If you are looking to power some speakers to bring your car audio experience to the next level, a great 4 channel amplifier is likely your most cost-efficient option. 4 Channel amps are quite versatile since they can be wired in various ways to produce the best sounds possible. However, finding the perfect 4 channel amp for your vehicle is not always easy. We made this guide to simplify the process for you so that you can maximize your car’s audio quality without breaking the bank.
Shopping for a 4 Channel Amp
Here are some questions to ask yourself:
- Is the size right? Whether you plan on placing your amp in the trunk, under a front seat, or anywhere else in your vehicle, you will want to ensure it will be a great fit. Thus, measuring your available space ahead of time can save you some complications down the line. Thankfully, amps have been getting smaller and smaller while providing excellent power.
- What will your amp be powering? Even powerful, well-made amps can be ruined immediately if you are not careful. Thus, you should make sure your new amp can handle the ohm load that it will be connected to. Additionally, it is equally important to ensure your amp has all available crossovers for the applications you plan on implementing.
- Is the amp built to last? If you are purchasing a 4 channel amp for your car audio setup, it is likely to take some abuse from your vehicle’s normal vibrations. It can also be kicked if placed under a seat, or overheat if pushed too hard. Thus, finding an amp that is durably constructed (aluminum casings are ideal in this regard) and great at dissipating heat can help ensure that your amp lasts a long time.
