  1. I like those Kappa series, personally have a set in the back.

    & a set of Rockford P142C on the dash,,,my RF 4" depth was close to 1.6" . with those mounting rings Kappa 42.9 should be fine.

    About the door speakers, the signal is passed. unless U'd modify the factory amp, putting coax(full range) speakers wouldn't do any good.

    I've wanting to upgrade the speakers in my 986 for many years. This is the year! I've been investigating speakers recently and like the sound of the Infinity Kappas.

    A couple questions:

    1. Has anyone had experience installing Infinity Kappa 42.9i into the dash? I'm concerned about the mounting depth and want to make sure these speakers fit before I order them. I saw several posts mentioning successful installs with this speaker, but it might depend on the particular mounting configuration. This is a coax speaker, and the tweeter protrudes from the main mounting bracket by 5/8" and the rest of the speaker is 1 7/8" deep, so I don't know if there's enough clearance.

    Rather than cutting the original speaker bracket, I'm considering using the mounting rings from:

    2. About the door speaker... is the signal traveling to them really low-passed for a subwoofer, or is there a full-range signal going to those speakers? I'm wondering whether I should spend the money on putting coax speakers there or just getting a single "woofer" speaker there.

    Appreciate feedback from this setup...

  2. It is a personal thing,,,

    Everyone should stick to what's recommended by the manufacture.

    G11 & G12 with OAT are compatible with VW/Audi part #.

    Since porsche has changed the color on their OEM antifreeze, Toolplant took a pic of both(VW/Porsche) lables to compare each other.

    I tried to find it , but couldn't

    IMO they are the same thing,,,,,Some belive G12 is the same as GM dexcool,,,

    I've seen this Dex-cool(OAT) ruining thousands of engines + causing some major repair bills(class action suit).

    Why? Probably just because of the fact that when the balance is upset ,OAT can come apart get neglected.

    It is hard to tell U, what antifreeze U should be using.

    Audi's been using the newest version of their AF G-12+(HOAT)yellowish,,, perhaps it's the reason they upgraded to HOAT.

    I personally use Valvoline/ Zerex G-05 for my 986S.

    Coolant, Chemistry, and Corrosion.

  3. +1 - be very careful about slowly running the engine up to operating temp .

    Porsche had to relocate/change the engine block manufacturing plant back in late 90's(could be the biggest reason)?.

    Any cylinder head will crack if its overheated.

    I know most of us are using G11-G12 with OAT anti-freeze.

    But if the sysytem gets neglected, cavitation problem can occur which often causes overheating.

    MB has been using G04 anti-freeze for their cars.
