EARTHQUAKE X84SWS - 8in Underseat Subwoofer for BMW — Overview
The EARTHQUAKE X84SWS is a shallow 8-inch under-seat subwoofer built for tight factory enclosures where mounting depth is the limiting factor. For BMWs that use under-seat woofers, that matters more than flashy watt numbers because these cars do not give you much room to work with. This 4-ohm version is the one to look at if your amp setup is designed around a 4-ohm load. Gaskets are included, which helps cut down on plastic-on-plastic buzz after install.
I would pick this when your stock under-seat woofer is tired or weak and you want to keep the factory location instead of building out a trunk sub setup. It makes the most sense on BMW chassis with under-seat woofer layouts like many E9X, F3X, and G2X cars, but you still need to verify basket depth, connector, and enclosure fit before ordering. Compared with generic shallow 8s, this is aimed at the actual packaging problem BMW owners run into. If you are still on the base audio system, just remember the speaker alone will not fix weak factory amplification.
