SYSTEM PLANNING

SYSTEM PLANNING

Before wiring up an audio system that may not achieve the sound quality you want, be sure to choose a system concept that fits your listening requirements. Basic systems, a receiver with internal 4x20 watts and 4 coax speakers, are adequate for many listeners. But, when you want to really “feel” the music, you will need some kind of subwoofer amplifier/speaker combination. Although many people might jump into an “add-on” amplifier to power to rear coaxial speakers, a better choice is usually a subwoofer amp/speaker system that supplements the existing 4 speaker system as shown in the adjacent drawing. Such a system provides a surprising improvement in sound quality due to the usually dramatic increase in bass response.

The next dramatic step up in performance is with a “multi- channel” system that offers more dynamic range in the mids and highs due to higher power plus more bass response due to multiple woofers and/or more power. But, with such a system, the stereo image and overall listening experience usually becomes much more life-like due to better tonal quality midrange/tweeter speakers and usually better placement.

To build such a system though, complexity goes up due to the addition of passive or active crossovers which take time to install and may inject noise into the system due to potential noise signal pick up. The results though of such a system can be dramatically pleasing.

INSTALLATION TOOLS

For most installations, simple hand tools are adequate to install an aftermarket amplifier. Depending upon the mounting locations used, you will need power tools for drilling and cutting plastics and metal. A good starting list is summarized below:

Tape measure and ruler

Marking pen and starting punch

Phillips and flat blade screwdrivers (small and medium sizes) Nylon wire bundle ties

Pliers: standard vice-grip and needle nose styles Light-duty trim pry-bar for removing door trim

Cutting shears or nibbling tool for cutting thin and medium gauger metal

Wire cutters, wire strippers, electrical tape, crimping pliers and appropriate crimp-on terminals

Power drill with appropriate sized drill bits
