| My favorite
color of the '89 model Speedster is now silver. This car looked so "at
home" in my driveway while I worked on it, that I really feel convinced that I will
someday have to own one. Definitely a silver one. The dark blue (actually
"Marine Blue") interior and dark blue top look very good with the silver
exterior. What a neat car! The
current owner wanted to "undo" what the previous owner had installed.
There were some good quality components, Rockford Fosgate and Eclipse, but the
installation was really bad. For the subs, they'd merely cut 2 rough holes in the
rear "shelf", dropped in some 10" subs, without really trying to enclose
the underside of the panel. One door speaker had apparently been damaged during
installation (oops!), the changer was sliding around on a hastily constructed panel in the
trunk along with two Punch amplifiers. The crossover for the "highs"
amplifier wasn't setup correctly, and the whole system, about $2k in components, sounded
very poor. I probably spent 1.5 hours just "un-doing" some of their
work. My customer wanted something that looked original with good sound. We
(Jon Birch and I) installed JL Audio XR 525 CX 2-ways in the doors, 4" XR's in
the rear (both sets come with separate crossovers), a Sony XM754HX amp under the passenger
seat, Stinger 1/2 Farad Capacitor under the driver's seat, Kenwood KDC 8009 revolving
"Mask" face CD indash player, 10 disc Kenwood CD changer in trunk, and a custom
enclosure (14.5 hours worth) with two JL Audio 8W6 8" subwoofers. The end
result looked very "factory" original, and it sounds phenomenal. Great
sound, even with the top down! |

For the subwoofer enclosure, I started
with the rear "shelf" and built it up with layers of 1/2" MDF so that I
could recess the speakers under steel mesh grilles, with a panel that fits into the upper
recess (upper grille is removed for this picture). I used factory Sliverknit carpet,
and the grille is covered in dark blue grille cloth |
 This is what the underside of the
enclosure looked like. I actually built one complete enclosure for each sub, lined
with Road Kill Pro mat, and stuffed with Acousta-Stuf. I figured the exact
airspace/volume required using a woofer tester to find actual driver parameters, &
Bass Box Pro. |
This is the enclosure, with
the flush grille piece in place, and the speakers are still protected by steel mesh
grilles. |
