I’ve taken the plunge and bought a take-off Alpine SWE-1200 sub. It’s the LR model with integrated amp and a single connector (below):

I was hoping when I took out the cubby I would find the appropriate connector - some on the forum have been lucky - but there’s nothing there (and nothing under the cover).

So my question is, is there a loom/harness I can buy (I’ve searched the diagrams and nothing appears and no obvious part number)?

Paul, can you make a full harness?

Or do I cut the connector off and pull the L, R and remote to the dash and the power through to the battery box? This would need to be fused?

I’m no auto electrician so has anyone done this or managed to source the harness?

Many thanks

Hi Martin,

Can you still supply this lead, and let me know how much it is,

Thanks

Mine had the wiring all there but when I hooked it all up it still wasn’t working. Couldn’t figure it out so took it to local autoelectrics place figured out it needed separate power to the sub.

Farmerben, are you able to provide more information on the fix you mention above?


As opposed to start a new thread I have revived this as there is a heap of good info.

I have an MY14 90 Hardtop that had the factory wiring under the cubby, I installed the factory LR Alpine amp and connected, I also connected the cable behind the headunit, 2 x RCA and a grey plug into the existing harness.

The 10amp fuse is present but the sub does not operate.

However, I am running a non-stardard headunit, Stinger Heigh 10, which may be part of the problem? - The RCA are connected to the sub-out RCA's and the Sub is switched on in the Stinger menu, but the sub does not operate.

Any input appreciated

My 2013 Defender came with the factory subwoofer. From almost new I switched to an Alpine flip-out head-unit. All worked fine on that. From what I remember I just connected the 2 RCA's behind the head-unit for audio and nothing else. Used the Mudstuff ISO adapter for all other wiring.

Recently I changed to a new head-unit, but I cannot get the subwoofer to work. The only difference is that the head-unit has only a single subwoofer RCA output, so I bought and fitted a Y-adapter. But still no sound from the subwoofer.

From the plug at the subwoofer I do measure 12v. Does anyone have an idea what I'm missing here? Does the subwoofer need a 'wake-up' signal just like amplifiers? Does it maybe have a fuse inside the unit that I might have broken with my tinkering?

Would appreciate any help here. Next step would be to get Martin's loom to bypass all existing wiring, but his shop is still closed.
