I'm looking for an opinion if they're worth getting installed and will the upgrade be noticeable. I don't want to mess about with additional amps or wiring. I just want a straight and simple upgrade for better sound quality.
Will those speakers do the job?
Thanks

Don't waste your money on speaker upgrades. The BMW speakers are quite good. It's how they are being driven that's the issue. Don't listen to audio shops trying to sell you what they make the most profit on. Most are cheaply made Chinese speakers.

The one speaker replacement exception for all of the BMW audio systems is the underseat subwoofers which are subpar. The tiny BMW underseat cabinets is the problem. The highly advertised expensive subwoofer upgrades are not the solution. The best underseat subwoofers that are actually made for the cabinets and have the specs to prove it are Earthquake SWS-8Xi (2-ohm) along with the Earthquake spacer rings. Earthquakes are available at Walmart Online, Amazon and ECS Tuning.

Do you have the base, HiFi or Harman Kardon BMW audio system? The upgrade solutions vary by which you have.

Here are the best upgrade paths depending on which stock BMW audio system a car has.

Both Match amplifiers below add an advanced DSP system that is much better than the DSP system that is included in the HK system. They instantly make the BMW speakers sound amazing.

Base Audio System:
Match 7DSP amplifier. Two specific Match cables to connect amp to your BMW dash unit. The amplifier mounts easily in the trunk in the empty left rear alcove spot.
Earthquake subwoofers and Spacer Rings

You can also add a center dash channel with midrange and tweeter (the bracket should already be there under the dash pad) and add tweeters to your four doors.

HiFi Audio System:
Match 7BMW amplifier. Complete plug and play replacement for your stock HiFi amplifier in the trunk.
Earthquake Subwoofers & Spacer rings

You can also add a tweeter to the empty bracket next to your top dash center channel midrange. And you can add tweeters to your rear doors.

Harman Kardon Audio System:
AudioControl ACM-2.300 LOC/Amplifier
Technicpnp website- wiring harness
Earthquake Subwoofers and Spacer Rings

Everything is fine with the HK system except the weak underseat subwoofers and the power that drives them. The ACM-2.300 is the perfect secondary amplifier to drive just the Earthquake subwoofers. My family and friends thought that I must have replaced my BMW audio system. But all I did was replace the subwoofers and add the right amplifier to drive them.

Hope this helps!
