    Sparking power cable

    Hi guys, I have in my car just a vide blackair 1400w sub and 2 6x9s that were both working absolutely fine for 6 months up until a few days ago. What I had done is ran one battery cable on a deprecate side of my car which went straight to the back and then when through a fused splitter and then into both amps. Only now both the fuses on the amps (one 30amp fuse in the sub and a 25amp fuse for the 6x9s) have blown but not affected any of the fuses on the system. So now I've pulled the 6x9s out and I only want to run the sub but whenever I touch the battery cable to the positive input it sparks like crazy and keeps blowing the fuse. So thinking it was a dodgy amp I tried with the 6x9 and it does it to that. Previous to connecting the 6x9s up I did only have my sub in and it work fine. What could cause this and how can I stop it? I'd appreciate some help.

    Thanks!

    Re: Sparking power cable

    Do you have a fuse on the power wire within 18" of the battery?

    Re: Sparking power cable

    What is the RMS rating on the amp and what size are the onboard fuses on the amp?

    Make sure there's no strands of your ground wire sticking out and hitting the positive terminal.

    Re: Sparking power cable

    What's the brand and model number, then? Are there even onboard fuses on the amp itself?

    Re: Sparking power cable

    check your connections. if its sparking that bad, you might've swapped the negative and positive cables from their respective terminal

    Re: Sparking power cable

    The amplifier could be shorted. It blows fuses with no speakers connected?

    Re: Sparking power cable

    Is it one good spark after disonnecting and then reconnecting? If it is you need to disconnect Batt ground pull fuses and this is the important one after all power is disconnected ground the pos terminal to discarge the internal capacitors inside the amp. If its a constant sparking you have bigger issues but it sounds like a stored charge in amps. I have had that before and wandered W.T.F. but its just what capacitors do. You can use a little 14 ga jumper to discharge tem I use a set of test leads with alligator clips.
