    Default TB3 Upgrade?

    Has anybody done "The Big Three" in there vectra c?

    Basically upgrading the stock earths under the bonnet to limit voltage drop in large audio systems.

    The three are:

    1) Battery to Chassis earth
    2) Charging wire between the battery and the alternator
    3) Alternator to chassis earth wire.

    This needs to be done on my vectra but I have no idea how easy/hard it will be.

    I've heard somewhere that the alternator is incredibly hard to get to on the vec c which might prove very difficult whilst doing this task!

    Thanks for any help guys

    Really anything over 500rms should be upgraded to 4awg.

    I will be running ~2.5k rms

    Done a few installs but nothing near the 2.5k rms mark. You must be planning on running big bass!

    So I suppose you will use a BIG power caps as well. What about an additional battery and split charger.

    I also went for loud (with quality ) but with minimum power- it can be done. What amps, headunit you looking at?

    I'll be running a burning desire 2 (2000rms at 1ohm) running 4 x 12" spl dynamic subs and a DLS A4 (250rms x2) running a set of Oz Audio Matrix components.

    I wont be adding a power cap, they do more harm than good.

    Ideally I would like to add a second battery but as an interim fix I would like to do the big three but even so, it needs to be done to prevent voltage drop no matter what batts you put in there.

    Fwiw, the rest of my system will be:

    Alpine ida-x001 ipod head unit (with 6 cd changer)
    Phoenix Gold EQ25x processor

    And hopefully an audiocontrol epicentre
