    wanting Double DIN, but also FM on car pc?

    Hello,

    I have a 2006 Subaru Impreza that only has 2 DIN spaces. I've thought of the single DIN screen tied into an aftermarket deck, but I hate the look of two seperate devices.

    So I'm thinking of the following:

    Centrafuse 3 +
    Double Din screen (I'll pick the model later)
    probably the new Habey BIS-6620-I (z510) pc
    and I intend on running GPS, SIRIUS satelite, Bluetooth, and I would like to have FM radio available as well.

    The question I have is around the FM tuning, and how to drive that sound adequately for my car without a dedicated deck ?

    I know I need to get an FM Tuner (probably the CarTFT FM Tuner), with the adapter to fit my stock antennae.

    My big problem is how to run the audio so that i'm not driving all 4 doors (which are 6"+tweeter) and future subwoofer off of the pc (which I know isn't enough power at all).

    Any suggestions / help / pointers / thread links are very welcome on this.

    search the audio forums for different solutions

    -boiled down-
    regular head unit [+'s = cheap, fm tuner, easy -'s = too easy]
    automotive amplifier [+'s = common, most wattage, -'s = wiring, placement,]
    motorcycle amps [+'s small, some tiny diy kits, -'s ?quality?, low wattage]


    foreseeable issues:

    shut down controller
    running out of usb port fast
    ?dvi connector? ...maybe

    For FM get the VISTEON HDZ300 or DIRECTED DMHD1000 HD radio tuner and use Mitch's adapter (this thread). For amplification, the simple way is to just use a multi channel amp to run to all your speakers, they come in all sizes.

    Sadly I live in Canada, and HD radio doesn't exist up here in the same bandwidth as the US (the morons here in charge, thought it would be a good idea to use a format from EUROPE!... >< ) Besides I like my sat radio, I just want local FM tuner that won't break the bank.

    And the fact that as ShortyDoo said, limited success above 100Mhz channel freq. I don't listen to AM at all, so that I don't care about.


    So I'm going to do a 4 way Amp (probably Alpine, as my speakers are from them as well, most likely a Alpine MRP-F300 ).

    Hopefully I can find an elequant solution to the FM radio issue.

    Really? I've never heard of this happening. I did a quick google, but did not find anything...maybe I didn't use the right search words? I have one, but haven't installed it yet so I can't tell you if this is happening to me.

    You can still use the Directed unit. It's designed with HD radio in mind, but can tune in regular FM stations as well. It's basically just an add-on tuner.

    I'm not sure what you mean about a format from Europe. I thought the Americas (including Canada) were using the odd frequencies, ie 99.5 99.7 etc. If that's the case the Directed unit should work.

    The problem isn't the frequency itself, it's the decoding format. The US is the ONLY country currently to use the IBOC format (In-Band On-Channel format). The rest of the world (including Canada) have officially approved a format called Eureka-147 DAB (Digital Audio Broadcasting) format.

    The DAB format is considerably better in the fact that every channel has it's own true bandwidth, whereas in the US it a much narrower band-channel and has limited expansion (ie: no nation wide channels).

    So, unfortunately 99% of most current HD Radio hardware is designed for the IBOC format here in North America... which excludes it's functionality in Canada.

    Sad... but true.

    On a side question... amplifier decision:

    Alpine MRP-F300

    Or

    Rockford Fosgate Punch P400-4

    Connected to Alpine 6 1/2" Component set in the front, and Alpine 6 1/2" speakers in the back.

    I plan on eventually having a sub with it's own small AMP seperate (but that's down the road).

    Thanks for pointing out another reason why it sucks to be Canadian. Thankfully...you still for XM as an option. Good luck with the Habey BIS-6620-I; this looks like a real contender if you can install it successfully. I Hope you'll post a worklog and give us a review.
