I am new to BMW. I'm in the process of searching the right option combination on the M340i. Looks like I will be narrowing it down in the next couple of days.

My question, Has anyone installed a subwoofer into the new G20?

- If so, what was the set up?

I am looking for a powered Rockford Fosgate P300.

Hi,

Like always with BMW it depends on the level of OEM audio you opt for. If you go with H/K there will likely be MOST integration to the amp and you will have to use a MOST integration (e.g. moBridge or similar) or a DSP which can cope with the high voltage output from the factory H/K amp. If you go with regular Hi-Fi with factory amp there is balanced differential low-level from the HU to the amp, or the same high voltage output after the amp. So basically same options as earlier generations.

iDrive 7 changed all that... there is no MOST OEM amp, or separate OEM amp at all anymore. The OEM tuner is now integrated with the HiFi amp (RAM, cannot be replaced), the HK OEM amp (Booster) connects to the RAM and only powers the OEM woofers, i.e. RAM power the component sets, Booster power OEM woofers.

So, with the HK system it is safe to say if I go with a self powered woofer like rockford fosgate p300-10 punch. It would work fine with the existing system? I know that this particular model does not require a remote wire from the HU.

The HK booster should output at least 100W per woofer... that's between 20-26V peak. That p300-10 accepts 3V max -you need a LOC.

Did you ever install a sub in your g20?

After having the H&K sound system it is enough. The sub was not necessary.

Going to be putting a sub in my m340. Have a quote for a custom mounted sub that would sit in the trunk floor with a custom box and metal cover. Would be 2 10in jbl and a 1000 watt amp.

He said 2400 which felt like a lot. I have an existing sub and amp which I was thinking of just bringing over to save money. Do you think best buy would be capable of connecting my existing system to the m340 without much trouble?

I also have a 10" JBL sub from my F30 and wondering if I can put it in my recently ordered M340i with HiFi sound system? I'm a little out of my league with this, as I bought my F30 with a full Bavsound system already installed.

A nearby audio shop said around $500 to install my existing sub and amp
I have the hk system. It's very nice sounding with good stage, bass has some punch but not 500+ watts of external sub which I'm used to. I'm getting ppf and tinting done now so maybe in a few weeks I'll consider it.

Any updates here? I have the hi-fi system in my g20. My ears are begging for more.

You could try with audison, they sell kits for BMW

audison.eu

Or those Alpha One from bimmertech

It's easy to add an amp to the car. I dropped in a 12" solo baric and JL rd1000 Amp and I have the hifi system. Shop charged $150 for install.

I did not. I found that the Harmon Kardon system was enough.

Did you have to run a loc to this?

What are the problems that may a cure not running a loc? I hooked up a 6 channel amp to the factory speakers n one speakers crackles and some times cuts in n out. Also crackles sometimes with acceleration

[TurbroMeca]

Does anyone find that the sub they installed is also playing some of that fake engine noise?

Yes. Mine does. I coded it off with BimmerCode app but it's still there. Just not as bad. Very annoying.

Naw. My amp has a built in LOC. Otherwise it would be needed.

Did you power your Amp off battery in trunk?

Just got my 2020 330i with HiFi audio and not impressed with audio.

For starters want to install my existing 12" Kicker sub and Pioneer GM-D8601 amp. Appears pretty easy since I have a AudioControl LC2i 2 Channel Line Out Converter. Just planned to tie LOC into rear speakers and power amp from battery in trunk.

Trying to make sure no hidden surprises I am not thinking of, as I had unexpected surprises with same setup in my previous Cadillac and had to make mods to its onboard DSP.

Thanks in advance

[Pacman123]

Yeah mine is directly wired to the battery in the trunk
