Looking to add a couple subs to my already nice sounding H/K system..
I need to figure out how to get the pre amp signal split out to second amp..
Also best spot for remote turn on for second amp..
Last but not least I need to relocate factory H/K amp to make room for sub woofer..

I am no stranger to DIY, retired audio installer so I know my way around wires..just looking to find someone who has done this already to save me some time and head aches...

Thanks in advance for any and all help..

1. "Pre Amp" Signal

There isn't really such thing on the MINI. The signal coming out of the head unit is somewhere between speaker and line level. The same HU is used for all levels of sound system, including the amp-less BOOST system, and the output signal is said to be able to peak as high as 21V. That said, many people (myself included) run the signal into line-level RCA inputs on amps without issue. From my own amp install, I know that I could install it to either the line or high level inputs making up the differences by adjusting the gain.

All that being said, the best place to tap into it is either at the X9331 connecter in the driver's side footwell (search the forums for diagrams and more details, it's been described to death) or the X10226 connector as it goes into the amp in the trunk (also described fairly often). The latter is both a little riskier and a little bit more work. You need to remove quite a few trim pieces plus the back seats to get adequate access, plus there are many more wires in the connecter and they're more tightly wrapped together. As an added bonus, the OBC is tied to the amp, so accidentally crossing or shorting wires back there can cause serious (and expensive) difficulties.

2. Remote Turn On

The X15 connector, beside the X9331 connector in the driver's side footwell has something that can be tapped as a remote turn on connection. Again, another forum search will help you find that - it's also been described in some detail.

3. Amp Relocation

In theory this should be as simple as extending the wires somehow. In practice, you're going to run into issues due to the OBC connections. As far as I'm aware you can remove the amp entirely, but it causes several issues if you are in the dealership for work. The increased resistance in the lines / interference from the junction points / etc could also cause some troubles. A better option might be to do what many others have done and install a false floor in the trunk. You can then use it as a sub box, as well as installing the new amp underneath it. Depending on the vehicle's options, there is also the passenger side cubby.

 

Thank you this is exactly what I was looking for...I have the x9331 connector so I should be all set..
