The first thing to check is the 'peak-on' (switch wire) from the head unit to the amp, normally a Blue wire. If it has 12v when stereo is on the stereo is ok and it is an amp fault but if there isn't 12v then it will be the head unit.

XA10002 dual channell amp pushing a single 12 inch JL Audio sub and continues to go into protection mode. All setting are turned to the lowest possible and remote wire, power wire, and ground wire are all...


Make sure you are wiring the sub to the correct ohm's. Some amps have a protective feature that will send them into protect mode if they do not since the right ohm load. If the sub is wired correctly double check your ground wire on the amplifier, and if that if also fine then your amp will need serviced.

The light is red and no bass is coming out of my subs


The Amp Is Most Likely In Protection Mode... 2 Ways To Figure Out Whats Wrong With it Is Check Every Single Wire And Make Sure That Every thing Is Hooked Up Correct And There Are No Bad Connections With Ur Remote Wire, Ground Wire, And Battery 12v Wire, Rca Cables As Well. If Every Thing Checks Out Good Then Try Checking The Fuses And Make Sure u Are Using The Correct Fuses That Are Good For That Amp. If U try These 2 Things And You No Your Subs Are Hooked Up Correctly Then The Worst Is Probably There. I Had The Pioneer 7200 Amp And It was A Blown Amp And The Red Light was Constantly On. No Sound No Nothing. If U Try Those Steps And it Still Does Not Work Then Most likely Your Amplifier Is Toast. Hope This Helps :-)

Can not find a way to turn on my subs


Well 3 things will stop your subs from turning on. Your remote wire is not hooked up (it turns the stereo on when the key is turned). Your fuse is blown under the hood in your inline power wire. Or your amplifier is not grounded.

1000 w sony xplode works at low volume then red lights at volume5


Most likely one of your subs are blown, or the Ohm's are too low for the ampliphier. Try hooking up one speaker at a time to the amp and see if it does the same thing. If it shuts off on one of the two speakers, that speaker is most likely blown.

I turn on the amp then the fuse blows??


If the fuse only blows after the remote voltage is applied, the amplifier probably has shorted output transistors.

My amp works but my sub doesn't...!!!????????????


Whats the condition of your amplifier? New , Used, Old?

 

You might have a blown channel off your amplifier, this may cause little or no sound. You will have some distortion, crackle sound and then maybe nothing at all. What kind of subs are you running to it? Make sure the subs arent blown and check the voice coils to see that they are not torn off the subs , these are the 2 little silver or copper wires that are connected from the speaker connectors to the sub itself.

 

Let me know what happens?

The amps are probably going into protection mode. The wires are most likely not hooked up correctly. Make sure you have a good ground, good power source, and the remote wire is run correctly. Also make sure the speaker output wires aren't touching each other, and you have the correct ohm load for the amp. What kind of speakers/subs are hooked up and how are they wired?
