    my point is your expectations of 100-150 are un realistic for the amp setup.

    Can a 2 channel AMP be good with this?

    With a 2 channel amp you can still run those speakers (front and rear)

    if you run them in the following manner.

    front speakers in series to each other
    rear speakers in series to each other

    front and back sets in parallel

    this would give you 4 ohm total. but the front will be much louder than the rear.

    if the front speakers are small this may not work at all.(may end up being too much power to them depending on the amp you get)


    before setting something like this up, its important to find out the wattage rating of the speakers.

    You guys prob. understand this better then me

    thanks again

    sorry, that wiring diagram isnt my strong suit but what i would say is this: 2 things: when you pull the HU (as i assume you have/can) you should find some sort of a wiring pinout for the back of it (on my audi's it is just a little sticker with a pin diagram). Look at that and make SURE its not just a switched 12V. if it isnt, you may want to consider relocating the HU to some other (obscure) location and leaving the BUS (sic?) which apparently turns on the AMP plugged in but tapping the line-inputs to the amp and using them for your computer sound. I dont know much about amps (other than subwoofer amps), so i cant really help in the door speaker amp department.

    Good luck

    thanks guys for all the info/suggestions, Ill check for the pinout on the back of my HU

    Dam all this is confusing
    Im just gonna bring to a couple of pro install shops and see what they say and make them do it(just wiring the system audio w/PC)the indash screen i can do and has been done before by a buddy of mine - here is a PIC of his setup, LCD screen in his dash no carpc & no touchscreen though

    OK guys I decided to spend the extra cash and get a 5 Channel AMP,
    CHeck this out - HERE - any good??

    Now my next question is can this AMP be used with my current stock speakers setup @ (front) have 2 ohm impedance values. Rears are 4 ohm and the sub is a 2 ohm

    I have 2F, 2R, 2 tweeters, & sub
    Here is a Pic of the RCA Inputs

    thanks

    it will certainly satisfy your needs, the only thing i dont know about is running different impedences on the front and rear channel, but i think that will be fine, it just means that the front will be louder than the rears....

    i'm almost posotive that the amount of wattage it is pushing to the sub will blow your stock sub if you arent careful, so watch the gain on that.

    I sometimes get confused about ohms, but I'll try anyway.

    Where did you hear that the front speakers were 2 ohms? Do you have separate tweets from the mids? If you run the mids and tweets in parallel, your amp will see a 4 ohm load, which is fine. I'm not sure about the sub, unless it's a dual voice coil, wired in parallel.

    Anyway, I'd love a six channel amp, but for 5.1 sound I'll need to crossover two channels on the amp indepentantly, which no amp I've seen is capable of.

    Good luck with your system.

    that sounds like cheap *** speakers...
    you may want to rip it all off. in my experience, I have found that the quality of the stock audio equipment is most of the times lacking beyond belief.

    for my part, I use Focal speakers and audison amps

    just a thought, wouldnt you need a line driver of some kind to raise the rca voltage to the amp(s)? I have no idea as to the specs of the output from a typical pc sound card though. However I know most decent head units put out about 4-5v, thats why i figured you would need a decent head unit with aux inputs.

    These are just questions i have been asking myself, regarding my ability to run a setup without a head unit
