    My 3143 crossover upgrade

    Hi!
    This is my experience with 3143 upgrade.
    First I must thank Mr Grumpy, Mr. Widget about coils and hjames on how to re-use honey wax on the crossover.
    Parts used:
    I core Mundorf for woofer and Air core for the rest (all Mundorf)
    72uf Solen PB series for Woofer
    52uf Solen + 4uf Evo Silver Gold Oil and 20uf Solen to ground for Mid
    4uf Mundorf Evo Supreme and 13.3uf Evo Oil for High
    1.5uf + 1uf Obbligato Premium Gold for Ultra High
    Wired all with Solen silver plated copper teflon insulated

    First picture must have this one with original crossover with all wires identified becouse I have found that the picture that is going down the web includding this forum is wrong with the 20uf connections.
