    I have that wire connected. I am trying another amp... still the same problem though.

    i have connected that wire, still nothing.. I have connected another amp and still the same problem. I dont know what the problem is.

  • Seth Bernotaitis Apr 13, 2009

    The meter read 0 or a negative number where the wires to the subs hook up. Subs work great. i had them hooked up inside for a while just for fun.

  • Seth Bernotaitis Apr 13, 2009

    I still need help, do my problems seem to be caused by the amp malfunctioning/broken or does it sound more wiring problems? Again, thank you so much for your help.



    -is there a close to free service to get my amp exchanged or fixed?

    I also have a power acoustik 1000w amp i am trying, same problems but sent out a heart-beat-like sound to the subs when hooked up.

    Are you sure the subs are functional and connected properly?

    If you have access to a multimeter, with the subs disconnected, the resistance (OHMS) should be near zero. But for this amp, no less than 2 ohms for stereo mode, or four ohms for bridged mode.



    This measurement will look at DC resistance which is not really the same, so the best thing to do is make sure that you are not overloading the amp. remember that to connect speakers in parallel (positive to positive and negetive to negetive) actually reduces the resistance. In other words two woofers that are four ohms will be two ohms connected in parallel.



    Next switch your meter to AC volts. If it is not auto-ranging set it to the 200V range or similar based on what meter you do have. Turn the stereo to a moderate level and see if you can measure an ac voltage on the output of the amp.



    Let me know what you find out.

There is a wire that you must connect behind the radio deck that is blue, this is the remote wire, this goes from the wire to the amp and is what sends the signal that tells the subs to beat/make noise
you will want to run the wire from the amplifier to behind the radios wiring harness. this should fix the problem.
you also mite want to chek the settings on your deck and the volume settings on the amplifire

should do easily though you may need to employ the use of a cross over just incase something goes pop and burns you're car out when you park it after you've been hammering the subs.

Kicker l7 dvc 2 ohm wired to sony xplod xm1652z amplifier isnt pushing the sub


it is not the way how get most wattage from your amp. If it is rated to drive a 4-ohm load then it should be ok for a 4-ohm load. If it is rated for a 2-ohm load, then you should not be loading less than that impedance. I recommend a 4-ohm load.
Take note: it is the sound quality from the source that makes up all the total quality of your audio system. If you are overdriving the amps it will give distortion too.
There are many factors to consider when it comes to quality of a car sound system- speaker enclosure design, choice of speaker or driver, equalization, etc...
One more thing, try to get at least no voltage drops if you are wiring the subwoofer amp away from the car's battery.
hope this helps.

Sub power hadling capacity


Yes. If the rated power is 380W and the Max power is 1000W then it will handle it. Subs fry when clipping occurs. Clipping is when the amplifier is pushed past its capabilities and the output to the sub gets "dirty". The better quality the amp, the safer it will be on your speakers. It is also important to remember that the gain control on the amplifier is NOT a volume control to boot the sound, it is only to match the output from the headunit to the input handling of the amp. Cranking the gain up too much WILL CAUSE CLIPPING.
