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-inch subwoofer under the seat and 4″ speakers that are fitted in the front doors. If you’re lucky you may have a door tweeter. Because of the way the system is designed the car original system could have sounded good but the speakers were underpowered and not of the best quality.
- Dynamate front doors
- Alpine custom tweeter
- Alpine custom 4inch front door speakers
- Alpine custom 6 inch under seat sub
- Alpine 4 channel amplifier
This upgrade will help the original speakers sound better as the amplifier in the radio is underpowered, even if you replaced the speakers with better ones, you would not get the benefit of how good the speakers would sound because the new speakers would be underpowered as well. This system will make the music sound clearer by upgrading the speakers and adding a 4 channel amplifier. Dynamate will be added to the front doors making the speakers at front sound better with less vibration from the door panel and also makes the quieter to drive in general. Dynamate front doors.
