I dont know what your using for a power source, but the problem maybe that your powersource does not have a high enough current to turn the amp on. Most likely that is not the case.
If need be carry the amp out to your car, open the hood and try using the car battery for a better power source.
If your having a problem with the amp, the best way to eliminate possibilites is to try and power the amp up with just the positive, negative, and remote connections. Leave the speaker and rca cords disconnected.
Just a side not too, you should always connect the amps ground before the positive and remote. You can easily mess up an amp if not fry it by powering it up with no ground. Im saying this because you said "as soon as i touch the ground it goes into protect". When the power and remote are hooked up, and you have whatever you are using for a power source or even a car on with no ground, the amp will search for a ground and try to ground through whatever it can, if it fines no source for a ground it could fry or damage the amp beyond use.
The SPL amps are pretty much garbage and low grade amps (worse then things like jensen, power acoustik) and rate along the lines of boss, pyrmid, pyle, etc. The build quality is not the greatest so anything little could jepordize the amps ability to function.
