Bronze Member Username: AkamigsPost Number: 18 Registered: Apr-06 | the subs are svc. the amp is mounted between the box and the back seat. i drive with the back seat down but i dont think thats enough air to cool the amp. |

Silver Member Username: CtmikeCt. Post Number: 461 Registered: Feb-06 | if there svc thats your problem (i think). can't run 2 svc 4ohm subs at 4ohm load. http://www.crutchfieldadvisor.com/learningcenter/car/subwoofers_wiring.html?subs =2&impedance=SVC4 probably why your amps running hot and shutting off, going into protection. |

If the amp gets hot and shuts down, then most of the time, it's caused by that control set incorrectly. Also, it could be that your sub(s) are not really 4ohms. Some are 3.5ohms. That will also cause the amp to overheat. You can never assume based on a sticker on a sub, especially from the cheaper brands. |
