Interesting idea with the bluetooth.
Can't wait to see where you take this.

Next I wanted to do is to upgrade the Tig sound system with something decent. Being a bit of an audiophile sound quality of stock speakers was pretty harsh to me. So after searching few forum threads I started to disassemble door panels and plastic door sill trims.

All in DIY style

First thing I noticed after removing door panels is how thin is the inner metal plate which speakers are mounted. So dynamated door panels to make sound more deep. Also stock speakers were mounted on two inch tall plastic speaker spacer rings so had to make custom rings which was a huge pain. Finally got some nice MBquarts and installed them.

OEM speakers ( Made in China

)

With the new speakers and door dynamated it sounds much better now. But I felt RNS510 internal amps are not powerful enough to drive upgraded speakers to full potential specially low end of the frequency spectrum. So wanted to install an after market amp. After searching got a Alpine mrx-v70 5 channel amp.

Then started installation. I have never done something like this to a brand new car but temptation overcame the fear

Front door sill removed

Rear door sill removed

Audio out and audio in wires went through separate paths to avoid crosstalk and distortion, this is where audio out and power wires went through.

Audio in wires came from RCD 510 to Alpine amp ended up in here.. ( Had to enable the RCD 510 low power outputs using vagcom cable to get best sound)

Power Fuse Install

Finally Amp up and running

Future plans, Install a sub-woofer

Nice work. Keep us updated with facinating pictures.

Do you use LOC for the Amp, and splice off the plug bundle? And how do you run the power and ground cables into the interior?

Thanks.. I did not use a LOC .. I just enabled the low power signals from VAGCOM cable and My Amp can even handle speaker level signals too.

For getting power (only positive) in to the cabin I use the same hole VW use to run their wiring. When you remove the door sills there are plenty of grounding points all along the OEM wiring so can easily tap in to one or two connections for good ground.

For tapping in to RCD510 wires I used this cable:

Wow. Great detail and it looks good.

I'm wondering, what did you do for the speaker wires. Did you find and tap each speaker wire at the door sil, run new ones from the speakers or tap right up at the deck and then run back to the amp?

Actually, nvmind. I didn't read properly

Start of the second phase of audio upgrade.. Hardest part was to decide the best place for sub.

Sub will go here !

Got a 10 inch MBquart sub which can play as low as 25 Hz

Next tried to find a place to build a custom fibreglass box with not much luck. Decided to build one myself. it is def. not easy work IMHO still work in progress ...

Got a digital sound processor (Audison Bit One) which is capable of doing wonders to the sound quality ..

was thinking of upgrading my speakers. this looks like trouble haha i guess i'll get a professional to do it. the sub location is unexpected! wonder how it will sound on the side panel.
