My new amplifier upgrade

[PowerSax]

If you have HK, you could still run this amp if you're willing to replace all the speakers at the same time, with say, the BavSounds speakers for non-HK cars.

...but is the wiring plug and play? or does this make it so?

Someone could reach out to Techniq and see if they would do something custom. It wasn't that long ago they were selling E46 harnesses. I got one within the last 2-3 years. Attaching some files here that might be useful. Whatever you do, make sure to ground your amp with everything else in the driver's side trunk area near the backseat. Grounding to the battery is no beuno.

Yeah I contacted them and they never gave me that option. Good point on the grounding. I grounded on the driver side.

I wanted to update this post with my two new additions to the Match amp upgrade. The new Sony 6000 double din head unit and my Audison Prima 10” powered subwoofer. (yes i know the wires are ugly) lol Have something coming to cover that for the clean look. Also I would like to report I have had no issues with the Sony after the latest firmware. Now on to the subwoofer. This little subwoofer is amazing!, the sound is finally good in the M3. Hopefully this helps someone with their decision.

This conversation sounds familiar...

GreyM340i What cable/adapter did you end up using to hook up the amp? Also, any idea how the 7 channels are wired? My Hi-Fi/676 setup has 10 channels from the stock amp...

I know I know. Been really busy and no time to go to the storage to find it.

The Match UP7 BMW comes with the correct harness in the box. Not sure how it’s wired. Just know it works well and the E46 hi-fi system as far as I know is also 10 channels. Wish I knew more.

Ebay has some Technic knock-offs I've seen for E9x, might be worth looking for E46.

Technic used to make the harness however good luck finding one now.

I have one. I would need to find it but I know I have it lol

I think the hard part there would be the harness, which is one of the benefits of an aftermarket head unit (good luck getting someone to build harnesses for these cars). Then the DSP amp becomes PnP. Getting one with the source SQ, functionality and stability becomes the issue. So far I've been pleased with the N7Pro, not the least of which reasons is because all of that back end wiring to go to an outboard amplifier (or multiple) is already done. From there, I can upgrade head units as necessary. Also, the separate subwoofer control at the source was a real game changer for me.

I’m not showing a direct plug and play application for the E46. It would be best for an authorized dealer in your country to check the car and amplifier, there may be a compatible harness that is not showing up in the upgrade finder.

So unfortunately there is no option for us HK optioned M3 guys 🤣🤣

Thanks for the update. So the only option for HK would be a harness and a JL or Audio Control multi channel DSP amplifier

My current amp is running 35W per channel, which, for the most part, is more than enough for my 51 year old ears. The problem is that the music I’m streaming from Apple Music outputs at different levels, some songs are super loud, and other songs are just a a moderate level, even though the volume is maxed out. Gets even worse with the top down, so the step up to the 85W/ch would be just to give me a little bit more headroom, I don’t ever plan to max it out at that point.

The 6.5 are rated to 150W and the tweeters 210W, so they’ll be fine even at the higher wattage.

FYI, if you go to Settings > Music > Sound Check and turn that on it should help level out the volume from song to song on your iPhone.
