|
danuguy Unregistered guest | well i have one sub hooked into each channel and my amp is a two channel so i guess it is wired in stereo but i dont know about the ohms. |
|

New member Username: Rowland336Post Number: 3 Registered: May-05 | If the protect light is on, check inline fuse size. & check to see if the fuse is blown on the amp. |
|
New member Username: Rowland336Post Number: 5 Registered: May-05 | How did the system work before the problem? Did you play it loud? Did you use it for a long time? was the amp hot? Need some more info |
|
danuguy Unregistered guest | i didn't think of the amp getting hott. like i sed i just had them hooked up yesterday and that was the first time they had been taken out of the box. my cd player's volume goes up to 62 and i had on about 50 for about 3 and a half to 4 hours not long after i had them installed. and they worked fine until this mornin. i checked the fuse on the amp and the one on the power cable and the don't look blown. |

|
danuguy Unregistered guest | there's not an on or off switch on the amp. there's only a light that says power above it and a light that says protct above it. i dont know if that matters but i'll go try it. |
|
danuguy Unregistered guest | i just tried it and nuthin happened.the protect light is still on and the power light is not coming on. |

Bronze Member Username: Fastbastard1977Lousiville, Ky Usa Post Number: 95 Registered: May-05 | are you getting power to the amp.if you can take a piece of wire and touch it to the powerside of the amp then touch then touch te other side to some were or your car thats bare metal and see if it sparks. but do it fastso the wire dont get hot and blow the fuse\ |

Silver Member Username: ByrumjrPost Number: 223 Registered: Jan-05 | Pleas don't do that unless you want to buy a new amp. If the protect light is on, you have power to you amp. If you had your head unit at 50 you might have clipped you subs. Unhook all sub wires and the light should go off. If it does not go out then you may have burden the output in the amp up. You can also hook the sub up to something else and see if the work. But the best bet is take it back. What size fuse is in the amp? |

Silver Member Username: AraknidBOCA , FL U.S. Post Number: 569 Registered: Nov-04 | Yeah what size is the fuse on the amp or if theres more then one what is there total value added together? and what is the size of the fuse on the the power wire under the hood? Or where ever you have it. |
|
danuguy Unregistered guest | the one that is under the hood is a 20 amp fuse. the one on the amp is a 15 amp fuse. |
