    Need advice on amps

    My current amp, an old Sony will currently only power one of my 2 subs when bridged. They're Rockford fosgate 10" punch subs. Both subs work, however only one of the 2 terminals work on the amp. That said, I'm not too knowledgable on sound systems and would like help in figuring out a new amp to get. Preferably as inexpensive as possible. I don't need to shatter any windows or blow out eardrums, I just need something that will power my 2 subs and last me.

    Thanks,
    Dan

    Re: Need advice on amps

    are there two pairs of positive and negative terminals on the amp? You can actually wire your subs in a way that it would still work if only one pair of the pos and negative are still working.

    Re: Need advice on amps

    Gary, the subs are Rockford Punch subs. 4 Ohm DVC, unsure on individual wattage.


    Jeff, The amp is a sony XM-3040F, its ancient, but its what I have at the moment. I'm hoping to upgrade to something less antiquated and more functional. <$80 hopefully. And you are correct, it does have more than one pos/ neg terminal. just the one works, however. That said, how would I go about getting both to work with the current amp and would it be harmful to the setup?

    Thanks,
    -Dan

    Re: Need advice on amps

    If they're DVC 4 ohm you can wire each sub to 8 ohms (voice coils in series) then wire the 2 subs in parallel for a final impedence of 4 ohms.

    Forgive my lack of knowledge, but I had to have my brother practically soon feed me with the installation. So how would I go about doing that?
