Another vehicle in our workshop today was this new F25 BMW X3. We upgraded the dissapointing factory audio system with a pair of Morel 9" Elate woofers in the factory underseat positions. We installed the Morel Hybrid 402 component set in the front doors and powered it all of an ARC Audio KS125.4 Mini amplifier. This thing sounded amazing! A huge improvement over the standard system. The best part was that everything was hidden out of sight!
