SPEAKER LOCATION AND MOUNTING TIPS
THE FIRST STEP IS THOROUGH PLANNING BEFORE THE
INSTALLATION BEGINS.
THE SPEAKER SCREW HOLE CONFIGURATION WILL WORK WITH
MOST DOMESTIC AND FOREIGN VEHICLES.
FOLLOW THESE INSTRUCTIONS CAREFULLY TO ENSURE PROPER
IMAGING AND MAXXIMUM PERFORMANCE.
Factory Speaker Replacement Location and Installation
1. Before you alter the vehicles interior materials, be sure there is
adequate room and clearance for the speaker depth to clear the
windows and other moving parts. (See speaker measurement page).
2. If you are using the speaker wires provided in this kit, be sure
to route wires through the factory door grommet as shown in the
speaker mounting diagram.
3. After securing the speaker and checking clearances, connect
the red/black speaker audio wires to the correct speaker + and spade terminals.
Custom Speaker Location and Installation
1. Follow steps 1-5 above.
2. Use the speaker mounting diagrams and speaker hole cut-out
dimensions on the following pages.
3. Always mount the left and right side speakers on the same plane.
This means that each speaker should be the same height from
the floor and same distance from the firewall. Do not mount one
speaker higher, lower, further forward or further behind the other.
3. It is always best to keep the tweeter (component speakers) as close
to the mid range driver as possible. Typically with-in 12”.
The tweeters tend to sound best when aimed towards the rear center
of the vehicle.
