Carhifi

Today, car manufacturers are subject to fierce competition and are forced to save weight everywhere due to the Co2 reduction targets. This is also clearly noticeable in the quality of the installed hi-fi systems. We have specialised in compensating for this shortcoming and offering you top-class hi-fi quality. Our range of services includes the sale of HiFi products in all price categories, professional installation without compromise and the adjustment and computer-aided calibration of HiFi systems. Of course, a completely retrofittable installation in leased vehicles or similar is also possible! In the following, we would like to describe the individual products and activities in more detail:
Nowadays, many vehicle manufacturers build their models on an identical or similar vehicle basis. This saves costs for the manufacturers and enables us and the manufacturers of the hi-fi components to offer packages for a large number of vehicle types. For example, BMW vehicles have been almost the same over the last 15 years in terms of how the hi-fi system is built.
Here you will find upgrade packages for...

BMW

Carhifi BMW Basic

BMW has been using a similar radio concept in almost all of its vehicles since around 2005:
This results in two upgrade options in the basic version:
  1. If you only want a more powerful and richer bass range, you can install an active subwoofer in the boot.

2. if you have the middle hi-fi equipment (BMW equipment code 676), you can replace the original amplifier with a vehicle-specific amplifier.

Carhifi BMW Advanced

BMW has been using a similar radio concept in almost all of its vehicles since around 2005:
In the Advanced Upgrade, the speakers in the doors would now be replaced and, if necessary, tweeters would be retrofitted. In addition, the subwoofers under the seats are replaced. The amplifier is a 4-channel amplifier that supplies the upgraded speakers with more power.

Carhifi BMW Professional

BMW has been using a similar radio concept in almost all of its vehicles since around 2005:
If you want to achieve a significant improvement in all areas, you would change all speakers: Front system, rear system, subwoofer and centre speaker. In addition, an 8-channel amplifier with significantly more power and digital processor technology is installed.

Mercedes

Carhifi Mercedes Basic

Mercedes installs a similar hi-fi concept in many vehicles in the more recent model years:
In the C-Class (W205), GLC (X253), E-Class (W213) and S-Class (W222), two 10 cm mid-range speakers are fitted in the doors at the front and rear. In addition, the driver's and front passenger's footwells each have a mounting for bass speakers in the bodywork, although usually only the passenger side is equipped. The mounting places for the tweeters in the mirror triangles are also empty in narrowly equipped vehicles. In the centre of the dashboard sits a centre speaker, which is used for the hands-free system, the emergency call system and sometimes also for hi-fi playback.
This results in two upgrade options in the Basic version:
  1. If you only want a more powerful and richer bass range, you can install an active subwoofer in the boot.
2. if you only want to enhance the bass range without sacrificing space in the boot, you can retrofit the second subwoofer chassis in the driver's footwell and supply it with more power via an amplifier.

A 4-channel amplifier is installed as the amplifier, which supplies the improved speakers with more power.

VW

Carhifi VW Basic

Mercedes installs a similar hi-fi concept in many vehicles in the more recent model years:
The Multivans and Transporters of the T5, T6 and T6.1 generation are popular and proven vehicles among craftsmen, private individuals and campers alike. The hi-fi concept is mostly similar here:
There are 16 or 20 cm woofers in the doors and the corresponding tweeters in the dashboard or A-pillar.
There is usually plenty of space under the seat consoles for amplifiers and/or subwoofers.
This results in two upgrade options in the Basic version:
  1. If you only want to improve the bass range without sacrificing space, you can install an active subwoofer under the passenger seat.
2. if the tired high/mid-range sound is what bothers you the most, change the door speakers.

There is usually plenty of space under the seat consoles for amplifiers and/or subwoofers.
In the Advanced Upgrade, the speakers in the doors would now be replaced and the doors would be insulated to prevent rattling noises. In addition, a subwoofer is installed under the seat. The amplifier is a 4-channel amplifier, which supplies the improved speakers with more power.

Motorhomes

Carhifi Motorhomes Basic

Since the loudspeaker systems installed in motorhomes in recent years are among the simplest on the market, there is a great need for improvement almost everywhere.
A distinction is made here between partially integrated and fully integrated vehicles.
In fully integrated motorhomes, 10 cm speakers are usually installed at the front and rear, which are very weak in bass reproduction.
Semi-integrated motorhomes have 16 cm speakers in the doors and sometimes tweeters in the A-pillars. In the rear living area, 10 cm speakers are usually also installed.
This results in two upgrade options in the Basic version:
  1. With semi-integrated vehicles, even replacing the front loudspeakers brings a significant improvement
2. in fully integrated vehicles, larger speakers are built into the top of the dashboard.

In the Advanced upgrade, the front speakers would now be replaced and, if necessary, tweeters would be retrofitted. A subwoofer is also retrofitted. A 4-channel amplifier is installed as the amplifier, which supplies the improved speakers with more power.
When placing the subwoofer, you have to look individually at the possibilities offered by the year of manufacture and the conversion variants for concealing the housing.
