just got this one done, its the first SQ install i have done in a E36. this one was a yellow 97 m3 coupe.
goals:
1. very good sound quality
2. clean and stealthy
3. reuse some existing gear provided by the customer
lets get started:
the signal starts with alpine 7898 hiding face headunit that was already installed in the vehicle:
front stage is a pair of Seas Lotus reference 6.5" two way components, the tweeters were installed into the A pillar. this turned out to be a bigger challenge than normal due to the fact htat there is zero room behindt he factory A pillar cover, and the seas tweeter is quite large...so it had to be moled out a bit more than normal:
here are two quick build up pics:
the molding:
and finished vinyling (lots of pulling and cursing lol)
the midbass also presented a challenge, since the stock size houses a 5.25, and the lotus is a rather large 6.5", after some deliberating, what i came up with was to mold a ring baffle into the stock kick panels, cut open the back area some more, and put plenty of clay and dampening into it, so when i install the spekaer and the kick against hte back metal, it forms a decent seal the midbass utilizes hte stock cavity behind the metal.
but here is hwat they look like installed in the car, very stealthy and unobtrusive, the kicks are texture coated:
some build up pics of the kicks:
here you see the ring baffles molded into the stock kick panel:
after texture coating:
the back built up wtih modeling clay and dampening:
passenger side speaker installed:
driver side:
bad pics but the cavity oipened up a bit more and fbuilt up a bit too with clay and dampening:
the front as a whole:
and the USB cable for the zapco processor comes out of hte glovebox for tuning:
moving on to the trunk, a very simple design, here is what it looks like all covered up:
pop off the panels and an image dynamics IDQ10 fires backward, and a macintosh MCC404M 4 channel amp sits in the floor, both are flushed mounted in yellow vinyl.
the macintosh amp poweres the front stage active with 100 watts per channel, while an PPI art 600.2 sends 600 watts to the idq10. both amps were provided by the customer.
here is the wiring below the floor, you can see the PPI amp on the right, and the zapco DSP6 processor infront of hte amp
its not tuned yet, but its going in for tuning on thursday, it should sound pretty good in the end, though so far, i am having some reservations about macintosh amps (sorry kwame
) hehe...but we will see how it goes after tuning
Little SQ install in a E36 M3 :)
