Success! The dream has been achieved - a massive upgrade to subwoofer capacity with a straight drop-in hooked up to the existing wires. The biggest obstacle is trying to find a dual-coil 8-ohm sub just like the original. The key to the solution is that you don't have to. Because the two sub channels from the existing amp can run in "bridge mode", so instead of 2 channels at 6-ohm 150W, it runs as one channel at 3-ohm 300W. That means you can connect a single coil 4-ohm sub! I used one of these babies, which fits the basser box perfectly (including the total enclosure volume), has just the right power rating, and a great sensitivity to get the most out of the relatively weak input. All you need to do is take a positive input from one channel, and a negative input from the other channel and connect them both to your unit. As per the attached picture, the wires are colour coded (grey and white for each channel, red and brown lines for polarity) so it's easy to work out. I paid a guy to do it for me, and he was able to splice the wires and keep the original plug, so in theory I can put it all back to OEM if I wanted. A$135 for the sub A$220 for the box A$100 for the install Less than $500 all up, and the results are phenomenal. Very, very happy with the outcome!

Came here to find a solution to this problem, but just seems to be lots of people with the same gripe! My MY15 Octavia remembers the previous Driving Mode, but my new MY19 Kodiaq doesn't, even with key personalisation. Surely there's a way to fix this?

Ha, I don't plan on doing anything myself. Was just going to source parts then take it all to a professional to get it done. Just wanted to make sure it would all work in the first place though! Guess I could always go talk to the professionals *first* and see what they think 😛

Could you plug both sets of wires into the one set of connectors? I'm keen on the basser box, so as not to take up any space. But I'm blowed if I can work out how you're supposed to connect anything to the existing system without running a whole new amp setup?

What happens if you only plug in one set of wires? The Basser custom enclosure only seems to have 2 plugs, so not sure how you'd even connect both sets of wires?

So any 8ohm sub would work?

Is this actually that big of a problem? I'm a complete noob at this whole thing, but from the little I've read it would seem that dual coil subs are actually made to give you flexibility in what they can connect to, by changing the total impedance if you wire them in parallel vs in series. But it shouldn't be necessary for a replacement to also have dual coils, just to have the same total impedance. This seems to say the amp is designed for a total 4ohm impedance. So presumably any 4ohm sub would work?

Could I maybe use one of these instead? http://www.daytonaudio.com/index.php/sd270a-88-10-dvc-subwoofer.html

Did you find a solution to this one? This looks like the perfect "low touch" upgrade to make the Canton system that little bit more rounded....
