    CarPC to Factory Bose Amp

    Is it okay to wire from a 3.5mm output on a PC directly to the inputs of a factory Bose amp in a 2003 G35? Does the amp want high or low level inputs? Does the PC provide high or low level inputs?

    Thanks!

    PC provides very low level inputs (On the scale of 0-0.5 or 1volt). Generally lower than most amps are rated for. I can't speak for Factory amps, but most amps you buy in the store have low level inputs as high as 8v in some cases. You need to find out, perhaps from a G35 forum or look up the actual part number of the amp, what kind of inputs the amp takes.

    I would assume it is expecting low level inputs, but factory installed amps can be all sorts of weird things.

    I just did a head unit install on a mid 90's Camaro with the factory Bose system and I did have to use as line level convertor to lower the input level so chances are, yours needs a low level input.

    Yes, you will need something to go from the CarPC to the Bose amp. Let me dig through my pile of supplies from the various installs I have done on my 05 G, and I might have something that will help.

    Cool, thanks guys. I did just order a PAC-LD10. Right now the audio is fairly clear but is flat as you could imagine. Bass is non-existent. I hope this helps. I may have to rip out the rest of the Bose stuff at some point anyway, we'll see!

    I know im a few months late to the post. I also am looking to do a build and the furthest i got was how to get pc sound to the stock amp.
    Now I have found this device.(ROEM-NIS2).
    It allows aftermarket head units to adapt and be plug and play into the bose system.
    Now the question is based upon the allowed inputs What would it take from a pc audio device output (soundcard or interface) stand point to give me PC outputs that can be splice/merge into the aftermarket harness inputs

    LEFT FRONT LOW LEVEL (+)
    LEFT FRONT HIGH LEVEL (+)
    RIGHT FRONT LOW LEVEL (+)
    RIGHT FRONT HIGH LEVEL (+)
    LEFT REAR LOW LEVEL (+)
    LEFT REAR HIGH LEVEL (+)
    RIGHT REAR LOW LEVEL (+)
    RIGHT REAR HIGH LEVEL (+)
    LEFT FRONT (-)
    RIGHT FRONT (-)
    LEFT REAR (-)
    RIGHT REAR (-)

    or what hardware be required to give me these sorts of outputs from a pc

    Splice the stereo output from the PC and attach it to both the left and right low level inputs, that should do it! FYI I had to use the PAC LD-10 in order to get decent levels.
