This page contains links to some of my stuff that I don't have
time to dedicate a better site to.
It is an accomplishment enough that I actually took the time
to scan some of these and upload them!
I just happened upon a photo book I put together in about
1998, the following links all lead to pictures that I scanned
from that photo album.
The first set of links pertain to my Civic mainly,
the last set of links reference car audio installation
work that I have done over the years (prior to 1998), so scroll
down if you don't care about my Civic.... Enjoy!
The evolution of my 1995 Honda
Civic - This scan shows three pictures of my car:
- The top picture represents the car as it was relatively
stock... as it was when I bought it in 1995.
- The middle picture shows my car after some mild
modification, I believe that I had the Neuspeed Springs
and Koni struts, but that was it suspension wise at that
point. The wheels on the car were Boyds, this was before
the "sport compact car" explosion, I thought it
would be unique to run a hot-rod-wheel like Boyds on a
modern car like mine. The car looked like this from '96
until '97.
- The lower picture shows my car pretty much as it is
today, the wheels are Enkei's, the paint is monochromed,
and the only thing really different today with my car is
that my current taillights have replaced the amber
section with clear, although the red remains the same so
the effect is subtle. Too many mods are on the car to
list here..
The first install I had in
my Civic - My first install in my Civic was done pretty
quickly, I wanted a nice install but had to focus on my
customers.
- Pretty basic, three JL Audio 10W6 10" subwoofers in
sealed enclosures on either side of the trunk, the rear
wall of the boxes molded in fiberglass.Water was used to
ensure proper enclosure volumes. The boxes were sanded
and painted with a blue fleck-stone finish. The subs have
3/4" thick plexiglas loading panels in front of
them, this technique (called compound loading) allows
them to reach higher output than a stand-alone sealed
enclosure.
- The amp rack is fan cooled, covered in blue plexiglas.
The amp rack is hinged in two places, the first section
hinges to display a plexiglas window covering exposed
Alpine V12 MRV-1000 amp internals, note the capacitor
bank - the V12 stickers were on there from the factory!
The second hinged section lifted to access the spare
tire. I was never really happy with the appearance of
this setup.
Construction of my
new Civic install - These shots show the rough progress of
construction of my current install.
- The top shot shows the enclosure relatively complete. I
can't find any shots earlier than this, unfortunately,
right now. The bottom of the box is molded out of
fiberglass. Two 4" PVC ports extend from the sides
of the enclosure. You can see that I made a spare tire
compartment out of fiberglass, as the enclosure would
occupy the factory spare tire well. I just have two
wooden panels suspended on the sides, which will
eventually hold my amps.
- The middle shot shows a close up of the plywood panel
that was being built to trim out the trunk and frame the
amps... You can see that they will completely hide the
ports so they will not be visible.
- the bottom shot shows another close up of this section
with further progress. The amp racks are trimmed with
grey marbled Formica, as are the homes for the two
inverted subs, and the spare tire well cover. At this
point I have the vinyl work for the side panels complete,
and am just finishing up trimming out the opening.
My new Civic install
complete - These shots are simple enough, three shots of my
completed trunk. The amp racks were surrounded by mirror. The amp
on the right is my larger 2 channel Alpine V12 that powers the
subs. The amp on the left is a smaller 4-channel V12, it is
currently bridged to power my component set up front. You can see
the completed marbled formica and vinyl work. The round cover
trims off my fabricated spare tire compartment.
The following are some of the installations I worked
on prior to 1998:
Floor-bandpass S-10 installation
- Highlights of this install include:
- Single-vented isobaric bandpass enclosure. The isobaric
clamshell style configuration was split open, with an
orange plexiglass cover displaying the two woofers. This
displayed chamber does nothing but isobarically couple
the two subwoofers. This bandpass did not perform well,
initially... The port exited on the far drivers side, and
the interior acoustics caused for cancellation and low
output which had to be addressed.
