    2004 Deville Stereo Install

    This is my first post so I hope to gain some knowledge from you guys. Thanks in advance.

    I have a 2004 Deville (yes, BOSE)

    I have a Pioneer p-4400 ... brand new unit , never installed ... got it on black Friday, the $ was right, but Ive been sitting on it since due to mechanical repairs taking precedence ... (after 1.5 yrs I have it running at a level I am satisfied etc, now the stereo gets replaced)

    I HAVE the unit, PAC steering wheel adapter, parking brake override (will get a color rear view cam w color)

    I NEED to replace the speakers and start new (I live in buffalo, car is from Fla , winter morning at about 0 degrees started the car on with the volume cranked accidentally and blew the speakers)

    A lot of conflicting reports online.
    I believe there is a 10" sub in the rear deck
    5 1/4" speakers in all 4 doors
    2" speakers in the pillars
    and a indash speaker I am not so concerned about ...

    A - Is this correct ?

    I am looking for a very clear crisp sound. Not looking for a performance thumping system, but want a quality sound, I am considering

    JL Audio 10W3v3-4 10" Single 4 ohm W3v3 Series for the sub
    JL AUDIO TR525-CXI 5.25" for the doors
    (having trouble finding 2" tweeters?)

    B - Help or recommendations ?

    Thank you

    Know that the original Bose HU is part of the car's serial data bus and TheftLock system. Read the threads on complete installs and go from there - you'll need the whole enchilada, from HU to amps to all wiring to speakers - and the wiring jumpers/harnesses that allow you to even start and drive the car.

    Crutchfield (auto audio) has a site for this stuff ...............
