Question about AudioBahn A2502DP Car Audio Amplifier

1 Answer

Started blowing fuses

Wiring up this amp for the second time (after having it sit in my car for 4 years -- long story), a wire from the battery touched the case. Now it just instantly blows the fuses I put in. It appears that somehow, I've shorted out the circuit. Worth taking it apart and looking, or did I just throw all that money away?

No you have created a solder jump fusing the circuit together I suggest buying another amplifier rather then repairing it you can buy a new amp or anything audio wise at dealer wholesale cost at this site:

Kicker amp 350.4 blows fuses


Check your wiring for any exposed. Make sure there are no wires touching and that you have the proper gauge wiring for that size amp. I used 4 gauge with that same amp and never had an issue.

I installed a planet audio TW402 amp in my car. i put this amp last summer. when i first put it in my car with an sony xplod sub. i had a very small 12 gauge power wire and ground wire. but still it worked...


It could have to do with how your speakers are wired. If you have 2- 4 ohm speakers and they
are both wired to one terminal (RIGHT OR LEFT) on the amp, you have a 2 ohm load and most amps are rated at 4 ohms.
Go to this site and use #58 on the right sidebar to see if you are wired correctly.

My amp keeps blowing its fuses whenits plugged in


Go over all your wiring. Make sure your power wire isn't grounded somewhere. If your power wire is touching any bare metal it will spark and blow the fuse the second you touch the power to your amp. Make sure your in-line fuse is about a foot from your battery, and make sure you have your ground wire grounded securely to the main chassis of the car/truck and that it is either same size gauge as your power or even a little bit bigger gauge. Also make sure no strands of wire from your ground or power wire are loose and reaching over touching the other where you plug them into the amp. If the ground and power touch eachother they will blow the fuse and possibly cause permanent damage to the amp.

Every time i turn my amp on it blows the fuse what do u think is wrong with it?


Hello! Is this a new installation? If so re-check your wiring... If not, tell me what the year, make, and model of the vehicle...Also identify which fuse is blowing; vehicle fuse or in-line amp fuse?

your inline fuse wouldn't blow if there was just something wrong with the amp. the amp fuse would blow if that was the case. something is faulty with your wiring. you probably have the wires touching somewhere or are in the wrong terminals at the amp or on the wrong battery terminal. or your power wire is grounding out somewhere. its not the amp. its your wiring

I have a dual XIA3145 580 watt amp that keeps blowing fuses


Generally, this indicates that there's at least one shorted output transistor.

Disconnect all speaker wires from the 'amplifier's speaker terminals' and disconnect RCA/signal cables from the amp. If it powers up normally, the speakers/wiring need to be checked. If it still blows the fuses, the amp almost certainly has shorted output transistors and will need to be repaired.

I'd recommend using two 10 amp fuses. The amp will power up with 10 amp fuses if there is no problem. If there is a problem, there's less of a chance of doing more damage by using the 10 amp fuses.

Let me know if you have any other questions.

Ground zero amplifier overheating and going into protect.


Since you changed the amperage of the fuses and the cable, you allowed the internal problems of the
amplifier to get worse than they were before the original fuses started blowing.

A fuse is a safety instrument that blows instead of your amplifier.

The problem is NOT the fuses frequently blowing, as such events warn you of internal problems with
the amplifier which you should have had serviced at the time to prevent them getting worse.

It is very much like the persons who replace the fuses in their household wiring with pennies, to prevent
frequent fuse replacement only to have their house burn down from overloaded circuitry.

Service your amplifier immediately.

Revert to the original amperage on all fuses in your vehicle to prevent a car fire.

Amp keeps blowin the two 30amp fuses on the amp.


Make sure that the speaker wires are wired correct at both the amp and the speakers......otherwise it sounds like the typical death of a power acoustik amp (great amps, but prone to a premature death)

When i hook up the remote wire it makes my power wire go to 4 volts


If the battery is strong enough to start the engine, you probably have a bad connection or a defective fuse in the power wiring. If you solve the voltage problem and the amp blows fuses, it likely has shorted output transistors.

40amp fuse blows


Measure the DC voltage across the B+ and ground terminals as well as across remote and ground. If you have less than 11 volts when the amp tries to power up, the amp could be shutting down due to low voltage.

If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down or blows the fuse when you apply remote voltage (turn the head unit on), the amp likely has blown output transistors.
