BMW Silver Audio upgrade.
If you own a BMW, you will be amazed by how good your car can sound. Most BMWs come with 6″ subwoofer under the seat and 4″ speakers that are fitted in the front doors. If you’re lucky you may have a door tweeter. The original audio system could have sounded good but the speakers were underpowered and not of the best quality.
Silver package replaces the speakers, adds an additional amplifier to the audio system, transforming the sound to give clearer mid range and deeper bass.
- Alpine custom tweeters.
- Alpine custom 4″ front door speakers.
- Alpine custom 6″ under seat subs.
- Alpine 4 channel amplifier.
Fitted price £1400
