    Well I have done many things for a center channel, some of them are, Mounted a 3.5" coax in and behind the center AC Duct, Under the front defroster in a BMW 5 series. Up from some custom location in the center console. Pioneer makes a surface mount center channel thats not too shabby, the Pioneer ts-cx7, check it out at http://www.pioneerelectronics.com/PU...ication/TS-CX7 As far as a phantom center channel, you do not need any fancy electronics. You can usually set one up by using some cars stock dash speaker locations and mount tweeters up there angled toward the center dome light in your car. (that is under the factory grill) Or by getting some custom kick panels that hold a component 4, 5, or 6" speaker and tweeter in them. They usually come with the right angle on them to set up a phantom center channel. It's all physics my friend. Check out Qlogic at http://www.qlogicenclosures.com/q-products/q-forms/ They have a nice selection of reasonable prices Kick pannels.

    you guys are too technical. hijack, you worry too much about perfectly matching everything. if you setup some rough crossover settings(for 6.5" doors, a minimum of 50hz high pass, for a 10" sub, set a 30hz high pass if possible), you can run a amp that has double the wattage of the speakers.


    the wattage rating on the speakers deals with how the speakers get rid of the heat that they generate. specifically, the ratings that speaker companies use are based on full range audio signals.. by limiting how the speaker uses the available power-- by using the crossovers, so the speakers don't try to reproduce signals that it can't physically reproduce, the speaker becomes more efficient, allowing for better power usage, and also allowing you to run them at higher-then-rated power.

    with your setup, you ought to be using the available crossovers anyways, as that is part of a correctly setup 7.1 system.

    for the center channel:
    i don't know how much more you want to mod your truck, but another option could be a speaker hidden within the air vents by the screen.

    I do not use a head unit. Its 100% car pc. Its uses a SoundBlaster XtremeGamer 7.1 card.

    Well I was going to get two four channel amps. That will push all the door speakers (6), the center, and the phone speaker. The sub would get its own mono amp.

    You know me better then some of my lovers, I am obsessed with matching, LMFAO..... You guys are too technical, shoot, you just lost me too!

    but if I am using coaxial speakers, how do I use crossovers? God I make this harder then it is, but my brain is so weird with understanding certain things.

    Wont hiding the speaker make it sound muffled? Well here is the thing, OMG, I think I have an idea. Not sure if its a good one. I can always mount the phone speaker in a awkward place, as long as i hear the speech. So it can go in the bottom of the dash facing down, etc. Now tell me if this OK. The center console will have 2 screens, one for driver for multimedia and one for the passanger for the same. There is a huge area on the back, side area of the screens. Can I mount them back there, facing into the foot wells? Below is a crude picture as an example.

    You use the crossover on the amp. That arc I spoke of has a built in crossover and independent gain for each of it's six channels.... Perfect for what you are looking for

    it is getting split up in multiple places:

    normally, the speakers get fed a signal that has all the parts of the audio-- bass, midrange, and treble. the coaxial part splits the music so that the bass and the midrange part goes to the big cone(woofer), and the treble only goes to the tiny part(tweeter).

    what i am recommending is to setup the amp to cut away some of the bass--- the coaxial part is still doing it's thing sending the treble to the tiny speaker, it just has less audio to sort through that it needs to send to the big the speaker.

    yes, the vent or under-dash location is going to make it sound a little muffled.

    mounting them on the sides of the console 'should' work, though you might need to consider mounting a center channel on each side to allow the sound to reach both front passengers...

    Wow Really hijackxz1? speakers on the side of the console? That may be good for the phone speaker but if you have any understanding of sound image you would know that that is one of the worst spots for a center channel. You want your center channel like your center channel at home as close to the center as possible aiming straight out and as close to ear level as possible. You want your center channel to be where you would like the persons voice talking in the movie to be.

    And dschmittler, I too have a Car Audio store but I am not trying to sell anything here just try and help a few out.
