BimmerTech - Amp Upgrade - Hi-Fi (F3x / F8x)



If you don't have HK system in your F3x, not to worry.

I upgraded the speakers to BavSound Stage 1 shortly after I purchased my F80. I was much happier with the sound system, it's more in line with the HK system in the E90. However, it was still a bit weak. I find myself being at the 75-80% volume level. Although it's very clean and no distortion, I needed more power to push those wonderful BavSound speakers. All evidence points to a weak factory amp.


I installed the BimerTech Premium Audio System, it's essentially a heavily modified Audiotec Fischer Match PP 82DSP amp with custom bracket and cables. This amp is about 4 times more powerful than the Hi-Fi system. The installation took me about 45min, it's pretty much plug and play - almost. This is the first amp kit designed for BMW (no splicing, drilling, or cutting).


Impression: After the install, I downloaded the Audiotec Fischer PSP PC - Tool v3.11. Nelson from BimmerTech sent me the files to load for a setup with BavSound speakers. The sound is loud, I had to turn the volume all the way. I coded ASD off and turned all the door gong down to the lowest level.

This system is exactly what I'm looking for. Loud, clear, and highly customizable. The Hi-Fi system doesn't allow any EQ setting, the DSP software provided by Audiotec Fischer is very intuitive and powerful - 30 band eq, crossovers, time alignment, and output level adjustment (HK guys will drool on this setup). I used to keep the volume at 75-80%, now even 50% is loud enough to shake the car.

I played a few songs to test to sound. Keep in mind I'm not an audiophile, but I enjoy music and have a very keen ear for sound. I enjoy everything from country to hip-hop. Like them all.



Hotel California by the Eagles - Clear guitars, great vocal, and smoother than before.
This Girl is on Fire by Alecia Keys - This is the best drum song in modern day. Big bass, tight snares, and beautiful vocal. I can better distinguish the instruments and the bass is much nicer.
Butterfly by Bassnectar - Great song to test out the highs and the system delivers. Smooth highs and nice vocal.

I'm now 100% happy with my system. I highly recommend the Hi-Fi owners to look into this, even with OEM speakers. After dropping money on BavSound S1 and BimmerTech, I'm good with sound system. Anymore and I'll have to trade it when they offer B&O for the F8x.

For those who's looking to buy an F8x, check the damn HK order box then get BavSound S1 with your HK system to call it done. Don't buy a nice car with Hi-Fi (basic sound).



DYI


Tools: Ratchet, 8mm socket, 10mm sock, T-40, large flat head screw driver, and trim/clip remove tool (I used the one supplied by BavSound)

Step 1: Remove those 4 panels in order as numbered. 1) pull out 2) 1 clip 3) 4 clips 4) pull out
Step 2: Remove quarter panel cover. 4 clips and T40 bolt (bolt is covered by a small plastic trim piece of the anchor)
Step 3: Remove the amp retainer. 1-10mm nut
Step 4: Remove the amp bracket. 1-10mm nut and slide the bracket towards the front of the car
Step 5: Remove amp. 1-8mm bolt and wedge it out with a flathead (as shown)

Install everything back in reverse. Secure loose cables with 1 zip tie. Plug the 14-ft USB in first, it's not easy to access once the amp retainer is installed.

There's no need to unplug the battery terminal. Just turn the volume down or power the car off.

Download Software v2.93: http://www.audiotec-fischer.de/cms/l...p-pc-tool.html

Ask Nelson for the appropriate sound file (upgrade speakers or OEM speakers)

Big thanks to Nelson @ Bimmer-Tech for introducing me to this amp. This upgrade was well worth it and I will stand behind this recommendation to all Hi-Fi sound owners._a__a2_

Have you priced this particular amp/DSP in the market? Not any amp, this PP82DSP

I can install a $25 amp in any BMW. I am not saying that it will work, but I can do it.

$750 at Crutchfield without cables makes BimmerTech look like a pretty good deal.

That is exactly without...

- pre-wired 100% PnP harness for OEM HiFi
- mounting bracket
- pre-tuned for your F30

... and with exactly the same 2-year warranty.

Has anyone that got the basic HiFi system ever simply replaced the amp and kept the original speakers to see how that sounds before going BavSound Stage 1?

