I found this amazing thread a while ago, and I thought I could deal with the factory audio, but my disappointment finally got the better of me, so I decided to bite the bullet and upgrade my audio system.
It took me 3 days to get through this whole thread, but it was worth it!
I originally was going to buy the Flax series ( PS165FXE and PC165FE) as
@pro suggested, but based on feedback from many folks including
@p__x recent feedback on the amp making such a huge difference, I decided to go with the Focal Inside "plug-n-play" system instead, IS VW 165 and IC VW 165, and pair that with the Kicker KEY200.4 amp.
I just couldn't justify spending an extra $300 for the Flax series when the Inside series makes such a nice difference when paired with an amp.
I was able to get the IS an IC from Amazon.de, along with the Focal SPK-SIM adapter for $460 including shipping, tax, and currency conversion, which is pretty good.
Based on everything I've read, and my own experience installing car audio, I've got some tips:
- Don't solder! Use butt splices instead. This is what VW recommends. It's much easier, and much more secure. Solder is brittle and can break, particularly lead-free solder.
- As @mitigating suggested, don't waste your money on the ridiculous Focal ISO adapter. It's not made of gold. Several good options:
- Instead of the expensive Focal Impulse harness, you can buy "Speed Wire", like this 18AWG Conext Link MSC918-10 10 Feet 9 Conductor wire. It also comes in 20 ft. for $25.
- For a more "factory look", wrap your harness with friction tape. It keeps bundles together, deadens sound, and protects the wires.
- As others have said, order a bag of retractable door clips (3CN868243) and 2 or 3 A-pillar metal clips (5NA867276B) from your dealer
- I also bought this cheap rivet nut tool for $25 at the suggestion of @Jay_k. It comes with an M3, which shouldn't require drilling, just some M3 machine screws.
Finally, thanks to
@Jay_k for the suggestion of the Kicker KEY200.4 amp.
According to the docs, you aren't supposed to need the Focal Speaker Simulator (IHF06). You just press the "Radio Detect" button on the Kicker amp. However, according to
@p__x,
@fijshion and others, you still get a park sensor error. I'll try it both ways and see.
The docs say:
The KEY200.4 also includes a "Fader" DIP switch, which allows us to just use the front L/R for input, driving all 4 speakers from that. That should help bypass that high treble drive that folks are reporting, but it breaks the factory fader.
Hope this helps save folks some money. I'm planning on doing this at the same time I add the folding mirrors I got from Alibaba, and I'll also add some Dynamat while I'm at it. I'll try to take as many pics as I can!
