I hope you are wrong because I just ordered the Match Up 7DSP amp and Match PP-BMW 1.7RAM. That was based on the guide for my car from the Audiotec Fischer find it guide on their website.

[Daywalker007]

Correction…It appears the Match 86DSP will work and seems to be the closes physically to the one bimmertech sells. The Match 7DSP has different volt/watt/ohms numbers than the 86DSP but I could not say how that translates to which unit is better quality.

Assuming you have a G20, this is right one anyway.

BimmerTech amp is their branded PP86DSP.

[Daywalker007]

Based on what AustraliaG20 and 1WickedE90 posted it looks like I picked a compatible model and maybe one that is better than the Bimmertech version. I did not get the MEC add on but I don’t think that is necessary if I am only looking to upgrade the amp and keep the factory speaker set up.

I guess I will find out if the Match Up 7DSP has to be connected to the battery even with the Match PP-BMW 1.7RAM harness. I was under the impression that the PP harness allowed for PnP replacement without having to run a wire to the battery. They get delivered today so I will post again after I install to confirm.

@1WickedE90 did you have to run a wire to the battery for your install?

[AustraliaG20]

Pretty sure you'll need the MEC analogue in otherwise you won't have enough channels. You will also need to run power from the battery, if you download the manual you'll see the harness plug on the amp have no the power pins.

Also, based on all my more recent posts the amp draws more power than the BMW OEM harness can handle. So you need to run another power and ground.

Looks like I have some research to do before the install. I am a bit confused by your post as it seems like you are telling me I need 2 power and 2 grounds.

Also, I only have 7 speakers that I am aware of and the 7DSP has 7 channels, at least that is what the Audiotec Fischer website states. If the amp draws more power than the OEM harness can handle then what is the fix? I have no desire to rewire my entire car to accommodate the amp. Are you referring to a specific harness that is easily replaceable?

Daywalker007 I haven't done the install yet but was told by the Audiotec Fischer sales engineer & local dealer that the amp will need to be wired to the battery in the trunk. Below is a link to the amp manual:

https://www.audiotec-fischer.de/medi...P-7DSP_Web.pdf

Look at page 18 & 19. I will be ditching the stock speakers & doing the full Audiotec replacement (speakers & amp). Good luck on your install!

[AustraliaG20]

Yea my post was confusing, but if you look at the manual you'll see the power pins on the amp where the harness goes have comments about do not use. You need to use the separate power pins by running a cable from the battery and another ground. You only need one each.

With the MEC have a read of the harness you got and the following

MATCH PP-BMW 1.7RAM
The 7-channel UPGRADE wiring harness PP-BMW 1.7RAM enables the simple connection of a MATCH UP 7DSP amplifier with MEC ANALOG IN module to selected BMW models from 2019 with a factory RAM Receiver Audio Module.

By the way, I've got this in my car already and I've got a separate power and the MEC addition

I am still a bit confused on the MEC. The description on the website describes its use as a way to add blue tooth and a line in and other accessories. No where on the website does it state there is a necessity for functionality of the PnP harness and amp to work properly. I am not saying your are wrong. Only that the experiences from you and others isn’t reflected on the Audiotec Fischer website. When I look up MEC on the site it offers me several options like BT HD, Analog In, USB interface, Aux in, and Optical in.

If you are saying I need MEC for proper functionality with the OEM setup then are you saying I need the analog in and if so what function will the analog in serve if this is a digital based amp?

I have not received the amp yet so I am not even sure what comes in the box. I orders it here in Germany so hopefully it is all the proper wiring and items to do the install. I have received the PP-BMW 1.7RAM harness.

The UP 7DSP has 4ch analog inputs and 7ch high level outputs standard, because it is the generic version of the UP 7BMW, the direct replacement of the old HiFi OEM amp in in the F-chassis 3-Series. That old OEM amp had 4ch analog full range inputs, and 7ch high level outputs.

So the UP 7BMW was a full plug and play install in the F-chassis because it used the 12V/ground power connections of the OEM amp just removed and all its inputs and outputs directly. No need for a battery connection in the car for the UP 7BMW.

