Hi all, i've got an issue with my kicker sub... It seems that at random times, usually happening quite often now the bass will be pumping normally as it does then dims a fair bit as if i just turned the bass down on the sub (but not like there is no bass at all, there still is some bass).. then it will go back to normal again. Like i mentioned, vey random times this will happen and the dimming does not really have an exact time that it lasts it may be for only 30 seconds of a song or 2 minutes. It's running off a two channel, the head unit is Pioneer FH-P6050UB, i've played around with the high pass filter for the speakers and sub, both are on 80Hz. What could possibly be the problem??
