Installation Guide

Here’s a sneak peek of the speakers install:
- Access the midranges and tweeters by removing a door panel, trim panel or speaker grille.
- Remove the factory speakers and replace them with Alpha Ones.
- Reinstall the previously removed trim. Base stereo vehicles require sourcing trim panels with tweeter mounting points.
- Unbolt the front seats or remove interior trim of your woofers depending on their location and release the factory woofers from their enclosures using a heat gun.
- Plug in our Alpha One woofers – they are equipped with gaskets and supplied with self tapping screws to secure them to the OEM enclosures tightly without any glue.
- Reinstall the trim and seats.
You will get the exact install instructions after purchase in the form of a PDF manual.
