    Hello all,

    with two 10" 100watt subs... I have a Deicated PS for the amp...The amp powers up and powers the subs...but when i hook up the RCA cords to my computer it get no sound....But....another thing is....even before i plug the rca's in My sub hums is that bad? or not healthy? becuase one hums one doesnt. So what im asking is...WTH Do i do know?

    Thanks,
    Aaron

    if your sub hums it's an indication for a ground loop. Meaning your install is faulty. That or your amplifier is either on it's way out or it's not of a very high quality. Also, if you have the gain on your amp turned up it can cause this noise as well.

    If one sub hums and the other doesn't i'd check the wiring on the sub that hums. Make sure you have everything wired correctly.

    Do you get sound if you plug in a set of head phones to the audio out jack on the mobo?

    What amp, what subs, and how do you have them wired?

    I have the wires connected straight the speaker cuz i thought it may have been crappy wireing....And it still does it...And yes sound does come out of my sound card.

    And My Amp is a DUB Mag Audio DUB2502 2-Channel Class A/B Amplifier
    Link to it
    the subs are Amercian pro 10" 4 ohms 100watts

    and i have them wired corect i think...lol...i dont know how to say how i have it wired...Cuz the neg is with the pos with pos etc.

    Can you clarify this please?

    you have what wires connected straight to the speaker? Can you take a picture of the wire connections at the speakers?

    Those are very low quality components. I just want to warn you that you will have some noise in your system with these components, ESPECIALLY if you haven't taken the time to make sure your grounds are secure and solid.

    and i have them wired corect i think...lol...i dont know how to say how i have it wired...Cuz the neg is with the pos with pos etc.
    So you are saying then that you have one sub wired to one channel on the amp and the other sub wired to the other channel on the amp? If you swap the subs (wire the other sub to the other channel and visa versa) does the hum follow the sub or does it stay on that channel?

    btw- this review of that amplifier is a new classic:

    this amp did bump both of my ten inch subs until it overheated and started smoking but besides that this amplifier does bump compared to all them other amps ive bought before....
    I'm nearly peeing myself from laughing so hard...lol

    if it's the channel humming that means it's the amplifier and not the speaker it's self. I asked to help narrow down the source of the problem.

    Do you have the gains turned all the way up? do you have it faded from one side to the other?

    Please explain to me how you have your ground secure. Where is it? What gauge wire is it? What gauge wire is hte power wire? Where is the bolt you are using to ground the amp?
