If you selected door locations, you might need to punch a small hole in the door edge (near the door hinges) to route the wires into the door. Leave enough slack wire to open the door all the way.

5.Securely connect the positive (+) and negative (–) stripped speaker wire ends to the corresponding speaker terminals.

(illus - show the speaker wires properly wrapped around the speaker’s ter- minals.)

Cautions:

Improper phasing can cause poor bass response. To ensure proper phasing, you need to match your autosound sys- tem’s positive (+) and negative

(–)speaker wires to the corre- sponding positive (+) and nega- tive (–) speaker terminals.

Do not connect any of your speaker terminals to chassis ground. Use all four autosound wires to connect your speakers to your vehicle’s autosound sys- tem.

If you have a two-speaker sys- tem:

6.Remove the grille from each speaker’s mounting bracket to expose the mounting holes.

7.Place the mounting bracket on the speaker.
