A Vibe installation we did for a customer in his Vauxhall Astra SRI, we installed 2 sets of Vibe 3D component speakers one set into the front doors and 1 set into the rear quarter panels, we drove these off a Vibe stereo 4 amplifier. We also fitted a Vibe CBR S12 Twin Evo that we ran off a Vibe Bass 1 amplifier. Both amps powered off a 2 farrad power cap.
