The placement of the speakers will vary from vehicle to vehicle. Most vehicles have factory
cut-outs on the rear window deck behind the rear seat, in the front doors, or front kick panels.
Before permanently installing the RS400 speakers in your car, connect the wires to the
speakers according to your audio systems installation manual in the approximate location
you will install them. If you are satisfied with the location, proceed with the permanent
installation.
Before you install the RS400 speakers, you must make sure
you have enough depth/space behind the mounting surface.
You do not want the back of the speaker magnet to touch any
part of your vehicle or interfere with the operation or function of
any component in your vehicle. (i.e. windows or trunk lid)
What if there is no sound?
1. Your stereo may have a blown fuse. Replace fuse with the same amperage and style.
2. You may have improper wiring. Refer to the wiring guide that came with your stereo/amplifier. Check
all wires for a secure connection.
What if the sound volume is low?
Your stereo may not have enough power; you may have to install an amplifier to drive the speakers.
Why do I have a whining noise coming from the speakers?
You may have poor filtering of your alternator. If that is the case you may need to add an alternator filter
to the power lead.
Why do I have odd sounding noises coming from the speakers?
You may have corroded battery terminals and/or a weak battery. If the terminals on the battery are
corroded, clean them; then check the sound. If the sound system is still making noises, check battery
strength. If it is low, recharge or replace the battery.
Why does the speaker have sound coming from one channel only?
First make sure the balance control is set correctly. If the balance is set correctly, your stereo may be
defective or the speaker may be defective. To troubleshoot this problem you MUST change both
positive and negative leads of each channel with the positive and negative leads of the opposite
channel. If the same speaker has no sound, then the speaker is no good. If the opposite speaker has
no sound your stereo may be defective.
You should only mount your speakers in factory precut holes. We DO NOT
recommend that you cut holes for mounting the speakers. If there are no
factory precut holes consider having the speakers professionally installed.
1. Connect speaker wires.
2. Slip the spring nut(s) (provided)
into place and align the holes.
3. Place the speaker grill on the
speaker, lining up the hole for
the screws .
4. Screw the speaker and grill into
place with screws (provided).
The RS400 may be installed in a speaker
enclosure. Use the supplied template to
check if the holes in the enclosure matches
the speaker.
All auto audio components must be securely mounted. Driving styles and
road conditions such as sudden stops, sharp curves, and bumpy roads
may cause unsecured items to move about the vehicle, causing physical
injuries to vehicle occupants and/or vehicle damage.
When connecting the speaker wires to your speakers in a new installation, you should follow
the wiring instructions from your audio system’s manufacturer. For most systems the positive
wire attaches to the positive speaker terminal and the negative wire attaches to the negative
terminal.
Use a knife or wire strippers to strip
the insulation off of the last half inch
of the individual wires. Twist the
strands of wire together.
Press on terminal until holes line up. Insert the wires as
shown. Maintain proper polarity by attaching the Positive
Wire(+) to Positive Terminal(+). And attaching the Negative
Wire(-) to Negative Terminal(-)
