Hi...
#1 Is the subwoofer connected? #2 Try connecting another speaker to see if your original sun is bad If the trouble is still there either you have a power supply failure or one amplifier section that has failed ( needs parts)

I have an Aiwa cx-na707 stereo and need to know how to hook up the super woofers. Are they amplified or do they need external amplification?


I can't find a manual or a good picture but a clue to that would be if the 'super'-woofers have internal amplifiers as evidenced by their own power cords, making them 'active' or if they just have speaker wire conencting them to the main unit (most likely at this level of product).

I have two sub woofer and when turned on to 16 to 18 volume the amp gets off...


its probably one of the below
going on protect mode as the amp cannot handle power
going on protect as voltage is dropping too low (upgrade wiring kit)
check if your amp is 2 ohm stable (if you have it paralelle on the same chanell)

Subs will pound then suddenly stop, when you turn the ignition back they will sometimes start to pound.


What you must do is check the amplifier when they stop playing.

Check wether the amplifier is not in protection.

If it is feel how hot the amplifier is. You may have the subs wired incorrectly to the amplifier.

Check the thickness of your power cabling. If it is not thick enough then the amplifier will also go into protection.

IYou can also try disconnecting 1 of the woofers to see if maybe you dont have a faulty sub.

When I hook up my amp the prot. lite comes on. Whats the deal?


IT MIGHT BE A BAD WOOFER, AMP.. WHAT YOU CAN DO IS PLUG THE AMP UP WITH NO WOOFER AND THEN SEE WHAT HAPPENS AND THAN PLUG THE WOOFER UP AND IF AMP GOES TO PROTECT THEN ITS WOOFER IS BAD AND MAYBE ITS VOICE COIL

Visonik amp problem... amp goes in and out of protection


Check for intermittent shorts on the speaker leads.

Turn down the volume control on your head unit while operating the amp, you could be over driving the amp.

Remove Speaker leads and reset the amplifier. IF the protection LED still comes on amplifier is faulty.

Below is the link to put in a help request with the manufacture for repair.

Turns off if sound level is increased


there is a protection circuit kicking in.

First thing to check.....Verifiy that all speaker lines are in correct polarity.

+ and gold or writing/stripe on cable.

Check this all the way around and if the sub is a line in sub,, check that also.

You really should just unplug them all and start one by one.

If you cannot get to the wires or its too hard to access,

hold your hand 1/8 of an inch from the woofers. they should be kicking out, not pulling in.

Could also be a blown woofer somewhere in the system.


Hope that helps!

Subwoofer acting wierd


If you turn the power off and restart, the most logical answer i know of is your amplifier is going bad.
I am not sure of the model and brand of your amplifier, but there should be a protection light on the amplifier somewhere that will most likely be on, caused by overloading the amplifier.

You will most likely have to replace the amplifier, or check with the manufacturer to find out if they can repair it or help to further diagnose the problem.

XM-552HX ofside led turn yellow


You may have an issue with the impedence of the woofers causing the unit to go into protection mode. Make sure that the woofers are no lower than 2 ohms at the amp. This can be done with a voltmeter to check. You are better off running the woofers at 4 ohms if possible. If you disconnect the speaker wire from the amp, does the yellow light still come on? If so, then there may be a problem with the amp.

My kicker amp turns off


It sounds like you may have the load impedance too low. How many voice coils per woofer? How many ohms is each coil? If you have DVC woofers, are the coils for each woofer wired in series or parallel? Are the speakers wired in series or parallel. Let me know if you need me to clarify anything.
