(Note: Shaun is from South Africa where they get the European Head Unit. This is from an email he sent me regarding his stereo upgrades.)
I recently upgraded the sound system in my car very successfully and with
minimal modification. It sounds fantastic now and I would reccomend the
following configuration and equipment to anyone looking for a good
quality audio system with minimal modification to the looks and
functionality to their GTI.
I used the standard head unit (Blaupunkt 2040) with the optional 6 disk
Clarion CD changer, which means the existing displays and controls
operate as normal. The only modification involved cutting the back out of
the plastic speaker mountings in the doors to accomodate the larger
speaker magnets and cutting out the grid part of the black plastic
covers to flush mount the larger tweeters that I used. Other than that
everything is standard so nothing is visible to prying eyes !
Although the standard radio output is pretty pathetic and has no RCA's,
it can be put through a preamp and then into a decent amplifier. I used
an Audio Control 3in1 preamp which includes an equaliser to shape the
sound and a Rockford Fosgate 400a4 50wx4 amplifier. Its important to get
a decent line voltage coming out from the preamp into the amplifier so
that you get a strong signal. 3-5 volts is recommended.
I replaced the existing front speaker splits with the Rockford Fosgate
FNQ2614 6.5" component speakers. These are a truly kick ass set of
speakers and i definitely recommend them. In the boot I have installed a
Rockford Punch XLC 10" subwoofer in a small sealed box which can be
removed should I need to carry something large in the boot. The box is
very small and you still have a fair amount of boot space left even with
it in place.
The existing rear speakers have been retained and run directly off the
head unit. I have however put capacitors in line with the rear speakers
to filter off all bass frequencies. They simply provide a bit of rear
From the front seats this system sounds excellent, Very clear and with
just the right amount of bass. However, the rear could do with more
midrange and hi's. If you don't often have people in the back of the car,
don't bother with the rear speakers, however if rear sound is important,
I would recommend replacing the rear speakers and amplifying them too.
