Have recently changed my e46 m3 for an F80 so are inspired to do another audio build. My previous system evolved over a 5 year period was raspberry pi based and was controlled by the bmw Nav head unit. Had dsp and 2 x components speakers front and back and a ski pass vented subwoofer. Audio was digital to dsp and music was mainly from lossless Flac cd rips. Amps were 110 rms x 4 class AB and 600 rms class D on bass. System was tuned to run up to 80% of amplifier power to avoid clipping. For a car audio system it sounded quite good. Move forward 14 years in tech the F80 is far better in terms of taking most forms of usb / Bluetooth/ DVD audio sources. This one has NTB id4 which is the last of the text based menu system and the build is 6 months too early to get the newer gui interface and CarPlay/ Android auto software. The F80 I have has been imported so spec is interesting. Has connected bmw modules, can self park , lane control etc but has only the base audio system for some reason. But from my point of view it’s ideal for an audio upgrade as not too many speakers to replace. This thread will be about uplifting the audio system to above HK level. Pic courtesy of Pete

Just over a month of ownership, and easily the best car I've ever owned in terms of power, handling, comfort and just sheer enjoyment. Glorious.

Looking forward to the e46/v10 build, that’s the dream right there. Please document it.

Sold.

That’s awesome, if only all car salespeople were that honest!

I didn't know Johnah Hill from Super Bad did rage reviews. He missed the shitty fuel flap that slaps around on windy roads.

Have ordered a Mobridge Most25 8.1.1 Amplifier https://mobridge.us/product/mobridge-most25-amp/ This is a single box solution that contains 9 amplifier channels and DSP. It behaves in the same manner as the BMW Harman Kardon digital amplifier but has substantially more power. It’s also power efficient. Has some really nice features such as 10 channel DSP for time alignment and frequency controls on each amplifier. From an IDrive point of view Mobridge have coded the amplifier to be fully controlled by the IDrive. It supports all audio Sinks so you still get 4 channel PDC in surround, front audio for nav and telephone audio plus usual idrive music options.etc. All the factory sound controls functions work such as fader and equaliser. The two factory audio presets map to Morbridge DSP maps which is handy as I’ll be able to run 2 different Tuning curves so one for driver position and one tune for when passengers in the car. With the amp being MOST based music is fully digital from the idrive system. So Basically DDA in the audio path. Great for reducing system noise. Amp / DSP will be configured in the following way. Power is peak rating at 4 ohms Channel 1&2 Front L / R tweeters 150 watts x2 3500hz to 20;000hz Channel 3&4 Front Door L /R Mid bass 150 watts x2 150/200 hz to 3500hz Channel 5&6 rear door components running passive crossovers 150/200 hz to 20,000 hz Channel 7/8 underseat woofers 300 watts x 2 ( running 8 inch HK 7 ohm speakers so 150 watts expected ) 70-150/200hZ Channel 9 Boot subwoofer 2 ohm 800 watt. 20-70hz

Ordered some second hand F3x Harmon Kardon underseat 200mm woofers and enclosures These will replace the base audio woofer enclosures and their 17cm woofer. The base audio woofers sound a bit Bose esk with an overblown 80-90hz bass region and then roll off quickly. Will put in a box so I can revert system to standard as I did with last build. Hk enclosures have larger air volume than base audio although both vent into side sills. Apparently the combination of enclosure plus side sill gives a enclosure equivalent of 0.6 cubic feet ( info from Bill Fitzs on another forum ) The HK woofer size is ideally suited to that size. It’s close to 8 ohms and is run to about 125 watts on factory amp. Going to try and improve on the HK woofers although they do come up well and a number of drop in upgrades actually don’t model as well. Have chosen new after market SQ oriented 8 inch drivers and looking to run these from 55hz to 150-200hz. These will get roughly up to 300 watts so can be driven to mechanical limits with low distortion. The unknown is if I can get the factory grill to fit. Going to be tight fit ! TBA LOL 😀 Also brought F30 HK speaker grills for door midbass and rear tweeters. These look to be far more open than Stock / HiFi option First picture, base audio underseat woofer , Second HK.

It’s a hard comparison at this stage as owned and drove the e46 m3 about 130,000 km / 11 years verse 2000 km so far on the f80. The e46 felt so connected to the driver and the road. Ergonomics are great and s54 is such a great sounding engine and a nice level of progressive power. However, the F80 is more modern and I do need a 4 door these days. Power wise my M3 was around the 180kw at the wheels mark verse somewhere between 310 -330. There is a massive difference and it’s easy to have the back brake traction off the throttle.The f80 is a very stiff car to the point where I do have trouble with wheelspin coming out of my driveway. Ive had time do a 3 point turn and reverse up a couple of times. What I do like is 3 settings for suspension, engine and steering weight and having two steering wheel buttons with saved settings, M1 commute, M2 … smile 😊 Still getting used to it and trying to stop those e46 things you do but looking forward to a track drivers day to explore my new limits. I didn’t keep the e46 as budget wise I’d made a refresh list that was similar to the cost difference of the F80 and I’m guilty of have a couple of other vehicles that just don’t get used ( or finished )
