installing music in your car, there are a couple
of things that you should know or consider before
actually going through with the whole deal.
Too Much Outside Noise.
Often we realize how noisy it is outside our car
after putting in a sound system in the car. And
also we realize how noisy our own cars can get with
the additional four 10" subs in the trunk.
It is almost impossible to get rid of all the noise
that your car can generate, however, there are some
solutions that can help ease the problem. The first
thing to do is to try and figure out where exactly
the noise is coming from. The license plate frame
is usually one of the first things to check when
a rattling noise is heard. If you can press this
down and the rattling is reduced then you have solved
one problem. Another place if not the most disturbing
place that noise can emanate from is the trunk.
One of the more common methods to reduce noise coming
from you trunk is to reduce the resonance of the
metal in your trunk. This can be accomplished by
using specially designed materials such as Dynamat
lined on the inside of your trunk. This only need
be done on the top underside part of the trunk itself.
Make sure to get in-between the metal braces on
the top of the trunk when applying the dynamat.
It is best to fill these spaces first and then apply
the Dynamat over the remaining parts.
To ensure that the Dynamat stays in position after
applying, use a heat gun and let it stay on each
piece for about 1 minute. Make sure too much heat
is not applied since this can affect the paint job
on the exterior part of the trunk. However, all
the Dynamat in the world can't help your noise problems
if the Dynamat is placed in the wrong places. There
are cheaper alternatives to Dynamat.
What you need to consider when trying to reduce
trunk noise is to make sure you target the main
areas. Fill in all the spaces between the metal
braces on the top underside of the trunk. Fused
fiberglass on the underside of the trunk is also
an alternative however, the finish is not as pretty
as one would like it to be. Another common problem
is that air tends to leak out of the trunk through
the trunk seal. If you lay towels along the trunk
seal and close it and the noise stops then you need
to get a new trunk seal.
Be Aware Of Where You Put Your Amplifier.
As you would have probably read on the Do's and
Dont's table, one of the more important things to
consider when finding a place to install your amp
is proper ventilation. One other thing to consider
that does not necessarily affect the amp's performance
but instead may become a nuisance later on. Many
experts in the car audio installation business suggest
that a good place to put you amp is on the side
panel in your trunk. Even though this is a good
place,it may come to your surprise sometime later
on when you have to change your brake light that
your amp rack went all the way to the end of the
side panel and is now jamming on the back piece
of your brake light. This makes it very tedious
to unscrew your amp rack every time you have to
change that light. So be aware of how close to the
brake light panel you install your amp rack.
Don't Blow Out All Your Fuses / Keep Live Wires
One of the many problems that people encounter when
doing their own installs is blowing the car radio
fuse. This may happen especially when disconnecting
your head set. Loose (open end) live wires dangling
around is not the idea situation you want to be
in. You may realize the live wire in some factory
instals by the color - it is RED.
However,if all the wires connected to your deck
are the same color then you can look for the polarity
markings on the wire itself. The live wire is the
one marked positive (+). When you get hold of this
wire, disconnect it first and tape the open end
with electrical tape until you are ready to connect
back up the head unit. If this still fails and you
are not sure about the wire's polarity then the
safest thing to ensure that you do not blow a fuse
or damage the head unit or any other devices in
your car is to break the circuit running from you
battery. This is done by removing the fuse from
the fuse box. In most cars, this is located on the
drivers side under the dash and on the side panel.It
is mapped with the name of the device relating to
the fuse position in the box. Look for the name
marked 'radio'. Pull out the corresponding fuse
in the fuse box. You are now ready to remove the
head unit.It should always be taken as a precautionary
measure to tape the open ends of all wires when
installing electrical devices in your car. 4)
Most of us have daily driven rides. We want to have
the baddest, loudest music system in our cars but,
there are prices to pay (and I am not talking actual
dollars). Lets talk about trunk space. According
to the type of speakers you use, the box to
them in increases proportionately with the speaker
size. This could tend to take up more trunk space
than wanted (if not the whole trunk). If you are
a regular at Maracas, then you can obviously see
some inconvenience in trying to find cooler space
when the time arrives. This is always an issue to
consider. Decide on which alternative you are going
to take before making that final purchase.
