the best thing to do is get in touch with amazon,and see what they can do about it,if you try to fix the problem yourself it will invalidate the garantee!
either ur ohm load is way off ur pos n neg might be touchin or more than likely u blew u sub is it scratchy when u push in the middle of the cone ? does it push in at all?
Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.
Ok it sounds to me that your remote wire is not hooked up right casue if you trun your car off then your amp should power down an when you trun your car on it should power up
Unfortunately I think you need to get it repaired or replaced .When a protection light will not turn off it is generally caused by an internal short and needs one or more replacement parts for it to come alive again.

There are a couple of tests you can perform. I'd first recommend checking the shield ground. You'll need an ohm meter. The details can be found on the following page.
You can also test the output with the multimeter. Set the multimeter to AC volts. If it's not an auto-ranging meter, set it to a voltage range of ~2v AC. Disconnect the RCA cables from the head unit. Touch one meter probe to the outer ring of the head unit's RCA jack. Touch the other probe to the metal contact in the center of the RCA jack. With the head unit near full volume and a clean signal source, you should read at least one volt on musical peaks. If you have a bass disc or a test tone disc (~60hz sine wave), use those.
hi, your amp seems to be getting power but the cables might be wrong so it's not getting enough power. the light on the amp should be green if everything is going well.
are you sure the cables are suitable for your amp?