Seems like everyone replaces the speakers first and then the amp. If you do both I'm thinking that the system that the OP put in would be around 1600 bucks - is that correct. The OP has not been back to update one question posted - how much was the system upgrade?

Any thoughts? I have ordered my 435 and did not get the HK system and am pretty sure that I'll need to upgrade in some similar fashion. I just don't want to spend anymore than I have too. The HK system option was 850 - I tried to change my order but it was in production 2 days after I ordered the car - damn. I called on the second day - once in production you cannot change the order. So that's my situation.

Thanks

That's right!
But there is one more thing that makes it even a better deal - BimmerTech PP82DSP has been modified by Audiotec Fischer to work with BMW HiFi system much better than regular PP82DSP.

It's available exclusively at BimmerTech.

Good amps go around that price tag + this thing is plug and play, If OP says it did a major upgrade on his system might be worth the money. Gonna get it in the near future maybe.

Question though, Will it power all speakers including center?
Also whats your opinion on underseat subs? Change them or does the amp boost them up?

Can tweeter be added to the rear speakers, Bav have the connection to add them on all speakers.

I currently have bav + a powered sub. Does anyone know the spec of the original bmws amp? Want to compare it to these.

Thank you.

Most of the BimmerTech PP82DSP and JL Audio XD600/6v2 installs that I perform are with OEM speakers. To me that is the most effective upgrade for the price.

Now, if anything is lacking with the OEM HiFi speakers is the tweeters. Any decent silk aftermarket tweeter replacement will fix the lack of detail of the OEM tweeters.

Three questions:

1) I've heard questions concerning the stock sub woofers - anything you can add on that note? Pardon the pun. This is actually great advice and just what I hoped I'd hear - that it's not the speakers near as much as the amp.

2) You mention "silk" tweeter replacement - what are those and where can one get those?

3) Will there be an acceptable level of improvement if I don't do anything but the amp upgrade - it sounds like that is true. Would you agree.

Thanks for your reply to my post - hope you see this one.

I have a F32 with HK. The HK sounds pretty good but the low end bass is lacking due to lack of a sub. Thinking of getting full bass upgrade for ~$1700 from http://musicarnw.com/musicar-certified-sound-for-bmw/
Not sure how much will it cost to get it installed locally though...Anyone used them before?

This is a Plug and Play system so it will run the center channel.

The stock subs aren't really subs at all, the amp that is being talked about is a plug and play system, if you want more bass, then add an external amp, and decent amp will do, but it will take space up in your trunk...

replacement aftermarket tweeters are much better then what the stock ones are, but one thing you need to remember is, the stock speakers are at 2 ohms, not many after market tweeters are 2 ohms. Sound coming from car audio is so subjective, some people love Dyna Audio speakers some do not. Some might like brand A tweeters and others will like brand B. Go to a local shop and listen for yourself. But if you want an easy upgrade for your car audio in your BMW start with this amp, and go from there.

- PP82DSP can be DSP tuned for individual channels crossovers, slope, Parametric EQ, output level and time alignment.
- XD600/6 has more output power, analog gain and crossover adjustments

I find the PP82DSP as better sounding amp due to its multiple adjustments and the 56-bit DSP clarity and stereo separation. The XD600/6 is louder but not better sounding by design, it is just an amp.

F30 OEM woofers are good sounding with aftermarket power (up to 100W RMS). However, I found the old E90 HiFi woofers better sounding than the F30's due to the F30 OEM woofers being shallower. The F30 OEM HK woofers sound the best with aftermarket power (150W+ RMS). They are really robust and 7ohms so they can take a pounding.

Audison, JL Audio and CDT offer individual sill tweeters for sale. JL Audio C2 tweeters come with inline crossovers that can be terminated with OEM connectors for 100% PnP install.

Yes, it will be a significant upgrade even with OEM speakers. Just the improved clarity, loudness and stereo separation with the PP82DSP will impress.

Hang onto your money. BavSound has replacement speakers, it should make your HK system much clearer and a bit louder. As for subs, BavSound and another brand I can't disclose will release their underseat plug/play subs very soon. It will be less than $1700, way less.

Yes, a member on Bimmerpost F30 got the amp w/o BavSound S1. Here's his exact quote:

"First impressions: much more detail and extended "punch" in the lows and the highs, even with OEM speakers. The sound stage is A LOT better." - Drew46
