Re: WHEN I HOOK UP THE AMP
Check your speaker connections and the try to power the unit on again. I fear that you may have damaged the power amplifier MOSFETs on the output stage. This is what this sounds like. I would first try to see if audio is going into the unit by using an oscilloscope and taking a reading at the input of the amplifier. If audio is preset I would take the unit to a shop since there are no user serviceable parts inside of this device. Look for a shop that will give you a free estimate. I do feel that you have internal damage to that device.

Batteries are holding back the 21st century. I have the older model of this and my battery went bad very fast. Now I have to keep it plugged in and not just any usb port will work it has to be a usb power supply of at least 2 amps. I keep mine in a 2100mA usb source.
Sounds to me like the amp is going into protection mode. Try placing one sub on the amp with very little gain. One of the biggest reason why this happens is because the subwoofers are wired wrong. What is the brand and model number for your amp?
The LED should be red. If you are not getting power to the sub, make sure the speakers are connected properly to the amp. Also make sure that the gain control is turned up. If it is all the way down, you will not hear anything from the sub(s). If none of that works, it is possible that you have a blown sub. If you smell a burnt smell near the speaker magnet, there is damage to the voice coil in the sub.
Try disconecting all speakers from the amp, turn it on after and if it stays on red it sounds like it had kicked the bucket. if it stays green start from their and check all of your wires for shorts (speaker wires) again. hope this helps...
that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad
Unplug the inputs and outputs from the amp (be sure to mark the wires so you can hook them back up), leaving only the ground, +12, and remote wire hooked up. Now, turn it on. If the amp light goes red, the amp is broken. If it goes green, turn if off, plug in the speakers, then turn it on. if it's red, its a speaker problem, if green, do the same with the inputs, and you'll have your answer.
