  • Sub problems?

    Posted by admin on October 8th, 2009 and filed under the perfect car audio system | 4 Comments »

    Im not too bright with car audio at all, I had my friend hook up my system, he’s really good at it as well. As long as I’ve known him his tunes have always sounded great in his car. Anyways, I had everything hooked up great and it was working fine for over a year, Finally my sub (which was really old, died out. I replaced it with a used rockford fosgate punch 12 inch which kicked perfect for metal. That worked for about 3 weeks when it suddenly just died out today. My Amp is a dual 460W and the rockford was a 400W, to me that looks like trouble. When this happen, my volume was fairly loud, and the speakers front and back started to distort very badly. When I shut it off, my speakers went back to normal but my sub is dead. I then replaced it with a junk sub for now because im scared it might blow again. I know I’m not giving you a lot to work with but is it just bad luck or is something amiss?

    you should look at what the amplifier power is look at the rms power not the max

    then get a sub that has the rms matched up to that of the amp

    maybe the gain is off balance ask your friend if he’s no help take it to a place where they install auto sound

      Does the sub have any noise at all coming from it? If not checking fuses is the first place to check. Also it could possibly be a disconnected ground or other wire. And don’t go above the rms of the sub with the amp.

      crap in crap out. The sub was used. You are banging your head, it just blew.
      Buy a quality sub new.

      two problems possible.

      1)Subs were crappy. Good sound costs more money. You should buy better subs

      2)Overpoverning – when you go loud with amp stronger than speaker, it is propably gonna blow – again – buy better, more powerfull speaker

      3) Amp can be broken down – limitating too early or sending "single way" voltage that can heat up your speaker voice coil without any sound. I guess it is not issue for now.
