    Thanks buddy,My battery looks as though its on its last legs,Could that be a factor in why my amps went loco?

  • SupraTTJames Sep 16, 2007

    Yeah It occurs whether it is running or not, Iv got a battery coming within the hour ill have that hooked up Iv also had a voltmeter installed into my dash,When the car lights are on and tha amp pulses the lights and all the other electrics go really dim

  • SupraTTJames Sep 16, 2007

    Hey buddy Iv had the battery fitted,the amp readings from the alternator seem to be above board, Even with the speakers disconnected the amp still continues to pulse and you can see a very small reading on the output dial,When this happens all the electrics inside the car flicker at the same time, I disconnected all the leads from the amplifier and there still a small reading on the voltmeter,Is that normal? I appreciate all your help

    Just in from work,hooked up the amp ground to the battery and the amp has now got a blue light, But what does this mean? Im a plumber so aint gotta clue Thanks again for all your efforts,Very much appreciated

  • SupraTTJames Sep 18, 2007

    Hi Is it safe for me to hook up the amp ground directly to the battery? Has the previous earth that was hooked up been the cause of the hastle?

  • SupraTTJames Sep 20, 2007

    Hi,Iv just finished hooking up my amp to the battery with 4 gauge wire, the problem still persists, but when I use very small speaker cable it fires up no problem.but the cable only lasts a few minutes before melting the plastic coating off,Can you help me please?

This indicates a possibility of a power supply issue, you may have to open up the unit and take voltage measurements to determine if the voltages are correct. In order to do this you will need a schematic diagram of the unit. Once you have the schematic you will be abor to tell which voltages are legitimate. I hope this helps

    You should also check the voltage regulator just in case. Does the problem occur when the vehicle is running?

  • Henry McKelvey
    Henry McKelvey Sep 16, 2007

    Ok when you get the new battery in test it under load. If the problem still occurs, which it should not, check the amperage from the alternator, if it is over specifications consider adding a new alterantor, battery, and voltage regulator for the audio amplifier, in addition check the ohmic rating of your speakers to make sure they are matching with the amplifier and are not creating a high current drain. I wish you well on this.

  • Henry McKelvey
    Henry McKelvey Sep 17, 2007

    It looks like you are drawing a lot of current. Keep the speakers connected and connect a ground wire from the battery terminal to the ground on the Amplifier. make it (The connection)one continous run with a large gauge wire.

  • Henry McKelvey
    Henry McKelvey Sep 18, 2007

    Yes it is safe as long as you tie it directly to the battery negative line terminal connector.

  • Henry McKelvey
    Henry McKelvey Sep 21, 2007

    Interesting What is the ohmic rating of your speakers and your sub?
    The reason I ask is because the smaller the wire the more resistance and the fact that you are burning the wire up means that it is dissipating heat. This could mean an impedance mismatch between the speakers and the amplifier. make sure the amplifier and the speakers (total impedance) match each other.

Well, sounds like you have an internal damage since it smokes, if it smokes as soon as it kicks on, and blowing the fuse right away, I would have it fixed. But my guess would be something with the ground that is making this happen, or some how your power is grounding on the amp. When ever smoke comes into play, thats never good any way at this point you gotta admitt that thiers internal damage.. blowing fuses can also be cause by over working your amp. along with the sub load at 1 ohm make sure your amp can do the same.. hope this was helpful in some way

Hooked up the amp, lights up, fans kick on and run fine, speakers hooked up proper, no sound? hooked up speakers to another amp and they work fine. Fuses are all good too. Thoughts?

could be bad rca cables or no output from the radio rca outputs. the sub control may be turned off on the radio (ive seen that alot at my work). if all that is fine, the amplifier may be bad. the rca cables may be plugged into the "out" section of the amp. gotta look at all the small obvious things first. good luck.

this is happening simply because your ground wire is either going bad, or it has a bad connection to your vehicle. check the spot where your ground wire connects to your car, and look for corrosion or a change of color in the wire. if you find anything like this, i would recommend replacing your entire ground wire. if the wire looks fine, just tighten your connection point, or move it all together.

Red light comes on but amp still tries to kick.

Try removing the caps out of the system. It sounds like they have gone out. What is happening is the caps start storing up the power like they are supposed to do but then they are being discharged as soon as they are full. Bypass the caps and that should correct your problem.

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up normally, the wiring and speakers need to be checked. If it still shuts down, the amp likely has blown output transistors.
