This is a collection of new and older upgrades I did over the years on my sound system.
Blaupunkt Miami CD127
Over 3 Volts stable and Distortion-Free Low Impendence (100 W) Preamp Output (4-Channel)
In other words a very clean and true signal.
It also has an Auxiliary Input.
Very simple and understated design that I think suits the car very well.
Focal FP 4.75
Class A (Analogue)
4x75W RMS @ 13v (real)
Signal/noise ratio >100dB (A)
Frequency response (-1dB) 10Hz-35kHz
Input sensitivity 0.2-5V
Variable high-pass crossover 50-150Hz (12dB/oct.)
Variable low-pass crossover 50-150Hz (12dB/oct.)
A truly amazing amplifier.
Mounted at the top of the trunk.
5.25" Rockford Fosgate Mid-Bass
4" Swiss Audio Mid-Range
Tweeters and Mid-Range are mounted on the side panels, besides being the easiest and less intrusive position, they provide the most equidistant placement possible.
Three-way cross-overs, mounted behind the side panels.
5.25" Swiss Audio Mid-Bass
Two-way cross-overs, mounted behind the speakers.
6.5" Conrad Johnson.
First of all I had to create a hole at the parcel shelf as I didn’t want to have a big huge box in the trunk.
Next I fabricated a support from plywood that is mounted on the parcel shelf.
I had a square grill from an old speaker and it’s fitted on the parcel shelf, as discreet as possible.
I also made a Low Pass filter as it’s bridged with the rear speakers.
I made the coil my self as well.
This was the most complicated part as I wanted a “factory look”, no cables, FM modulators, or external mounts. I also had to devise a way to make it easy to remove it for updates.
The door pocket was a perfect place.
The sound is taken via a Belkin adaptor that also charges the i-pod and has an audio output that is connected to the Aux input at the rear of the head unit.
I also replaced the i-pod’s 8GB hard drive with a 64GB SSD drive, so plenty of music!
I’ve spent a lot of time tinkering and fine-tuning the system and the sound is, if I may say so, brilliant… mellow and very true with a nice deep but not overpowering base.
It compares with my 2006 Range Rover Harman Kardon Logic7 DSP, 5 amplifier 14 speakers system.
I would actually say it sounds even better… with clearer, deeper bass and mellower trebles.
