Want to add a subwoofer or new front speakers without cutting your MINIs wiring? We get lots of inquires about our Plug-n-Play Wiring T-Harness that taps into the X9331 connector. These are now available through Audio Overstock on Amazon.

This product is not supported by Integral Audio. We are making it available to help the DIY community that would like to reuse their own equipment or build their own systems. This is a pilot program to see how it goes - we may discontinue it so if you've been waiting/looking for this I'd recommend getting it now!

[Edit/Update 3/28/2016: These were discontinued for a while, we've brought them back due to demand. I'm going to try listing them on the integralaudio.com website and see how that goes. You can buy them direct now here: https://www.integralaudio.com/index....-harness.html]

 

$99 , wow. At $49 I'd consider it.

 

$49 would be great, I agree. But since the materials alone cost almost that much, that would be a bit tough. You can thank BMW and TE for that - the connectors are proprietary, and expensive - the pins and sockets will run you more than $1/ea from your favorite online supplier. Plus the $300 hand tool you'd need to crimp them properly (ours are done on a $16k+ K-press, the die alone is an additional $3k). And the $100 tool you'll need to remove them when you make a mistake stuffing the connector (you will, trust me!). And your time. You'd also need to make a replacement for the RCAs which are custom made - they have passive components soldered in under the overmold, they are necessary to get the your OEM HU to get along with your aftermarket amp.

Eventually someone in China may knock off the connectors, but for now the only options are this or cutting the wiring. Cutting the wiring is free of course, unless you make a mistake or want to resell the car

If I could sell them cheaper I would. But I can't.

 

I agree actually. We buy and make a lot of that stuff where I work.
It's expensive.

 

Would this allow me to install the Alpine 445u amp without having to run new wires or splice into the speaker wires near the plug? I won't be adding any other amps...just want to get more power to the front speakers (replacing those).

 

Excellent, good to see IA still making new stuff for us MINI people.

 

Kevin, any idea why there is 132 Ohms of resistance on the signal side of the RCA's and 85 ohms on the ground side? On all 4 RCA's?

 

This is designed primarily to install a traditional aftermarket amp. The idea is that this simplifies traditional amp installation to the same level as the 445u. The differences are that you still need to power the traditional amp, but you are also not limited to the low power output of something like the 445u.

I should note - again - that this isn't a supported product, and is provided as a courtesy to the DIY market (we get large numbers of inquires regarding selling just this harness). We can't get involved trying to support installation of other products, provide advice, troubleshooting, etc. I would if I could, but we just can't. Support costs would be massive and the margins are minimal on this.

 

Yes, you are seeing the passive circuitry that is built into the RCA overmold. This circuitry is necessary to get the BTL transistors in the OEM HU to get along with an aftermarket amp. It also knocks the signal down from 7V to about 4V max, avoiding clipping the input stage of aftermarket amps that can't handle that signal.

Without this circuitry you'd have problems in a significant portion of MINIs and aftermarket amps.

 

I was going to buy the Integral Audio part off eBay, thought the price was a bit high so I considered just cutting / splicing wires. Then I thought I would just order the parts and make my own harness. I asked for a quote from my local Mini dealer for:
qty 1 - 61131378129 - housing - $13.48
qty 12 - 61131376204 - receptacle - $43.20
qty 1 - 61131378137 - housing $9.80
qty 12 - 61131376193 - pin - $68.88

That's a total of $135.36 CAD just for the parts. It would also take a couple weeks because they'd be coming from Germany. That's nuts.

 

Your first post on NAM basically points out that $99 for the harness is cheaper than you'd think? Thanks! I made these available because it was easier then constantly saying to "no" to folks, and the majority of folks who purchase these weren't considering our Soundstage anyway. We don't really make any money on them (just enough to cover the cost), it's really just as a favor to the community.

You can find the bits cheaper than that, but not cheap enough to make it worth your while unless your time is only worth a few bucks an hour. The real expensive part is the proprietary hand tool for crimping.

Also, if you are seeing something on eBay, that isn't ours. Ours are only listed on Amazon. The Amazon reseller was just a pilot to test it out. It hasn't been too much trouble, so I may list them on our site at some point.

 

Not sure why I typed eBay, I meant Amazon. When I went to edit the site was unavailable so I gave up.

I'm in Canada so the parts are harder to come by. Doesn't seem like any of the well-known dealers in the USA will ship parts to Canada so I'll have to bite the bullet and buy this harness.

 

I order a pair from amazon yesterday but is says they are currently out of stock and it will take 7-10 days to get more in stock :[ I guess I wait until then

 

Now they send me and email that they cancel the order because I didn't respond. I still want the wiring hardness what should I do?

 

Not to worry. Just place the order again once they show as back in stock. Should be in about a week.

 

Now that I have I can say NO WAY those pins cost that, look like good old MOLEX connectors, I got hundreds at work if anyone needs them.

But the labor cost to build at my shop $125 an hour won't make it possible for me to make .

 

They aren't Molex, they are TE. TE has the largest share of the auto market, Molex is a distant second. If you work with these at your job you are familiar with the fact that there are dozens of different critical dimensions on a given pin/socket, and there are literally hundreds of thousands of different pin/socket sizes/designs, and they aren't interchangeable.

These particular parts are made by TE for BMW, and are proprietary. That's why they are so expensive. I can assure you BMW is paying a tiny, tiny fraction of that price when they buy them from TE.

 

It does work well, I can say that. makes for a cleaner install and saves time.

Only change I would make is add a strain relief to RCA cables, I just zip tied it to speaker cables.

Also back IN STOCK for those needing

 

If only it shipped to Canada...

 

Okay. ELI5... Would I need one for each front speaker and one for a sub/amp?

 

It does ship to Canada....

 

You would just need one harness.

 

Not for me.

 

Out of curiosity, what does this do? Err, in other words, what about the factory head unit doesn't get along with a basic speaker-level input on an amp? Does the signal dip weirdly at some frequencies or something?

It's awesome that you have decided to sell this. My budget, sadly, doesn't stretch to your full system, but this part should save a lot of headache as I put together my not-so-fancy system this month.

Thanks!

 

I just realized that it's not clear to me if this provides a low-level or high-level input to the amp. Probably high-level? Can anyone confirm?
