Hello everyone,
I thought I would share a small guide with what I have found out so far on this topic; of which I know a few members have been trying to figure a solution out to. Much of the information can be found in this thread
Aftermarket headunit with bose sub and amp?
My car is a hatchback (this guide may differ for saloons/coupes), and when I installed my headunit I kept hearing a click at the rear when it turned on indicating that the BOSE amp's power was still connected and turning on. However no audio came out of the sub. This mini guide shows you how to get audio output through the sub.
What You Will Need
1 x Coaxial RCA (Any male RCA to male RCA lead, yellow composite for example. Mine was about a metre long which was enough cable)
1 x RCA Y Splitter (2x Male to 1x Female)
Soldering Iron, craft knife, glue gun/black tape (tools to remove passenger seat and centre console)
1.
Take coaxial cable and cut off one end. Carefully strip the wires back exposing both the inner wires like shown.
The white inner wire is the positive (+) and the shielding wire around it is the negative (-). We will solder these to the respective bass wires on the equaliser connector.
2.
Remove the front passenger seat (4 bolts - take care with the plastic covers on the rear tracks) to allow access to the equaliser underneath.
Disconnect the green connector cable on the equaliser.
Locate on the connector the "Light Green" wire (Bass +) and the "Green/White" wire (Bass -). These are the two wires we will solder to the Coaxial. Below is an image from the Honda ESM manual showing the connections.
Cut or expose the wires how you wish, I personally chose to just bare the inner wires and tap into the connections and left the connector disconnected.
Solder the wires, Light Green wire to inner RCA wire (positives), and Green/White wire to outer RCA wire (negatives). See pic below.
Once soldered, shield the wires separately. I used a hot glue gun and covered each soldered join in blobs of glue, before wrapping them separately in black tape for extra precaution.
3.
Undo the centre console and feed the Coaxial RCA through past the handbrake and gearbox. At this point you may want to remove your dash and headunit and connect the Y splitter to the respective Sub Pre-Out. I personally left mine in and using a torch and front-facing camera on my phone (yes I was lazy lol) managed to connect it this way. Once that's done connect the two RCAs together.
I do notice that the colour of my RCA differed. This is because the first time I cut the yellow one in half, to see the wires and realised I cut it too short. It makes no difference and connected fine.
4.
Tidy up any wiring, replace the seat and then give it a test. It should be working and you should hear a small but noticeable improvement in the lower frequencies. It may require some setting up on the headunit (i'm still figuring out how to tune mine, but it sounds good enough for me).
Please, if there are any improvements/corrections needed, do let me know and I will happily apply that as soon as I can.
I hope this will be of help to anyone looking for some direction.
