Fitment

Soundtech does not list model years for this package. If you are not sure your car matches, send us the VIN or build date and we will check before you order.

Installation and tuning

Soundtech lists its plug and play packages mainly for dealer and professional installation, although MATCH based packages can suit a confident DIY installer. The HELIX URC.1 SCP is a DSP amplifier, so it needs setting up for the car once it is fitted.

Warranty

Soundtech, the Australian distributor, gives its products a standard 12 month Australian warranty. That is on top of your rights under the Australian Consumer Law.
