    Perfect

    Well done assembly, everything works, cable lengths OK, practical as there's no need to connect a power supply to the battery + earth if coupled with an adaptor going to the original wiring harness (not included in this kit, see photo).
    The cabinets just fit under the seats, which have become vibrating as an option haha.
    The amp has practical power settings, and for the price and space it takes up, it does the job very well!
