No. 1: Always try to have the speakers aimed at the listener. Never install speakers in a manner that would direct sound toward the floor of the car. The only exception to not aiming a speaker would be the rear deck (package shelf behind rear seat). The natural curve of the rear window, combined with the wide-dispersion tendency of bass sounds, allows woofers to perform exceptionally well in this location. This is not true for high-frequency sounds which will be absorbed by the roof liner long before they reach your ears. No. 2: High and mid-frequency sounds are very directional (the higher the frequency, the more directional it is). This simply means that a tweeter or mid-range speaker pointing toward the floor (or roof) will only be clearly heard in the direction at which it is pointed. For this reason, it is critical that tweeters and mid-range speakers always be installed so they aim in toward the passenger area and as high in the car as possible (on top of dash or high up in door panels). Never install tweeters low in the car. No. 3: Select solid mounting panels! Always make certain the selected panel is solid and securely attached to the car. Clipped-in plastic or fire panels make poor mounting surfaces and tend to vibrate when used. This is far more critical when installing large power producing woofers. Mount your speakers securely! If the speaker has four mounting holes, use all of them. No. 4: Woofers need “breathing” room! For a speaker to perform efficiently, it must move large amounts of air. If you restrict this airflow (try to fit a large speaker in a small space or if you undercut the recommended mounting hole size), you won’t have an efficient speaker. Conversely, the enclosure you mount them in should be somewhat sealed. In other words, if you mount speakers in door panels, don’t cut any extra holes in the door. No. 5: Tweeters can go in places other speakers can’t. They don’t need “breathing” room or reinforced mounting panels. All they require is directional placement. (See tip No. 2.) No. 6: Never let any part of the speaker (except the mounting flange) touch any part of the car. You’ll be amazed what noises a speaker (and your car) can produce when one touches the other. No. 7: Don’t skimp on the quality of the speaker wiring. All Audiovox speakers include w...
