BMW’s baby gets a pretty poor audio system from the factory, as do most of the range, so we’ve found the best solution for the following cars:
BMW 3 Series (E90,E91,E92) 2005>
BMW 1 Series Coupe (E82) 2007>
BMW 1 Series (E87,E88) 2004>
Other kits are available for other cars, please follow this link:
The system is designed and manufactured by a German company called Jehnert (J is pronounced as a Y). Unlike other upgrades for these cars this has been specifically designed for the vehicles, taking into account the vehicle’s acoustics and done without compromise.
Jehnert have a long history of making hi-end audio upgrades for German cars (though they do now cater for some Peugeots, Mazdas and Vauxhalls) and like all things German are built to the highest specification and with huge attention to detail and quality. The goal has always been supreme audio quality but maintaining the factory look of the vehicle-in this case the only way you could tell it was any different to factory is to listen to it-a few seconds will do!
These impressive kits can be bi-amped so you can run an amp for the midrange and tweeter with a seperate one for the woofers or you can wire them as a single load for a large 2channel-the RMS rating on these kits is 130wrms per side-I’d personally advise an amp of at least 2x 150wrms to give you plenty of headroom and a low noise floor. This customer went for the IPA1601, with 2x 300wrms on tap for huge dynamism and the ability to keep the gains right down.