- Armrest amp rack. I fabricated an armrest to occupy space
vacated by the jack and tools. The amplifiers were
mounted under this armrest. This installation allows full
use of the rear seats, the low profile of this very thin
bandpass box allows them to fold down all the way, and
the armrest is a comfortable height. A floormat was made
of the same carpeting to cover the orange plexi window
for security purposes.
- Not pictured is the custom dash panel made of reverse
painted black marble on a panel made of orange plexi to
match the appearance of the isobaric chamber with its
black marble interior.
Stealth isobaric install in
Eclipse - Highlights of this install include:
- Top picture shows the completed install with carpeted
covers in place, security was an issue with this
hatchback owner.
- With the carpeted cover removed, the trunk is still
carpeted, but allows the display of the dual Eclipse
subs. This isobaric arrangement was done much like the
S-10 above, allowing for display of the isobaric chamber.
The same orange tinted plexiglas was used for this
install. An interesting note about this install was that
it was a standard ported isobaric box, one subwoofer was
inside the enclosure, the other basket was exposed to the
interior, as a standard ported isobaric setup would be.
The port opening was right next to the subwoofer's
basket.
- The bottom picture shows the rear seat folded down, and
its cover flipped up to expose two generations of
Rockford Fosgate amps.
Eight JL 10W0 subwoofers in a
Firebird - Highlights of this install include:
- Eight 10W0 subwoofers. These subwoofers are arranged in
two banks of four, also an isobaric arrangement, allowing
eight subs to work properly in the airspace normally
needed by only two of these. The bottom four subwoofers
are viewable via a relatively thin (1/4") plexiglas
panel, as this isobaric chamber will always be of ambiant
pressure.
- Two channel 1000 watt Soundstream Reference 1000 amp.
This amplifier powers the entire stereo, subwoofers and
JL Audio components up front. A set of relays was used to
manipulate this amp's "auto high current" mode.
When in Sound Quality mode, the subwoofers were wired in
a series-parallel arrangement allowing the amp to run
high power mode, with the speaker power handling factored
in, the front speakers receive about 100 watts with the
subwoofers receiving 400 watts. When in SPL mode, the
subwoofers wiring configuration is modified by the
relays, and they receive 1000 watts of power.
- The passive crossover network (the capacitors and coils)
was hand built to allow a single 2 channel amp to power
an entire full-range system. High frequencies only go to
the component set, while only the low frequencies go to
the subwoofers.
- The amp rack appears to float, and is neon lit from below
to make the edges of the plexiglas glow blue with no
apparent light source. The amp rack is fan cooled with
narrow squirrel cage fans on either side, the hot air
exiting through the "JL" logo cutout on the
plexiglas cover at the middle of the amp.
Marble painted finishes I
have done - I have found that very often a more custom, more
professional appearance can be had by properly performing
"bodywork" to the completed enclosures that I have
done, prepping them for paintwork rather than cover them in vinyl
or carpeting. Most often, I prefer to prep and paint my
enclosures with an interesting finish rather than the traditional
vinyl or carpet. These pictures show a marble finishing technique
I do.
- The red box was the original install in the Firebird
above, before upgrading to eight subs. This was a ported
enclosure that fired the subs inches away from the front
wall of the hatch well. I painted the port black, the box
red, and then marblized the enclosure. Even though red
marble doesn't exist in reality, I think that this finish
was done well enough that it pulled it off. The owner of
the Firebird was a big fan of red.
- The green box was actually installed in an Estate wagon
owned by a friend of mine. It occupied space formerly
owned by a pair of spare seats which flipped up in the
hatch area of the wagon. This enclosure is a dual-vented
isobaric bandpass box, mounted to the box are a pair of
small amps (legendary Alpine 3522 and a Pioneer amp) and
a Coustic XM-3 crossover. I couldnt bear the thought of
sealing the subwoofers in the enclosure, so I mounted a
small scrap piece of plexiglass at an interesting angle
on the top, allowing the viewing of a pair of MTX Road
Thunder II subswoofers. You can see the two square ports
on the right hand picture.
