Source Sounds recently completed a stealth boot install in my Octavia, along with new front speakers and some additional little tweaks. The work they have done has been immaculate. You would never know the anything had changed, until the music starts that is. The improvement is immense. I just want to take my car for drives, just to listen to things.

I highly recommend Source Sounds. Excellent work, very helpful and knowledgeable staff and excellent aftercare and support. I wouldn’t go anywhere else for my ICE needs.
