Screws or staples should be placed approximately every 4" (10cm). For deeper bass it will require more airspace, thus a larger box. what would be the best amp for either of these setups? We recommend Titebond or Elmer's Wood Glue. The woofer can be mounted on the same side as the port or the back side of the enclosure can be slanted to fit up against your back seat.. On the cut sheets we provide, change the dimensions to accommodate the woofer and the vent on the same side. This created distortion because it would not accurately reproduce the signal the speaker received. If you did the calculations by hand or with a simple computer program (any program that requires only Qts, Vas, and Fs for enclosure performance calculations is simple), you will definitely want to measure tuning frequency because the vent dimensions given by the calculations could be off enough to reduce the speaker's performance. Calculate and subtract driver, brace and port (if ported) displacement from enclosure volume. This sealed single 12" enclosure is specifically built under Kicker's recommend airspace and will delver top end sound quality to bring every bass note to life!
