    Hello everyone. I just installed a 125 watt amp and a 12 inch sub in a 96 Sebring. Everything worked fine for a moment and I was trying to set the sensitvity on the amp. When I did this I lost power to the amp due to a connection problem. I fixed the connection problem and got the amp to power back up but now the speaker is getting no signal. I am assuming that is the problem because I have power to the amp, the amp is getting the audio signal which is evident from the peak light. I dont understand what the problem could be. I have disconnected and reconnected the speaker wires and wiggled them around to check for a bad connection. I will appreciate any advice or help. Thanks.

    What do you mean that you lost power due to a connection problem??? Sure you didn't fry anything when you had the "connection problem"??

    Are you sure that your sub is not blown or just nonfunctioning??

    List model and specs of sub and amp if you could?

    By connection problem I mean that the amp wasnt getting power due to faulty connection spliced by me. I didnt have a crimper so I used pliers and they didnt do the job. Anyway, I suppose it is possible that the speaker was fried during this. I tired another speaker and it worked fine. What exactly could be fried in the speaker? The the connections inside the cab look fine.

    One of two things. The voice coil in the speaker fried or one of the wires from the voice coil to the speakers connectors broke due to a serious over excursion.

    Rule out the broken connection by simply looking at the leads, are they still connected. Voice coil can be chected with a Volt-Ohm-Meter. Simply check for continuity across the speaker leads.

    You didn't say wether the amp went into protect when the speaker was hooked up, if it did not the voice coil is not shorted, but it could still be open.

    I am not exactly sure what you mean by "went into protect". It sounds like a protection mode or something. There is no light that indicated this. The leads are all connected. Something that makes me wonder is that the back side of the input jack looks a little burnt. This could be from soldering guess. I will check with an ohm meter like you said. Thanks for the advice.

    Listing model and specs may help...if your amp doesn't even have a protect light than it sucks

    Either way, your speaker is bad.

    A good amp typically can go into protect for three reasons, thermal (its too hot) shorted outputs (including shorted speakers) or shorted power supply.
    But you said it worked with another speaker, so amp is OK and Speaker is bad.

    Nah...it was just a loose connection in the box. Now on to bigger problems. The system was working fine and there were 0 problems. Tonight, when I started the car something sparked under the hood on the passenger side(opposite side from battery) and the car wont start. It only sparks. I am thinking its the starter or altenator but what do I know. On the Sebring, the battery is hidden behind the driver side headlight. There is a positive post on the starter battery coming straight from the battery so I ran the amp from here. Its like a power distribution point and is labeled as a jump start access point or somthing. Im not sure if the wiring of the amp is related but I would like to know. If you can tell me anything I would really appreciate it. Thanks.
