Does anyone know what would cause a brand new sub to constantly pulsate (makes a "wump wump wump wump" sound, with 2-3 wumps per second, and the cone is traveling at least an inch outward)? The only things that will stop it are WOT acceleration from a dead start, and some times cranking the volume. It's a Rockford Fosgate 10" Punch running off of a brand new kenwood head unit, fully new wiring kit (RCAs with a 8 gauge hot lead off of the battery), and an older but reliable amp. I'm posting because I did the install in a friend's jeep and feel bad that it isn't right. I've done about 6 stereo system installs, but this problem is over my head. Any ideas? If you need more specifics, let me know...
