Car Stereo Amplifier 4-Channel

A 4-Channel Car Stereo Amplifier is the traditional way to upgrade a car stereo system. Today’s high-performing Class-D amplifiers are stable to extremely low loads, and many cases build to run this way. Some 4-Channel Car Stereo Amplifiers can be run not only in 4-channel mode but also as a 2, 3, 5, and even 6-channel using mixed mono configuration. Depending on your application, some of the features to look for on a 4-Channel Car Stereo Amplifier are line-level input, high and low pass crossover, subsonic filter (if adjustable even better), and pass-through for future expansion! Some people say that DSP is a must! I don’t think it is a deal-breaker, and while a nice feature to have, especially if controlled via Bluetooth unless you know what you are doing, tunning a DSP amplifier may be more than you are bargaining. Consider sticking to what works and 4-Channel Car Stereo Amplifier with good reviews from the DIY car audio market segment.
