You already have the speaker, is number 6.
This kit upgrades the sound the speaker makes with a Maserati OEM Sound Ecu, a SoundBooster Bluetooth module and all the parts / wires needed for the install on the i8.
Also lets you manage the volume, intensity, "rhythm", idle sound, start up sound, linkages to the car modes via a phone app
Update: we managed to make it sound like the exotic lambo v10 today, I'll post a clip later
