Ive fitted one
Its very very easy. No need to even touch the stereo one bit guys.
Firstly obvs run the live to the battery. I followed a Corsa D guide on where the run the wire through and theres a rubber bung behind the scuttle panel that you can push the Live wire through. I'd highly advise to start from the engine bay to the sub, because where this rubber bung is...its extremely hard to push the wire through from inside the car.
Anyway the Earth goes to the Rear Seat Mount where it attaches to the car body and obvs key the area up before wedging the earth between the bracket and car body.
The Remote Wire goes to your 12V Socket...As Vauxhalls turns off when you turn the car off un-like Ford's do. Now this I ran under the carpet and down the centre console past the handbrake etc and its very easy to unclip the panel holding the 12v socket, USB & AUX etc and simply wedge it into the LIVE of the 12V connector.
Now your sub has the power and also able to switch on and off.
Now to give it sound I highly recommend removing the Passenger Rear Quarter panel which is very simple, a few clips holding it in place etc.... You dont necessary need to completely remove it, just enough to reveal the speaker that is hidden behind it and lucky enough you can clearly see the wires that go into the speaker.
Now you need a RCA to Bare Wire converter....I used FLI's version which I've had for about 3 years so dont know if they still make them. Anyway wedge the bare wires into the speakers wires entering the speaker itself...ONLY use 1 pair of the wires as there is 4....LEFT & RIGHT, honestly doesnt really matter with a sub.
Now connect your RCA's to the RCA - Bare Wire Converter and now the Sub has sound.
When all wired up make sure your ignition is on so the 12V is working and this will switch the sub on and BOOM the subwoofer should be working perfectly.
This whole process took me about 2-3 hours as I was very cautious not to damage anything and took my time with it all and its a lot easier than it sounds....Trust Me
I would highly recommend the Sub I'm using the Vibe SLICK 12inch Active as its small, but powerful and as you can see in the picture I've painted the Wire Cover Plate Brilliant White to match the Car
