Ok..I have 2 Pioneer Champion series 12's and a Pioneer Stage 4 PRS-D1200M amp,a Kenwood - KIV-BT901 headunit. The problem is..When I plugged my subs wires into the amp with volume down on the headunit.My subs start moving in and out as if very low bass is being played.I guess you call it excursion. Then they'll hum as is very high bass is being played. I've Tried 3 different amps. I used my old Sony xplode headunit to see if the kenwood headunit was the problem but it still does it.I've used a different sub that I got laying around too. I tried different RCA jacks too. Anyone knows what could be the problem. 2001 mitsubishi galant
