It can be confusing to install multiple subwoofers in a motorcar, largely on account of there's some examination as to if you should manipulate unmarried or seperate competency wires and unmarried or seperate grounding points. On the contrary, the dare of the donkeywork can right be bill the rewards, in that multiple subwoofers deliver a sound punch conforming no other vehivle audio transaction can.
Instructions
1.5. Use RCA cables to send a music signal from your car stereo to your subwoofers. Your stereo or CD player should have auxiliary RCA cable outlets that you can use to connect it directly to your subwoofers. Link the two, turn on your subwoofers and play some music.
2. Use a regular distribution block to split the power wire into its component parts, if you elect to use a single wire. (You don't need one if you're using a separate power wire for each subwoofer.) Use a fused distribution block if your subwoofers don't come standard with fuse protection. The distribution block allows you to input a single power source and output it to multiple applications (your subwoofers).
3. Connect each power wire, or the single power wire's distributions, from the low-level output of your stereo or CD player to the low-level input of each subwoofer. To do this, you'll have to unscrew and remove your stereo, since the low-level output is located on the back of the unit.
4. Run a grounding wire from each subwoofer to a metal grounding point that is at least 12 inches away from the battery that will be used to power the subwoofers. If you're using a distribution block, it can double as a single grounding point for all grounding wires. If not, it's better to use a different grounding point for each different wire.
Bias additional speaker wire, either copper or silver. A useful regulation of thumb is to paired the proportions of wire you'd benefit to install a unmarried subwoofer for every further subwoofer you're going to manipulate. If you account a unmarried bent wire or multiple wires is up to you, though many experts asseverate that a unmarried wire makes the office easier and less confusing, by reason of you can always carry track of where it leads.
