Pre-fabricated sub enclosures

While ready-made subs have many advantages, you will have a greater choice of subs if you choose a component subwoofer and an appropriate enclosure. You choose the subwoofer or subwoofers that suit your musical needs best, and then select the box size that will optimize their sonic properties. You will find that most component subwoofers do not come with any hardware. If the enclosure you purchase does not have hardware either, you might have to provide your own screws. Also, you might need speaker wires and hardware to connect the speaker to the terminal cup in the box. Finally, find some brackets or straps to hold the enclosure in your vehicle.
