One misconception about car audio is that
bigger is always better. To me quality is just as
important as quantity. When choosing the
components for my audio system I decided to go
for an overall clear sound with upgraded speakers
for low, mid, and high frequencies. Some people
may want a lot more bass so they will add a lot of
subwoofers, some may want a lot of high pitched
sound so they will add tweeters. I basically
wanted to upgrade all of my speakers to ones of
much higher quality that will be louder than the
stock audio system but that will also deliver
extremely high quality sound.
Lets Start With Some General Terminology:
RMS (root mean squared)- this basically the
constant power that the speaker can handle at
a steady rate.
Max wattage- this is the maximum wattage a
speaker can handle during very short bursts.
Ohm- this is the impedance or how hard the
amp has to work to push the speaker.
The vehicle I will be
working on is a 2004 Nissan
Titan. It is crew cab and has a
basic factory audio system.
Lets Start With The Brain
I chose the Pioneer
my stereo deck. It
features a DVD
player, a 5.8” touch
screen and lots of
inputs and all of the
outputs I need. It also
fit my budget.
Now on to the Speakers
I chose to go with two component speaker systems for my door
speakers. Each system includes 2 6.5in mid range speakers and 2
tweeters, for a total of 4 speakers per system. They also have 2
crossovers units. I chose the Kicker 08KS6502 component system
because they are a middle of the line component system that's not too
crazy and that fit my budget. They are rated for 75 watts rms power and
150 watts max power.
For my amp I chose the
Kicker 10ZX700.5. This is a 5
channel amplifier, meaning that it
has a channel for the subwoofers
and a channel for each door. It
outputs 70 watts rms at 4 ohms to
each door speakers and 420 watts
rms at 2 ohms to the subwoofers.
This is the perfect wattage for the
speakers and subwoofers I have
chosen. It will output slightly more
wattage than the subwoofers are
rated for but Kicker says that
everything is underrated and I can
always turn the amp down.
I chose two Kicker
Comp 10” subwoofers
for my subs. They
are an entry level sub
but are good for what
I need. They are rated
for 150 watts rms a
piece and 300 watts
max per sub.
The Subwoofer Box
I ordered a custom built box off the internet that fits perfectly up
under the rear seat of my truck. It has the adequate air space for the
subwoofers to function properly and it was almost cheaper to order it
than to build it.
I also ordered a 0 gauge wiring kit that
includes all of the wires and connectors I
will need for installation, as well as
adapters so I can install the door speakers
in the factory speaker location. I also got a
factory integration wiring harness for the
pioneer deck and a steering wheel control
Now on to Installation…
I got the Pioneer
deck in first, so it was
the first to go in the
truck. Installation was
very simple and all I
did was plug it in to
the factory wiring
harness and mount it
in the dash. I used a
dash kit to fit the
bigger screen in the
factory radio location.
Next Step: Installing the Subs
I wired the subs into the
corresponding terminals on the
inside of the box.
I then mounted the subwoofers in the box
I then put the subs and box under
the rear seat
I mounted the amp against the back wall of
the cab of the truck.
I ran the 0 gauge power wire from the amp,
through the firewall and to the battery. I grounded
the amp to one of the seat bolts.
I ran all of the RCA wires to the head unit and all of
the speakers wires to the corresponding speakers.
I used this wiring diagram so that I had a 2 ohm load for the
amp to the subs.
Installing the Door Speakers
First I removed the factory door speakers and ran the wires from
the crossover to the door speaker.
I then installed the adapters for the front door
Next I connected the wires to the speakers and
mounted the new speaker.
This is the basic wiring diagram for the
component speaker system
After installing the front door
speakers I installed the tweeters in
I repeated the install on the back doors
