depends on what the RMS is for the subs because although the subs are 1200 watts, there is a minumim standard you have to follow. If you don't atleast run the lowest wattage thru them, then you will most definately damage the speakers....you should also be aware of the fact that your "600w Pioneer-4 channel amp doesn't even push a true 600 watts... Your best bet is to upgrade ur amp, or add an additional amp to your set-up. And you really need to pay close att to over or under running your power to your stereo system because you'll burn out ur altenator rather quickly. Use proper wattage , and you should also look into getting a power-cell which lessens the chances of destroying your altenator and helps to ensure that your stereo system sounds to its full potential.....

you can buy one at the pioneer website in accessories parts. but if you are talking about a wiring harness that wires directly into the existing wiring harness for the car then you can get one of those at any local car audio shop. or walmart sells them cheap.

Here's a link to the installation guide for your unit different model but the wiring is still the same. May have wires your don't but the basic wiring will be the same.
It is in PDF format so you will need Adobe to view it. You can get it for free at www.adobe.com

The frame of the vehicle is ground, the metal enclosure of the radio is ground also. If you have a ground wire coming out of the radio and you don't see the ground wire from the vehicle, then attached it to the cars frame.

Check your connections to your speakers and amp and look for loose wires touching metal. I believe your stereo is fine, this has something to do with your speakers and the speaker wire
