    Well I have two 15" subs and a 2000 watt amp and a 5 Fr. Cap. So here is the problem I was riding around lessoning to the radio and it work great well when home turned it off. So I come out the next day and get in the truck. Turn on the radio and now if I turn it up to past 10 on the volume the amp starts jumping between Protect and ready but if I turn it back down I will work. All the other speaker in the front work fine. Any help is greatly needed. Thanks. /forums/images/graemlins/1zhelp.gif

    what is the amp? what are the subs?

    sounds like you have loose wire.

    Don't laugh. /forums/images/graemlins/wink.gif The amp is a Boss Klash and the subs are Rockford Fosgate HX2 2215's. I am going to check all the wires tonight.

    Sounds like:

    1. A short
    2. Blown Voice Coil
    3. Unnaturally low ohm load due to wiring config


    Pull the speaker wires off the amp and measure each sub...see if either one shows 0 ohms.... that would be bad.

    If each speaker is on it's own channel, there's not much chance that the ohm load is too low for the amp... usually that stuff only happens when "paralleling" a bunch of speakers together and hanging them off a single amp channel.

    Bad amp? You get what you pay for....and based on your comments, I think you already know that amp might be "a suspect"..... /forums/images/graemlins/blush.gif

    what is the best way to check for a blown Voice coil?

    I have used a few Boss amps and two have worked good. The only reason I have not bought a "good" amp is because I have not found a permanent setup yet.

    Well the "smell" might be a giveaway....or maybe some mechanical binding if you push on the cone. But really it's just the ohmmeter that's going to tell you what you need to know.

    Stuff around 4 ohms is probably normal.....but almost ZERO or something very HIGH resistance wise is not normal.

    Also check for any small wire strands that may have splintered off the speaker wire that could possibly be shorting across the terminals....either at the amp, or speaker.....sometimes little stuff like that is easy to forget and it will seem "intermittent" with vibration, etc.

    Re: Can you help me troubleshoot?

    Ok well it was the amp I replaced it with a different amp and now it works. Now one channel is a little intermittent I think it is this amp. The channel being intermittent is why I replaced it. I tested both speaker and the ohms were at 2 ohms. That is the way I have them wired.

    So in conclusion I guess I need to replace the amp. Thanks for your help. /forums/images/graemlins/thumb.gif
