• Alpha One A90 Woofer 4 Ohm - Quantity: 2

Installation Time: 3-4 hours for a full set

Here’s a sneak peek of the speakers install:

1. Access the midranges and tweeters by removing a door panel, trim panel or speaker grille.
2. Remove the factory speakers and replace them with Alpha Ones.
3. Reinstall the previously removed trim. Base stereo vehicles require sourcing trim panels with tweeter mounting points.
4. 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.
5. 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.
6. Reinstall the trim and seats.

You will get the exact install instructions after purchase in the form of a PDF manual.
