BMW Audio Upgrades 1, 2, 3, 4, 5, 6, 7, X3, X4, X5, X6

BCSS audio upgrades for your BMW

At Brian Car Sounds Security we have many years experience on BMW audio upgrading. We've come across that the BMW models i.e. 1, 2, 3, 4, 5, 6, 7, X3, X4, X5 and X6 share almost identical set ups which are run on 4" speakers in the front doors, 6" speakers underneath the seats and 4" speakers in the rear and all are run off the original BMW radio. If you have a Harmon Carmen audio (logic 7) or just the standard set up we can give you an amazing sound for your car.

BCSS supply & fit audio upgrades for your bmw vehicle

BMW Audio Upgrade Package 1

Upgrading the front speakers of your BMW is a fantastic start to a great sound. We start off with sound proofing the doors and the door cards. We then upgrade the front door speaker with an Audison 4" mid range and then add a pair of Audison tweeters and crossovers and this set up can be run of the standard radio to give you a nice clean sound. We start this package at £350 supplied and fitted. As we are part of the Four Masters group we can offer you a 3 year warranty as we are fitting the Audison speakers.

BMW Audio Upgrade Package 2

For this package we are using exactly the same as above but we are adding a four channel JL Audio XD Amplifier to give a much more cleaner and powerful sound, we use this to channel the front mids and tweeters. The other two channels run the under seat speakers by using their crossovers of the amp to get a more defined sound for your listening pleasure. For this audio set up you’re only looking at £950 supplied and fitted. The best part is all products we're using can be hidden so there is no space taken up in your car.

BMW Audio Upgrade Package 3

For audio upgrade 3 we use audio upgrade pack 2 and then we add a set of 8" underseat Rainbow subwoofers. We have some more sound proofing to give that richer defined bass with this installation. Nothing will be on show with this installation everything is hidden from view. This will normally take two of our engineers a day’s work for this setup and is £1350 supplied and fitted. Call us on 020 8645 0655 for advice or a no obligation quote.

BMW Audio Upgrade Package 4

For this package we will offer you a richer sound for the whole vehicle by upgrading the front door speakers with our package 1. Then by upgrading the under seat subs with the Rainbow 8" subwoofers. For the rear of the car we will replace the rear speakers with a set of Audison Prima APX 4 Coaxial and up the power on all speakers using a JL Audio XD700/5 five channel amplifier. We allow a full day’s work for this package to be completed. With all cables, parts and everything we need to complete this job all you're looking at is £1650 supplied and fitted.

The advanced audio upgrade for packages 2, 3 & 4

By adding the Audison Bit Ten processor this will give you a full EQ set up. With this process, we can equalise the original head unit of the vehicle by giving us a much cleaner audio sound into our amplifiers. Once completed we can then time correct the whole vehicle to pinpoint the sound to where we desire it and fine tune the processor to give you that personal sound. By adding £400 to packages 2, 3 & 4 this is a great thing to add and will really enhance your setup.

The above packages are ones we have fitted to cars previously and we've had fantastic results and many happy customers. If you feel theres a certain package for you or something different you would like to do with your BMW, please feel free to call us on 020 8645 0655 or pop in to the shop for a chat about your ideas.

We will take the time to listen and make a system perfect for you.
