  • Grand Sport Subwoofer/Hifi Upgrade?

    Hi. A week and a thousand miles in and very pleased with my Grand Sport SRi.

    The only thing I'd like to improve upon is the entertainment system. It has the Nav 900 unit with the larger touchscreen and I find it just a little lacking both in bass and in separation of the sound frequencies. Trebles are also a little harsh.

    My first thought was to fit a subwoofer, or pair of, beneath the front seats. I don't want anything "gangsta" in the boot. Just something to enhance what's there.

    Has anyone else changed or added to their setup?

    Thanks in advance.

    I've replaced the centre speaker with a midrange and tweeter, replaced the door tweeters, and fitted two subwoofers in the wheel well and two surround sound channels in the boot walls.
    I used a transformer to bring the level of the headunit speaker output down to line level, and feed that to a multichannel amp under the front left seat.
    That then drives the centre, doors, and surround speakers.
    It also drives two dedicated subwoofer amplifiers in the boot.
