Yes its the main power feed and its fused downstream.

Im more than qaulified to work it out as have spent 30 years as chief engineer on business Jet aircraft not to metion some suprsonic cold war jet rebuilds

just wanted to save time as thought someone here would have done it before.

If it's the live feed you need and not ignition then I would take it direct from the battery. You'll also need the appropriate Amperage rating fuse as close to the 12v source (battery Positive +) if you don't do this the cable between the battery and the amp is fully UN-protected and is a big no no IMHO and a fire risk. Sorry I cannot give any more detail myself as I don't have the same sub as you do but there are members on here that do.  Diesel$ Live$ Matter. ⛽ï¸�🛢ï¸�👨â€�🔧🧰⚙ï¸� RED, WHITE & BOOST! 🇬🇧

So I plan to fit under middle row seats but here's the question ... how do you get the wires from the head unit to the sub ? Inside or outside/under ? currently I'm thinking run it down the back of the dash then putting it in black convoluted trunking and running next to the seats, under the rubber middle row floor mats and up to the sub.. any other ideas ?

Personally I would with your wires forget the convoluted tubing because it will be not flexible enough and add to the bulk of it. I would instead spiral wrap it in electrical tape this way it keeps flexible and keeps the diameter small and also some protection too. For routing I would follow along the gearbox tunnel drivers side and follow along through the middle just to the left of the seat runner on the drivers seat. might be easier if you take the seat out too just for easier access. Give me a shout if you'd like any other ideas.

*EDIT* forgot to mention I would go under the mat / carpet too. Mine has rubber the harder material to manipulate but it's possible with rubber and carpet. Diesel$ Live$ Matter. ⛽ï¸�🛢ï¸�👨â€�🔧🧰⚙ï¸� RED, WHITE & BOOST! 🇬🇧
