    Post Subwoofer keeps cutting out....

    Ok, so I just signed up on this here thread, and did my fair share of searching for what I'm looking for and couldn't find anything that related to it. So, considering that I don't really know much about car audio, I'm going to do my best to explain my scenario.

    I drive a 2004 Mazda 3S.

    What I have installed is:

    1) Sony F5700
    2) AUX Wires coming from head unit to connect iPod.
    3) One 12" Rockford Fosgate Punch Sub
    4) One Rockford Fosgate Punch AMP (Not quite sure the wattage, used to be my brothers. Used to be able to support two 12"'s in his car so I'm assuming it's around 1000+ watts)
    5) American Legacy 2.0 Digital Power Capacitor

    (The sub, AMP, and Capacitor were all my brothers, so I don't know much about them)
    (I also had all this installed at a professional place.)


    My scenario
    When driving around, say for a short distance, like a 10 minute drive, the sub and everything works fine. Knocks nice and hard, sounds excellent. But say when I'm driving for a longer distance, say around 20-30 minute nonstop drive with the stereo on the whole time bumping, the subs will begin to cut off. The bass is still fed to my car door speakers, but the subs just cut out. No bass whatsoever going to the subs. I then have to turn the head unit off and turn it back on and the subs come back on. It bumps for a few minutes and cuts out again. Repeat this process.

    I was thinking it had to do something with the capacitor and having it cut the feed to my subwoofer. Even when I put the bass on real low, HPF and LPF to +125 and such, it still acts up and cuts out the bass after a while. The number reading on my capacitor is generally jumping around from 13-14.5 . . . I don't know what the meaning of it is but, that's what it is. Maybe I need to set it higher somehow? I checked the wires several times, and nothing is loose. It's pretty solid on that half..........

    Anyone have any possible solutions or ideas what it might be? I just thought I'd rather come on here first and ask around before I take it to a car audio place and have them rape me of my money just for looking at it.

    Any help is appreciated. And if this has been posted, please don't bash.

    Thanks.

    This forum is dedicated to CarPCs and installing them in your car.

    The car audio forum is dedicated to integrating your car audio system with your CarPC.

    For specific questions related to car audio equipment systems that do not include CarPCs, I would recomend checking out car audio specific forums:

    http://www.elitecaraudio.com
    http://www.carsound.com
    http://www.caraudioforum.com
    http://forum.sounddomain.com
    http://www.realcaraudio.com

    http://www.termpro.com
    http://www.the12volt.com
    http://www.talkaudio.co.uk
    http://www.caraudiosecurity.com
    et. al.

    There is a chance that someone on here might have an answer for you, I would just hate for you to wait around for it when I know you could get an answer much quicker on a dedicated forum.

    Good luck.

    Have you looked in the FAQ yet?
    How about the Wiki?

    Darque is right.

    But I feel genreous being the holiday season.

    Chances are your amp is overheating and probably going into protect mode. You are pushing it too hard. Does your amp have a protection light?

    1) Load of subs (Impedance rating is too low for the amp to handle it.)
    2) Your gains are not adjusted properly and you are working your amp way too hard.
    3) Your crossover is set too high @ 125Hz. Shoot for nothing more than 80Hz or even 60Hz. This will reduce the strain on your amp.

    There is so much that it could be you should take it back to whoever installed it and have them check it out. This is all I am going to give you, otherwise it's going to turn into car stereo 101 class.

    One more as a stocking stuffer...

    Make sure the power wiring is the correct wire size for the current draw of your amp. If it's melting or getting discolored or is too hot to touch by the battery after running it really hard you have a problem.

    Ah, alright. Well, thanks to the moderator for at least posting it, even though it's the wrong forum. & Thanks to those who replied. I shall seek help on the other forums, unless anyone else has a solution.

    I will check the amp out and such when I get a chance (The gains and stuff).
