Things You'll Need:
- Car subwoofer Speaker wire Speaker box Wire strippers (if applicable) RCA connections and cables (if applicable)
-
Step 1
Figure out the Ohm output of the unit, be it a cable box, receiver, DVD player or another device. All 8 Ohm units should be mated to 8 Ohm speakers, 4 Ohm to 4 Ohm, and so on and so forth. Your sound will be cleaner and the speaker much less likely to blow if this is done.
-
Step 2
Figure out the wattage of the unit, or how many watts it sends out to the speakers, both peak power and RMS, which is 70 per cent of its peak power. Sending 200 watts into a speaker designed to handle only one hundred, will greatly shorten the life of the speaker. Match these units as closely as possible.
-
Step 3
Place the speaker in a box that will enhance its performance, if it is not already boxed. If both wattage and Ohms match up, you can replace an existing house speaker of the same dimensions with a car audio speaker, as well. If using your own box, install a crossover that will only send the low signals to the woofer, providing a crisp, clean sound.
-
Step 4
Connect the speaker to the main unit via the speaker wire. If the unit uses RCA connections, it may be necessary to modify the hookups at the speaker or box. If implementing the traditional red and black clamp-down style connections, simply bare the speaker wire and hook negative to black and positive to red. Positive is normally the wire with a stripe on it.
