Bavsound Review

[Tbonem3]

Have any experience with the Carphonics BM53 amp upgrades? Would this be a suitable upgrade with the bavsound speakers?

I don't know it, but if you give me the specs, I can give my opinion.

Some basics:

Class a/b are larger and hotter, but sound better.
Class D has come on leaps and bounds in recent times. If you get a high quality one (like my ARC audio 850), it can be very musical like class a/b. Most cheap ones sound like shit though, and buzz often.

You're not going to hurt a driver with too much available amperage. You'll hurt it by asking it to play (low) frequencies it's mechanically shouldn't.
So go for a good amount of power, but be sure to have active or passive crossovers to slope the frequencies down and protect the drivers.

The fewer the drivers, the better. The most perfect sound system ever would have just one speaker, but that's not physcially possible. For our cars, you'll need a pair of woofers (5.25-6.5") and a pair of tweeters (.75"-1.xx"). Then, you'd need a 8" in IB (ski pass/rear shelf) at a minimum, but truly, more like a 10" in an enclosure in the truck or in IB in the rear shelf.

So the amp would need to be at least 3 channel, but how you get there can depend on wiring. It could be 4 channel, use the the front 2 with passive crossovers to power the front 4 drivers, then you could bridge the rear 2 channels (sum) for a single subwoofer.

Less is more. Have ample amperage, but protect the drivers, and create the right sound with correct filters.

My BavSound upgrades are due in next week, but I was running my HK system with Baris' BM53 update, I did his Stage-2 upgrade with the amps. It is a very noticeable difference and pushed those 21 year old speakers to decent sound, use to be muffled but after the upgrade much clearer. I could only imagine if I had the BavSound upgrade already installed.

Now I've shifted to a Dynavin 9 and I'll be running an aftermarket amp using the TechnicPnP harness I've had for years, probably a 4 channel for the two decklid HK subs and have options for a sub box in the future.

Did you see my earlier advice? Unless the drivers are malfunctioning or deteriorated, you'll only make a big improvent in SQ by replacing the amplifier.

Just installed this set up tonight in my Vert. Completely underwhelmed and disappointed. Running off a dynavin N7, these distort like crazy around 2/3 to 3/4 volume with a flat EQ. I might actually put the stock HK speakers back in. To me, definitely not worth the cost, and I also bought at 20% off

Hey guys, I am currently stuck with my Bavsound speaker install. Never thought I'd say that as my E36 was 100% drop in and go. But I can't find any info on this.
I have a 2005 HK m3, The housing on my rear tweeters are different than everyone on YouTube who has installed them.
I can't figure out how to separate the tweeter from the plastic screw thing that screws into the speaker grill. Without ruining one of the two.

First pic is my tweeter, and 2nd is the tweeter that everyone else has.

Anyone run into the same issue?

Figured it out, They are the same as the sedans, Take a ton of force but after a while they release.

Yeah, the people like yourself who have moved on were definitely pioneers, ICE in our cars is not for the faint hearted.

You had to remind me of that, huh... #facepalm But, as you know, it comes out SO much better. The speakers are in the almost ideal positions for this little cabin. It does't take much to make it punch, but you do have to think your way through it.

Because some of us have already moved past the factory audio bits. But agreed, for everyone who has not, that looks like the easiest thing to do. Maybe not best but certainly easiest.

No, send amp to Barris at carphonics and he can upgrade it. This is the answer and I don't know why everyone doesn't do it.

Just installed CDT audio 6x9 subs into the rear basket. They are an easy direct fitment into the basket. Definitely sounds better and more bass than HK.

But now I’m thinking I need an amp upgrade. Are any of the aftermarket amps plug in play? I’m an audio simpleton.

Baris, your amp upgrade service apply to HKs?

[E11even]

Yeah, the factory amp cannot adequately drive real speakers. They can drive the paper cone stuff that came in the car. The good news is power gets cheaper and easier to add as the days pass. You can get small footprint amps these days that fit anywhere.

The RF 6x9's sound really good in my M3, a noticeable improvement over the stock HK's. I do have the Carphonic's BM54 Amp upgrade maybe that's the difference. After installing them I had to address several rattles from the added bass.

If there was an easy way to wire in an amplifier for my speakers without messing with my harness I am all ears though, I want to retain my factory Mk4 nav unit.

Found this while snooping tonight. https://carphonics.co.uk/shop/parts-...fier-installs/

I tried the Rockford Fosgate 6x9s, but did not have good results. It sounded like bass output dropped and disappeared. I dropped the basket with everything connected to check function and the cones were moving but cone excursion looked noticeably less than with the stock HK 6x9s, which I re-installed. Bass is back to stock levels. Maybe I had a bad set of RFs, I'm not sure. I was pretty excited to try it but then disappointed by the lack of bass.

This was tried on my 330 zhp, but the sound systems are the same / close enough. Maybe I'll try the Rockford Fosgate 6x9s again in my m3.
I know some have upgraded their head unit amps via Carphonic's, and others have simply changed head units all together, but I think for my needs this is sufficient for now.
