I started a thread a few months back but never got round to a decent write up so here it is! There is a link to the old thread here: http://www.talkaudio...polo-6n2-build/
The car: VW Polo Match (6n2), 2001 registration
Equipment: JVC headunit, Genesis 2ch sm60 amplifier, Infinity basslink active sub woofer, Vieta component speaker set with passive crossovers
(please excuse the state of the car in some of the pictures, i started this install before i had given the car a major clean-up!)
The first step was to get some power from the battery to the boot. I chose to take a positive power feed from the nut and bolt holding the factory power distribution bar in place.
I made a short jump cable to run from the positive battery terminal to the fuse holder. A ring terminal was crimped onto the end of the cable, the cable was then soldered in place for a secure connection to the ring terminal and heat shrink placed over the ring terminal for protection.
After deciding where to place the fuse holder i cut one of the mounting lugs off as it wasn't needed
The jump cable was then cut to length and terminated into one of the fuse caps, again heat shrink was used for protection.
This cable assembly was then placed onto the car with the fuse holder and the fuse holder was secured to the coolant bottle bracket.
I then terminated the positive power cable to the other fuse cap and ran the cable across the bulk head along with the brake pipes. The positive power cable runs through the bulkhead and enters the cabin above the brake pedal, this cable runs through a spare grommet next to the clutch cable (ignore the horrible blue cable tie, this was temporary until i bought some more black ones!)
After running the power cable across the bulk head I pulled it back out again so i could wrap it in loom tape to make it look like a factory cable
The fuse cap was then re-terminated and placed back into the fuse holder
With the power cable now in the cabin I removed the plastic kick trim and rolled back the carpet. The positive power cable was then run from the entry point on the bulkhead to the edge of the floor pan, this allowed it to be run in the factory cable channels that run from the a pillar to the b pillar. The rear seats were removed and the cable run from the b pillar behind the rear door card and into the wheel well inside the boot.
