[QUOTE="cgrier, post: 2502134, member: 572596"] Ok i recently upgraded from a alpine head unit to a pioneer avic-d2 system. I've never had a problem with my sub but lately the subwoofer seems to go in and out and sometimes when the bass hits it makes a weak rattling sound instead of normal sounding bass. It seems to only happen when the volume is low and goes away as soon as i turn it up. It also seems to happen more when i just turn the car on and its not warmed up. As far as i can see the wiring is not loose or anything and i cant figure it out. I messed with all the settings on the HU and nothing seems to work. Anyone have a clue? Here is what i have... Pioneer Avic-d2 Alpine MRD-M1005 Alpine Type R 15. It runs at 4ohms at 500 watts rms. Wiring is 4 gauge. [/QUOTE]
