Mk3 Leon st subwoofer wiring
- Thread starter James_FRwagon
- Start date
So I haven't been able to hear as well as I would have liked this week, with a cold and all. Clearing up now though.
I generally listen to rock music, and would rarely have dance tunes on in the car, so take this with a pinch of salt. I also play bass, hence wanting a little more than the stock speakers, though they're fairly decent.
Pros
Adds subtle depth to the system
Makes it easier to hear the bass when driving at motorway speeds
Does what it's supposed to do
£100 - fairly cheap
Easy enough to install (once you get a little help)
Cons
One puts the sound off balance, I hear it all from the passengers seat (earth lead not very long, wouldn't reach to the drivers side, I'm not sure if there are any earth points on the drivers side)
Clarity isn't the best, it adds depth but can be a little muddled when complicated bass lines come in.
Improvements
2 of them, I think this would seriously improve the sound and be greater than the sum of the parts.
Maybe upgrade the speaker to say the focal ibis, which would be a little clearer I think.
All in all, I'm very pleased with it and would do it again.

I was looking at maybe upgrading the speakers in the doors. I did also think to fit 2 of them should cash permit at some point. As you said it does add depth to the system.
Exactly what I thought so that's what I did. And it made a big difference in spreading the bass around the inside of the car.
Also mine sounds better 180° out of phase. Yours may differ......
When I was looking about, I think focal had a specific VW golf set you could buy, which would be a straight swap.
Though the Leon speakers are decent imo

I have tried it 180 out on mine but it sounds better in phase for me.
Yea they are fairly good for OEM none Seat Sound spec, however I'm always looking for upgrades
According to the wiring diagram for my car (2016MY with MIB2 High - 8 speakers) the wiring is different to 'Wastedagen's' diagram,
the rear/right speaker bass & treble are connected to pins 1 & 5 on block A, the rear/left speaker bass & treble to pins 4 & 8, the front/right treble to pins 2 & 6, the front/left treble to pins 3 & 7, the front/right bass to pins 9 & 13 on block D and the front/left bass speaker to pins 10 & 14.
Looking at the plug on my car this looks correct as the wires going to pins 2, 3, 6 and 7 (front treble spkrs) are thinner gauge than the other pins.
When Seat Sound is activated pins 9 & 13 are connected to the subwoofer and pins 10 & 14 to the centre dash speaker, the wires that were on those pins for the front left & right speakers are connected to the corresponding pins used for the front tweeters.

Just put of curiosity, I assume I can just extend the earth cable? It's not long enough to reach below drivers seat. Would I just get a 14 guage wire and connect the two with and cover with electric tape/ heat shrink?
The amp might have a high-level input already - if not then a brief Google puts a hi-low level converter at £5-10 off eBay.
Sorry to bring up an old thread but does anyone know if it would be ok to put a quad lock extension harness between the media unit and the existing harness to splice the sub in to the speaker cables?
Thinking it would be easier to do the splices on this first and would also save damaging the car wiring
Here’s one like I’m thinking of, although it’s now out of stock -https://www.amazon.co.uk/Most-Quadlock-Extension-Connector-Adapter/dp/B00I0YXNTI

yes, I just did this this weekend, was a bit of a struggle getting wires from glovebox through to centre console but managed it. would of been easier to take the whole glovebox out but I like to do things the hard way!
Thanks I’ll get one ordered up and give it a go this weekend.
Edit:- Have just been looking for a quad lock extension and there seems to be 40 pin and 52 pin ones, which one did you use?

I'll have a look after work and see if I have a link to it...
this is the one I'm using..

in-case anyone's interested this is my project that I'm half way through, just got the sub wired up this weekend actually but only to the OEM head-unit and standard speakers. sorry for the bad picture! if there's any interest I'll start a proper thread on it.
