What is wrong with my system?

[pbmulligan]

I have a new JVC typical head unit, and 4 rockford P163's in my 2005 toyota matrix. They were all recently installed, the head unit by best buy, and the fours speakers by me. Recently, I noticed that either the left pair of speakers, or the right pairs, will crackle and sound almost like the are blown. But maybe half a day later or 30 minutes later, they will go back to normal. Can anyone diagnose this problem?

the speakers are run off the HU?

Yes, at the moment all four run off of the JVC head unit

Make sure the positive and negative connections aren't touching each other. My friend's little brother installed his speakers and were doing the same thing... took off one of the speakers and immediately saw + and - wires touching each other.
