Car Audio Amplifier Basics:
Amplifiers do exactly what their name implys, it ampilfies the signal from the signal source such as a head unit or receiver. A car audio amplifier provides a clean signal to feed your speakers or subwoofers. This can be crucial at higher volumes to ensire proper sound quality.
***PLEASE NOTE*** All information on this site is for educational and informational processes. Any guidelines, tips or recommendations are considered general knowledge and we strongly encourage you to consult with a professional before installing, adjusting, or altering a car audio system.
For your subwoofers, use a MONO block or class D amp so their signal is on a single channel thus is in unison. Some builds use mutiple amps to increase power and/or change impedence. The amps can be independent or strapped together. Most car audio amplifiers include a birth sheet upon purchase with the results of the amplifier being tested on a dyno. Remember over powering subwoofers can lead to equipment malfunction and failure.
Car Audio Amplifier installation ugrade requirements:
Another key element to upgrading your amplifier is proper amperage for your amplifier to draw from. Install a volt meter to moniter your voltage with the system off, on and playing. You will notice certain elements such as high kick notes will cause a strong draw as well as loss of amperage over time. Be sure to upgrade your electrical properly including proper amperage from your battery and high output alternator and proper amount of power and grounds wire runs.
Find the right balance between quality and budget. Buying products that are cheap and not quality could result in replacement and expenses in the future. Best Practice is to start right and not have to do anything twice.
