If it works in your friends car but not in yours, it sounds like you may have shorted or rca issues in your car. If you can run a different head unit and rca's in your car but the same amp and see if that works.
SOURCE: amp staying in protection mode
No, this amp is not a heavy power consumer- matter of fact it takes very little power to run.Maybe you should check the fuses on the amp to see if they are what is recommended.Also check your fuse kit to your amp- your fuse might not be big enough.If neither works take it back where u got it.
SOURCE: component speaker not working
The easiest thing to test is to try swapping the connections of the front component speakers at the amp connections. If the problem follows the speakers, the issue is probably with the speakers. I would triple check (again) the speaker wire connections. It's also possible the crossover for the driver side component speakers has an issue (thus why the tweeter worked for a while).
If the problem stays on the drivers side, the issue is probably with that channel on the amp. Triple check the RCA connections for that channel.
It's much easier to test other speakers on an amp channel versus trying to check it with a meter.
If the driver's door is "abused" often, my initial thought is the wiring at the speaker or the wiring in the speaker (to voice coil, within the crossover, etc) is the most likely culprit.

did you cut them and splice into them. Because instead splice them all together and it should all work. or if you have a multichannel amp just hook ur factories into the amp as well.
Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.
1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.
2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.
3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
system.
