    Should I use my head unit, or leave it out?

    I'm adding a carputer to my car, but I'm not sure if I should keep my head unit or not.

    I have a JL 4channel amp for the speakers and a one channel for the subs. Now I'm wondering if I should take the digital out of the Audigy 2 sound card i'm going to use and put it into the digital in of my head unit (Eclipse 8454). Or if I should just go straight out of the sound card into the amps.


    Thanks

    That's your decision to make.
    Here's some questions to ask yourself:
    Do you want a master volume control? Do you want an easy AM/FM solution? Do you want an alternate means of playing CDs (or other media your headunit plays) in case the PC crashes?
    Have you looked in the FAQ yet?
    How about the Wiki?

    I've gone the pc only route. I'm finding I don't like the lag times for things to happen, the wait for boot up, the loose of am/fm radio, and the just general need for all this extra gear (relays, filters, etc).
    I won't give up the computer, but am about to put the head unit back in so I can usb my compter directly to it.
    my biggest PO's with the computer is the boot time for short trips, the popping and cracking on startup, and the inability to turn the volume up and down without having to look at the touch screen (can't feel a knob or button and have to look away from the road) or being able to do it quickly (stereo is always too loud when I shut the car off!!)

    Sure, these probs can all be fixed with extra hardware, or I could just put my high end head unit back in and enjoy the extra functionality of the computer and the head unit.

    Just my .02

    This is a decision I am still fighting with myself on. I want badly to put the touch screen in my Double DIN opening but then I don't have anywhere convenient to put my head unit. My latest idea is taking my rearview mirror down putting the 7" touch screen there and hooking up a rear view cam. This way I can still put the head unit in the dash, have a rear view mirror when needed and use my PC for whatever else I want. It will take a little bracket modification but I think I can make the monitor fit just like a rear view mirror..tilt and all.

    This will give me the easy AM/FM, instant sound with no boot delay and with Aux input on the head unit feed the audio from my pc to the stereo.

    Remove the HU is the last option in my list. The only reason to remove it is when there is NO other place that you can install it.

    I had an extra slot in my dash for a cd changer which was being used for just a storage bin. I moved my head unit down and installed a motorized flip up monitor in the din slot. This allowed enough room for me to slip a slot load dvd for the pc in the same spot with the monitor.
    I open the monitor when I want gps internet mp3 or video, and close it when it's not in use or too bright for night driving.

    maybe a motorized or flip out monitor might be a solution for you?

    cheers

    Doesn't a mazda 3have a flip up on dash?

    I think I remember seeing a picture somewhere of a Mazda 3 install where they installed the screen in the compartment that pops up from the center of the dash. The same spot where the factory NAV option gets installed.

    depends whether how much space on your dashboard you can utilize as well, you can go with headunit, and flip screen, or more factory looking fabriction.

    Personally i am going with pc to amp, no headunit, cause i don't have a space to mount , a headunit, and i don't wanna mess with the face plate connections.

    if you go with AUX headunit, you might have a problem with dual volume control, and improper gains, when you pc volume as a 50%, and H/U 100%

    also depends whether you can wire pc to your factory amp, or swap amp, anyway the most important budget, you might have to end up making a complete audio makeover
