Re: car speaker

You can use a 9 volt battery to test wire polarity
. Hook up the + wire of the speaker to the + terminal of the battery and the - speaker to the - battery terminal. If the speaker moved UP or OUT then the wiring is correct.
If it moved IN or DOWN then the + and - wires are backwards on the speaker.

Also if you have two or more speakers hooked together test all the same way while they are hooked to each other. ALL of the speakers need to move in the same direction at the same time.

Clipping causes more speaker damage than anything. "Dirty Power" can happen in good quality amps too. The gain control is to match the voltage between the headunit and the amp. It is NOT a volume or boost knob. If you overdrive the first stage of the amp and then clip it damage will occur to the amp and speakers at some point.

Hope this helps.

Subwoofer in truck is getting interference

Hi whit kendrick

Probably your amplifier is defective, an amplifier that produce an audio that drives your speaker. Try to open your amplifier box and if you notice that a component attached on heatsink, thats an amplifier.

No sound from speakers has a fuse blown

If fuse has been blown means power capacity of the subwoofers exceeded the actual power transmitted.Subwoofers capacity cant hold on to the actual power transmitted.If you replace a new fuse check first if internal circuit was not damaged .When a fuse blown out its an indication that something wrong happened within the circuit.Check first subwoofer line if there was short circuit using a tester.Select OHMS mode and try to check both lines.If no movement it means you have it check to a service technician to fix.

Drivers side speaker don`t work no sound it did at 1 time!! what could be the problem and how to solve

Check the continuity of the speakers using a tester.. set it to 10K Ohms. If the tester moves then you have a good speaker but if it doesn't move, then you have to replace your speaker.

You might want to check the speaker volume balance first... ^_^
