Adding a sub with B&O

I picked up a 14 GL63 a few months ago with the B&O option and it sounds wonderful but just missing that little extra oomph so was thinking of glassing in a little high quality sub in the storage compartment in the back where the spare would normally be. I can't seem to find anyone having done the same and I suspect I will be limited to tapping off one of the OE subs and running over to an amp/processor with speaker level inputs.

Anyone have any links with pinouts or examples I could maybe look at? My google fu is typically strong but failing me thus far on this task.

thanks!

Don’t have BO system but added a 12” and amp. Can get pics of the setup tomorrow. Can also check my “Panda Build” thread to see the setup in a few pics.

Wow that's quite the adventure in your thread. Sucks to see you were in the collision but glad they found everything they did. Really sharp looking truck.

Pics for you to see where my buddy tapped to get the signal.

This is behind the back pass side cargo cover, just below the switches to fold the third row down.

Thanks for the pics. I've picked up a shop manual that promises to have all the wiring diagrams in it so should cover me. I would assume the HK and B&O have different wiring.

Integrating a sub properly to an existing complex audio system, is not as easy as putting a low pass filter and kicking in a large driver. Chances are you will first start with 'wow' , where was that bas before and then evolve in to , I think that 'bass' notes are not in synch with the other parts and then you will realize that sub is pretty much detached from the rest of the audio.

I design built DIY speakers and I honestly would prefer to go to EQ settings and increase the bass little bit more rather then trying to insert a sub to an already complex system in a pretty complex cabin.

I have the B&O also and can tell you definitely that the system puts out more than enough bass on its own. The problem with not getting enough bass is the quality of the music signal coming in. Highly compressed music from some FM, but especially Sirius radio make the bass sound very weak. But any decent CD or even streamed music from your phone can make it come alive and really thump if the music calls for it. But if you are looking to go ghetto and make the entire truck rattle with bass and sound ridiculous, then you will definitely need a different sub and amp.
