to decipher the amplifier channel count based on the part or model number.Ī six-channel amplifier has six dedicated outputs. That information is also provided on the box and in user manuals. When you’re shopping for a car amplifier, the output channels are indicated by the number of output speaker ports on the chassis. That created a new demand for amplifiers that have even more channels! What is a 6 Channel Car Amplifier and When is it Applicable? But, as I stated above, the increase in vehicle speaker count meant that none of the existing amplifiers on the market would suffice. Historically, aftermarket amplifiers have been one, two, or four channels. The reason that six-channel amplifiers came to fruition is the increased demand for more channels from aftermarket amplifiers. You may be wondering why I’m bringing up speaker count in an article focused on the best 6 channel car amplifiers. In addition to getting louder and clearer sound, additional speakers are also a great marketing tool for the automobile manufacturer. As cars have become more electronically advanced, so have the stereos and, more importantly, the speaker count. In-car entertainment systems, specifically the audio segment, have become increasingly more sophisticated and complex over the years.
