Hi all,

I've been researching either a speaker upgrade or a sub woofer addition to my stock 8 Speaker stereo in my 2013 Passat (fitted with RNS 510 head unit).

Dynaudio upgrade or Fender system (from the US) all look pretty expensive, and even fitting an after market amp and sub woofer still requires pulling out the head unit and messing about with the wiring loom, which I don't have the time or patience for.

So I went looking for a plug 'n' play solution (which requires no additional amplifier and will run direct from existing RNS 510 head unit), and I found these offerings from SouMatrix:

SouMatrix Speakers:

Inspirit: ($586 reasonable value)
Passat Speakers - Inspirit Upgrade Kits for Volkswagen - Soumatrix

Xtase: ($869 starting to get a little pricey)

Manual: (useful resource)

Can any one vouch for the quality of these particular speakers?

Thanks in advance.
