I could probably fry an egg on that thing...the thermal protection kicks in probably 5 minutes after it starts hitting. I do have the it mounted on the back of my sub box due to the fact i have no room to put it horizontal. Is there any way i could cool it down so it wont shut off so much??? I have heard of people putting new fans in it. How about mounting it sideways instead of up and down?? HELP? thanks |

Bronze Member Username: SpyderEglin AFB, Florida USA Post Number: 35 Registered: Jun-05 | actually if they are 2 oh dvc subs you can't wire em to a 2 ohm load.....it's either a 1ohm or 4ohm load......check your wiring man..... you have 2 or just one sub? cuz if you series the subs then run them paralel bridged on that amp you should see a 2 ohm load then....just double check and make sure they are setup that way. |

allende5 Unregistered guest | Yeah, it sounds like you wired two 2ohm subs parrallel all the way through. If you were wired in series all the way through, you'd have an 8ohm load (incorrect) If you were wired in series then parrallel, you'd have a 2ohm load. (OK) If you were wired parrallel, then series, you'd still have a 2ohm load (OK) However if you're wired parrallel all the way through, you're pushing a 0.5ohm load (Very Bad) This would explain the very quick overheat problem. You want to series only the DVC on each sub. Then wire the two together in parrallel. Make sure you're wired (+) to (-) to (+) to (-) on each individual sub. Then wire the two subs together ( + + ) to ( - - ). |

allende5 Unregistered guest | I'm from California too. It's been very hot where I am lately (90-100's). My car with the system in it is down right now, so I haven't been using it in this heat. What kind of car do you have and where to you have your amps mounted? It's very possible that it's just too darn hot and they're simply not getting any ventillation. |

An amp overheating within 5 mins is a sure sign of incorrectly set gain/level or most likely, exceeding the minimum ohm requirement. |
