Sony amp going into protection mode
|
Bronze Member Username: Gibson5469Post Number: 50 Registered: Jul-05 | I got this 600w (max) 4 channel sony amp from a friend for free (it's brand new). Im bridging the rear channel to run my Kicker Comp (single coil 4ohm). The gain is set less than half way and the amp is going into protection mode?? I've used a multimeter on the ground and power wire at the amp, got a clean 13v (same as measured at the battery) Any ideas? |

Bronze Member Username: Gibson5469Post Number: 54 Registered: Jul-05 | sorry about the link. well i figured out the problem, my box was way too small for the sub. i mounted it basket out style and it works 100% fine.  |

Bronze Member Username: Gibson5469Post Number: 55 Registered: Jul-05 | ran it for over an hour like this (with no problems at all) amp is 2ohm stable (so 4ohm's is the minimum for a bridged channel, which the sub is) http://img486.imageshack.us/img486/6181/p1000510dz1le3.jpg |

Bronze Member Username: JeromebakerPost Number: 59 Registered: Dec-05 | "box too small for the sub" doesn't make an amp go into protect mode. Sony amps are basically stable to no less than 4 ohms, they say 2 but they'll shut down at that. It should theoretically work bridged at 2 ohms but don't bet money on it long term. Garbage amp, but free's free. |

Bronze Member Username: Gibson5469Post Number: 62 Registered: Jul-05 | would the basket of the sub being less than 0.5 of an inch from the back wall of the box cause this? I mean, nothing else was changed besides flipping the sub. |

Bronze Member Username: Gibson5469Post Number: 63 Registered: Jul-05 | idk then. nothing else was changed. it's still running off of the bridged rear channel. |

Bronze Member Username: JeromebakerPost Number: 63 Registered: Dec-05 | Then you're stoked. Wait'll you hear how good your sub sounds on a real amp. Quite a difference. |
