ENCLOSURES All enclosures include port and subwoofer displacement. All ports are circle aero ports unless otherwise stated. Ported Enclosures: A ported enclosure is generally larger than a sealed enclosure Sealed Enclosures: A sealed enclosure will be the smallest enclosure you can build. It will have a tight low frequency response, but not as low as a ported enclosure.

ENCLOSURE CONSTRUCTION All enclosures should be constructed from 18mm (/4”) Medium Density Fibre board. Enclosures should be glued and screwed, because MDF is porous. FUSION recommends sealing the internal sides with a polyurethane sealer prior to installation. To accurately cut the subwoofer hole use the unique FUSION ruler guide included inside the FUSION Subwoofer packaging. ENCLOSURE PLACEMENT An important factor is to place the subwoofer enclosure as far back in the vehicle as possible

SERIES AND PARALLEL SUBWOOFER WIRING FOR DUAL VOICE COIL SUBS Parallel Voice Coil Wiring (1 Ohm operation) To wire a DVC subwoofer in parallel (to get 1 Ohm), use two short pieces of speaker wire and link the positive from one coil to the positive of the second coil, and do the same for the negative as shown in fig 1. Then wire the amplifier to opposite sides of the subwoofer in order to equalise any connection resistance. - Fig.1 1 Ohm operation Series Voice Coil Wiring (4 Ohm operation) To

TROUBLE SHOOTING No sound from your subwoofer: Check amplifier and wiring connections. Distorted sound: Check the connections from amplifier, processor or head unit. Subwoofer makes unusual noise in sealed enclosure: The enclosure may have leaks causing a lack of back pressure. Remove the subwoofer and ensure the enclosure is completely sealed, use sealer and polyurethane to do this. Ported enclosure makes an unusual noise: Possibly due to incorrect port used. The correct term is chuffing, an
