speakers.
10.Installation is now complete, please see “Configuration of speakers with power
source” to configure your speakers, and prepare them for use.
If constructing a rear “parcel shelf” or modifying your existing one…
If modifying your existing parcel shelf, only follow steps 2, 3, 6 and 7.
1. - Use your existing shelf as a template and draw round it using a pen or pencil onto
a sheet of 18 mm mdf.
- Cut round the marked area (using a jigsaw or similar) to give a basic outline of the
old parcel shelf.
- Place the new shelf into the rear of the car; you may need to make modifications
to it such as cutting a small square from the corners and inserting screws to allow
the shelf to “click in” to the vehicle’s parcel shelf hinge. Try to attach the old elastic
cord to the new shelf to allow it to lift up when the boot is opened.
2. Decide where best to mount the speakers and use the template provided (or grille
surround) to mark out the holes that need to be cut for the speakers.
3. Cut out the holes using a jigsaw. Never go outside of the lines you have marked.
4. Cover the shelf with acoustic carpet material; staple it neatly along one side
underneath the shelf and stretch it over the front of the shelf to the other side and
staple it down underneath. Keep stretching the material when stapling to allow it to
lay flat. Use spray-on glue to help the carpet stick to the shelf. If wanting to mount
the speakers underneath the shelf and not present them visibly on the shelf, it is a
good idea to staple extra blocks of material over the holes before carpeting so that
the material does not “sag down” over them.
5. If wanting to present your Competition Pro speakers visibly on the shelf, cut away
the carpet over the holes neatly, place your speakers into the holes (easier to do
when shelf is installed in vehicle), and mark onto the material where the four
mounting screws or bolts will go. Remove the speakers and either drill a pilot hole if
mounting with screws, or drill a hole large enough for the bolts if mounting this way.
If wanting to mount your speakers underneath the shelf, (so they are not visible
from the top), turn the shelf over and place the speakers where they are to be
mounted.
6. Attach the speakers to the shelf with either self tapping screws or bolts provided.
7. Proceed to point 5 of the “Installation Instructions” (page 7).
1. Turn the gain knob on the amplifier and/or source unit all the way down
2. Play a CD or similar of music or audio that will be typically played
3. If using an amplifier, turn the gain control on the source unit to around 70 – 80% of
it’s maximum. If only using a source unit, increase the gain until just before
distortion is heard. Never increase the gain above this level.
4. Slowly increase the gain knob on the amplifier until you can hear distortion
5. Turn the gain knob on the amplifier to just before this distortion occurs
6. Test the system and make any equalisation changes on the source unit or the
amplifier according to taste
7. If any equalisation changes are made, repeat stages 1 to 7 until satisfied
8. Never exceed the source unit gain that you used to calibrate the system
Remember: It is possible for the amplifier’s gain knob to be at only a quarter of its
maximum, but the amplifier is actually outputting to its full potential. This could be
because the source unit is supplying slightly more power than normally expected.
The Competition Pro range of car audio is built for very high power handling. Listening to
music at such high powers is potentially capable of causing physical side effects such as
nausea or even permanent side effects such as hearing loss. It is therefore absolutely
essential that conservatism and a high sense of judgement is observed when in operation.
TheLoudest.com accepts no liability for hearing disorders, nausea or other side effects
caused by this equipment.
General Safety
Playing loud music in a vehicle can hinder your sense of what is going on around you on the
road, including your ability to hear your own, and other vehicles. We recommend listening
at low or moderate levels while driving. TheLoudest.com accepts no liability for injury,
property damage or otherwise resulting from the use or misuse of this equipment.
Do not use any chemicals when cleaning this equipment. Please use a clean dry cloth.
Do not install this unit outside the car, or anywhere where it could become damp or humid,
or where it can become exposed to the sun. It should be installed in a dry and ventilated
area inside the car.
Never connect or disconnect speakers when the amplifier is on; this can permanently
damage the speakers. Always do this when it is off.
None of the parts are serviceable by the user. In the case of the unit needing repair or
maintenance, please take it to a qualified professional.
Possible Cause(s) Solution
Distorted output Source unit/amplifier gain
set too high
Source unit is not capable of
good audio reproduction
Speaker(s) blown
Speakers being run from 2
ohm amplifier
Re-calibrate speakers
Replace/upgrade source unit
Disconnect speakers one at a time to
pinpoint defective speaker
Don’t bridge channels/seek advice.
Speakers need to be run at 4 ohms.
Bass is weak Speakers wired out of phase
Eq settings are reducing
bass power
Check the + and – connections all
match
Return all eq settings on amplifier and
source unit to default
