How to make your Z sound better
By James Patterson,
There have been a lot of questions posed on how to get "good" sound in a
Z. Personally I prefer the header, 2.5"exhaust and flowmaster route but
that is just what I call "music to my ears". On the other hand I have a
friend who is a professional car stereo sales/installer and a national
IASCA judge (the huge sound competitions). He is also a Z enthusist. He
has done about all you can do to make his Z fast (custom threaded and
shortend struts, port and polished, balanced and blueprinted 2.8 hi-comp
with Mikuni side drafts, headers, etc...) and have good sound.
( the car is 71Z)
These are some of the things he has done:
This all sounds like overkill to me... but if you want "good" sound...
This is what someone who was looking for the best possible sound in their
Z did. He also noted that the Z with it's small passenger compartment and
highback seats makes a terrible sound platform but it sure is a hell of
alota fun 8).
- Sound deadening all interior surfaces using a combination of Dynamat and
carpet jute. This is a must, the Z is a very noise intrusive car.
- For front speaker placement, tweaters mounted flush in the metal plate
at the top of the dash give fairly good imagining. Since he has power
windows he made small enclosures to hold 2 3" mid-range drivers per door
mounted at the lower forward edge. (This has been a slight problem
because when you are sitting in the seat the knee tends to rest against
it. This is not uncomfortable nor does it place strain on the enclosure,
but it does muffle the speakers somewhat.
- For the rear compartment he has built a deck which raises the height
about 2". At the front of the deck are the system amplifiers. These are
sunk into the deck so there surfaces are flush with the deck. In the
spare wheel well he has heavily lined and insulated it to hold the 15"
bass driver. This fires directly up and is mounted below the deck with a
flush screen gaurd to protect it. He has lost the use of the spare to
say the least, but he has said that with some modifications and a
mini-spare a small (6 or 8") driver could be used. For the rear speakers
he built a small panel which fits below the rear hatch lip. This
necessates the removal of the platic panel and he has a set of mid-range
and base drivers firing towards the front. This still allows for full
use of the rear area with only a small loss of space due to the raised deck.
