New speakers get distorted after awhile.

So in the shop at work, I've got a car stereo in a cabinet to keep us entertained while we pull wrenches. Just bought 4 new Kenwood 6x9s 3ways to replace the old junk speakers we had there. Built some plywood boxes to put them in. They are a little louder and sound a lot nicer than before, but after awhile they get to be a bit distorted. I am trying to figure out why. The stereo is always turned up fairly high because our bays are big. Head unit is a Pioneer powered by a 12v power supply plugged into 120v. The back of the unit gets too hot to touch. Some possibilities I have come up with are:
1- the head unit cannot push these speakers properly and is overheating?
2- the 12v power supply is not providing enough power for this.
Anybody have any ideas? There is also an amp and 2 12" subs on it, but they are powered by a 1500cca Cat battery, if that matters.

Your asking that head unit to push too much power for too long. They really should run off an appropriate amp.

That's what I was thinking too. Going to pick up an amp on days off and try that.

So an update. Picked up an amp for a good price, and installed it. Big difference. System rocks now. Thanks for the help.
