    My Sub Blew Up Can Someone Fix it. Anybody

    My sub is now blown. This puzzels me though. It was audiobahn 4 ohm dvc AW1805. I had a power acoustik amp putting about 600-900 watts into it. It said it was a 2200 watt amp but who knows. It is a 4 ohm stable amp bridged so it wasn't being run at the right ohm with the amp. The sub was rated at 1200 watts rms. I know for a fact a power acoustik apache amp can't produce that kind of power. It wasn't even drawing enough power to brake a 60 amp fuse. It was bumping as loud as it usually goes(Really god **** loud) then it just went out and started making the sounds a blown sub makes. Here is a list of what I think could have been the problem. Please correct me if any of them wouldn't contribute to the sub blowing.

    1. Box is to small. about 2.5 cubes.
    2. Amp is to crappy.
    3. RCA wire. Still have the wire that I got out of a walmart kit.
    4. too small of speaker wire connected to the sub.(12 guage)
    5. Was running amp at wrong ohm
    6. Was just playing it to loud and it broke.

    Please give me your ideas.

    If anyone knows how to fix broken subs I wouldn't mind paying someone to fix it. Ill pay shipping both ways. Or would the best thing to do be to ship it back to audiobahn not under warranty.

    My guess is that your amp clipped so bad that your Audiobahn fried. I don't know if "fried" is the right term, but I do know that if your amp clips bad enough, you can destroy the speaker.

    Were you running the amp at 100% gain? My guess is that you were, because the sub's RMS is way higher than that of the amp.

    As for repairing it, good luck with whatever you do. Don't really have any suggestions.

    The amp was only at 75%. I haven't quite figured this thing out yet. I am going to use alot better components the next time.

    The gain was at 75% This was the level as to where at the volume it was at it still sounded clear. I could not notice any distortion until the sub went out completely. I have played the sub at this level ever since I installed it(2 months ago).

    Smaller boxes have better power handling capability

    Why does the amp affect the thermal limits of the voice coil?

    I run Walmart RCA's. This doens't make a lick of difference.

    You should never need larger than 12awg wire for speakers

    If your amplifier puts out it's maximum power at 4ohm bridged, this may be the case. Especially coupled with your 75% gain levels.

    Most likely. Gain too high, clipped signal, etc etc = melted/separated voice coil.




    Is this not a reasonable place to park?

    The sub has seen about 6 months of use prior to blowing. It wasn't until the last couple of weeks that I have been really testing all of the components. The cd player was at 85%, with the sub control at 100%. The overall bass was at 0db(mids.sub). The next time when I put it in I will be using alot better components(amp, rca's, speaker wire, box,). I will also be running the amp at the right ohm.
