I am so Pissed off right now...SomePleaseTellMeItsMyFaultAndiAmDoingSomethingWrong

If you have a short in your speaker wiring circuit, the electrical current will see a significantly lower resistance than it should, the amp runs harder than its designed to (like wiring it way below its minimum stable impedance), it gets hot and goes into protection mode.

Did you determine the short was in the wiring, or one of the speakers itself?

no, i just re-wired all four speakers yesterday and didn't feel like takin off those door panels, either way i am pretty sure its not the wiring from the any of the speakers. what i found was that a pair of my rca's had a short which i for the front speakers so i disconnected them and jus listen to the 6x9's @ the rear. the amp was still warm but it didn't shut off. O by the way how do i check for a good ground with a Dmm.my amp is under my passenger seat. and also if the battery negative (just asking) isn't properly ground will this cause my amp to overheat.

i want it to be the wiring bcuz i want to put back my alpine amp but that flippin amp gets hot too Da** quick...and it's runnin me hot fah real warrior.

Yes, a bad ground, on the amp's wire, or the connection at the batt itself, can make an amp overheat. Low voltage to the amp will send it into clipping easier than normal. Clipping increases the heat levels of the amplifier.

If you have the same symptoms with either amp hooked up, logic would say that the problem is in the wiring, not both amps.

ok. so thing to do would be to test both grounds at the batt & amp

Id check them, yes. Make sure you have any and all paint scraped away, have good contact, and no corrosion (I use contact grease). Also make sure you are grounded to the main body (or frame) of the vehicle.

my multimeter is reading negative whats up with that?....i tried testing the ground between battery negative and grounding point with multimeter set on resitance and it's giving me a huge negative number like -195.0 what does this mean? the lowest the multimeter could read at is 200
