It isfor this reason that you must be able to calculate the space in which you have available in order to achieve the proper air volume required. Calculating External Vblume 1)To calculate box volume, measure the outside Width x Height x Depth of the enclosure. Example 12" x 14" x 9" = 1512 cubic inches. 2) Next you must convert cubic inches into cubicfeet.To do this, you must divide the cubic inch total by 1728. Example 1512 cu in ^1728= .875 Cubicfeet. Calculating Internal Vblume 1)To c

Depth 9" -1.5" = 7.5" 3) Multiply the new totals (HxWx D) Example: 10.5" x 12.5" x 7.5" = 984.375 cubic inches. 4) Next you must convert cubic inches into cubicfeet.To do this, you must divide the cubic inch total by 1728. Example 984.375^ 1728= .5696 cubicfeet.

We have designed the ARC Audio subwoofer to perform well when used in both sealed and ported enclosures. The acoustics of your vehicle also influence bass response. The small interior size of most cars and trucks boosts low frequencies dramatically. You will need to use a smaller enclosure then normal to achieve a flat bass response. As a rule, below 50Hz (depending on cabin size), bass response increases at about 12dB per octave as the frequency decreases. This "Cabin Gain" adds significant bas

This is the MAX power rating. Continued use of this woofer at greater then the RMS power rating will result a damaged (burnt) voice coil. This damage is considered abuse and is NOT covered under the warranty. Small Amp Myth Under powering a woofer is fine. This woofer will suffer no damage from a 100 watt amp if it is correctly tuned. However, even a small amp that is being over driven (clipped) can destroy a sub. Use your power wisely. Clipping can be heard as a dull thud or a popping sound. If

What does this mean? Your amp does not make power, it takes power from your battery and converts it into a different form. The subwoofer is just another kind of converter. It changes AC voltage from the amp into changes in air pressure (that's sound is) and HEAT. The more energy being converted the more heat. A speaker can not reproduce DC voltage (produced when an amp clips) but this energy must go somewhere. It is all converted into heat. This is why clipping is so dangerous to a speaker. A gr

The size and vent tuning frequency, if you're using a ported box, determine the low-frequency extension and output of the subwoofer.

Sound deaden, it will sound better and hit harder. Building an Enclosure It is recommended that you use 3/4" MDF (Medium Density Fiberboard) to build an enclosure. Glue all your joints with yellow glue and secure then with screws or nails. Make sure the enclosure will fit and that you have adequate room to get it in and out of the vehicle. Calculating Enclosure Volume It is difficult to give exact box dimensions that are universal for all cars and trucks. It is for this reason that you must be a
