I know from experiance with my friends 1000watt alpine that it can kill a running engine if idling. You have to make sure you have a solid charging system and battery before running that type of power. That is the price you pay, you have to make sure everything is up to snuff if you want the big numbers and 4ga won't cut it.
    4 gauge is definatly enough in this situation. Theres nothing wrong with looking at the fuses to see how much something could draw, its not going to tell you how much something will draw but its going to give you a maximum.

    One point, have you upgraded the car shell ground to the battery negative, sometimes you can run a 4Ga ground to a good point on the body, but the body is only connected via old 10 or 12 guage to the battery negative

    Could it possibly be that the Cap is wired up backwards. Ya know positive on negative and visa versa? But i would think the cap and/or the amp wouldnt even power on then.
    Thats the problem right there, strange nobody reacted to this.

    Thanks a lot everybody who tried to help. Beleive it or not i tried almost every suggestion and nothing would get this thing to work. So i had to take it to a place that fixes and tests amps in my area and spend 50 bucks to have it tested and another 175 to get it repaired since its out of warranty. Sucks a phat one but even with the added cost i paid well under retail.

    Thanks again for all the help.

    Most amps will now go into protect mode if you do not have your ohms correct...make sure that this is the case...the other thing is that you could have a bad speaker somewhere...try them all out at a very low gain individualy and see if that works.

    Your amp going into protect has nothing to do with power connections. So stop looking there.

    The protect circut protects the speaker outputs. You are having issues on the speaker end.

    This is typically due to a speaker / amp mismatch. or a blown sub.
    You need to know what ohm load your sub runs at. Single 1, 2, or 4 ohms.
    Dual 1, 2, or 4 ohms.

    Then you need to know what ohm load the amp is stable at. Most amps say if they are 2 ohm stable will go into protect if connected to a sub wired at 1 ohm. Competition amps are better at handleing reduced output loads but even there many will go into protect if pushed hard enough.

    My gut feeling is that your 6 channel is no more than 2 ohm stable and your sub is wired to a 1 ohm load. Hence the amp goes into protect. You use a ohm meter and measure across your speaker leads while disconnect from the amp. THis will verify things.

    Ok, did you even do a search before asking this question? cause it could be about ANYTHING....

    How could we know what's wrong without ANY kind of info.....
