How to Install an Old Infinity Subwoofer
- 1). Check the label on the rear of the speaker magnet. Check for its impedance, measured in ohms, as well as the number of voice coils on the speaker, which can be identified as the number of paired audio terminals. Your amplifier should be rated at the same impedance level as the speaker.
- 2). Connect one end of an appropriate length of speaker wire to the positive terminal on the speaker, and the other end of this wire to the positive terminal on the amplifier.
- 3). Connect one end of the other wire to the negative terminal on the speaker, and the other end to the negative terminal on the amplifier. If your speaker has more than one voice coil, connect a jumper length of speaker wire to sync both coils together.
- 4). Mount the subwoofer into an enclosure and place its protective grill over the speaker's cone.