The G-chassis OEM amp is called RAM, with no analog inputs and 7ch outputs. The RAM cannot be replaced with an aftermarket amp just because it is also the radio tuner of the iDrive system. No RAM, no radio, no audio. So whatever aftermarket amp is installed in a RAM system it must be connected directly to the battery for power.

Therefore, to install the UP 7DSP in the RAM system it requires battery connection, 6ch analog inputs to create a full range input signal (front, rear, woofers signals, no full range signals in the RAM) to create 7ch high level outputs (front, rear, center, woofer) in your G20.

The MEC Analog In module adds 2ch inputs to the UP 7DSP, making it 6ch inputs capable. The UP 7DSP requires the MEC Analog In module to work in the RAM system, otherwise it will not.

Encanto,

Excellent explanation. Thank you. Guess I need to order one more item.

Would I have been been better off getting the 7BMW or would I have still needed the MEC analog in and seperate battery wires?

The UP 7BMW would have required the MEC module and direct connection to the battery as well. The connection issue is the RAM system, not the UP 7xxx amp selected.

[Daywalker007]

So after purchasing the Match Up 7DSP I realize that it is not exactly plug and play. At least not as simple as the one sold by Bimmertech which is the 86DSP as stated by George41.

What is different about the 86DSP that makes it not require the MEC Analog input and separate battery wires? The 86DSP was also cheaper by about $50

Starting to wish I would have just bought the 86DSP unless I am missing something.

[Encanto]

The BimmerTech amp has 6ch analog inputs standard, so it does not require a MEC module.

The BimmerTech amp requires direct battery connection - the RAM has a 20A fuse, the BimmerTech amp has (2) 25A fuses. The RAM fuse will blow if you power the BimmerTech amp with the RAM 12V line and try to get max power output to your speakers.

Protect your RAM by using battery for power.

Got it. You are a wealth of knowledge Encanto.

So I bought the 7DSP for 799€, the PP-BMW 7RAM for 99€, and the MEC analog input for 99€. It sounds like I should have bought the 86DSP for 749€ and saved 248€. The Audiotec Fischer website says the 86DSP comes with the PP harness. I am contemplating returning the 7DSP, harness, and MEC unless there is a performance difference that would warrant keeping the 7DSP.

Change my mind……:-)

Audiotec Fischer has no harness for a PP86DSP and the RAM system.

Hmm, it says 1 x Plug & Play connection cable PP-ISO 2 (2.20 meters). It was not specifics on what this would fit. So if that harness doesn’t fit then I would only save 149€/$170 after buying the required harness.

Unless you are saying that they don’t make a harness for the 86DSP to fit the G20. In which case I would ask how Bimmertech makes that model work in the G20. The video from Kies Motorsport doing the Bimmertech install shows complete plug and play with the RAM and no separate battery wire connections. Unless they just didn’t show that part. That video and the simplicity of the install is what prompted me to attempt to purchase the amp from Bimmertech. Then they told me I could not buy just the amp so I was determined to buy the same setup without buying the speakers. That is the reason for all the questions.

[Encanto]

PP-ISO 2 is a harness for Quadralock connector systems; the RAM does not use a Quadralock connector.

BimmerTech creates its own RAM/PP86DSP harness.

The PP86DSP install in the G20 video only shows the system installation but not how loud the new system will be without blowing the RAM fuse.

You can check the fuse ratings of your OEM RAM radio in the fuse box card in your car, and compare them with the PP86DSP fuse ratings in its data sheet in the Audiotec Fischer website. They do not match -pun intended.

Encanto,
I get the feeling you are in the audio/electronics profession. You are quite knowledgeable about this stuff. I appreciate your patience and help answering these questions.

The instructions for the 7DSP instructions appear to instruct installation of the positive wire to the battery with an inline fuse. That sounds like the only thing I don’t have at the moment.

I hope to take some pictures when I do the install and maybe assist someone like me in the future.

And the ground wire... and some way to mount it.
