Audio Upgrade


I've recently been looking up information on upgrading the audio quality (not loudness) of the BMW e46.

I did come across BSW audio solutions but it appears heavily marketted and fishy like they are not the best solution for my money.

Could someone please direct me to an easy to follow guide on improving the sound in my e46 330ci. I find it very overwhelming when everyone complains about BSW ease of install then doesn't provide guides to better solutions.

Again.. I value audio quality over how loud the system can play. My budget is around $1000 give or take a few hundred.

You can always upgrade your speakers and headunit, but to get the most out of them, you need a good installer. He will tune your head unit so your stereo will sound 10000x better than stock BMW audio system. I have a pioneer p99rs in my car, and it sounds amazing, but the HU itself will run you about $1000 new (i got mine used). The headunit will not sound that great if left untuned. It has the automatic tuning capabilities with that small microphone though. But you still need to make adjustments to your amp. Alpine HUs are not as good as they used to be, unless you use the pax and rux. But dont go there unless youre ready to splash out around $3000 total. My suggestion is, go to the BSW website and get their speaker upgrade. Should sound better than stock. If you want more, you can get a HU with Built-in tuning capabilities (time correction, equalizer etc) and get someone who's experienced in audio tuning to tune the system for you. You can go passive but the tuning is not easy too. It all depends on the person installing the system.

Do you have the harman kardon audio system in your car? The HK system is not bad really. The stock non-HK system is rubbish. Utter rubbish. My honda fit sound system sounds much better.
