    Re: Car amplifier at home (diy)

    I can't help with recommendations but I'm sure glad I'm not you neighbor!

    What is a "adc convert 3000 watts" and asking what is available in your home area means nothing to a World Wide forum. We have no idea which stores or suppliers are in your locality or indeed where you actually are.

    PLEASE - no friends requests or private emails, I simply don't have time to reply to them all.
    It's better to share your questions and answers on Edaboard so we can all benefit from each others experiences.

    Re: Car amplifier at home (diy)

    On the other forum I said that the 12" woofer has a resonant frequency too high to be a sub-woofer and the amplifier has an output of maybe 300W into each speaker's two paralleled coils.
    The ebay no-name-brand speaker and amplifier junk are missing many detailed spec's which are probably exaggerated.
    I agree that you need that extreme amount of power because in your car it deafened you.
