Amp Power light will not go on. Protection light is lit- Thump sound in speakers

well, basically... the 12v (+) power wire is fused and hooked to the battery and ran to the amplifier, then run an amp turn on wire from you radio its usually blue with a white stripe (if you have an after market radio) then run the rcas from the radio to the amp and finally tap the ground (usually and cleaned bare-metal on your car close to the amp).... if you give me some more info i can help u further... what is the make/model/yr of your car, what radio do you have, amp, sub, speakers, etc....?

Well you have a high impedance path to your amp. If you have an inline fuse that should have blown. Car batteries don't have a current limiting feature HA The only explanation would be that the amount of current passing through the wire is causing a large voltage drop due to a large impedance. What gauge wire are you using? Here is an example.

18 ft of 8 gauge wire would have to be passing about 400 Amps of DC current to yield a voltage drop of that magnitude. The wire would melt and all hell would break loose. So there has to be a break in your wire somewhere.

MOST OF THE TIME AMPLIFIED BOXES ARE EASYER THAN REG AMPS, ALL U HAVE TO DO IS RUN UR RCAS FROM THE BACK OF UR HEAD UNIT TO THE AMP, THAN UR POWER LEAD, FROM UR BATTERY TO THE AMP, THEN UR GROUND MOSTLY ON THE FRAM OF THE CAR OR ON THE BRACKETS ON UR SEATS, THATS MAINLY ALL U NEED TO NO.

disconnect speaker,turn gain down to about 10%.repower amp check and see if protection light comes on.if it does recheck power,remote,ground,if it doesent go into protection then kill power and rewire speakers

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.

220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
the amplifier may be over-driven. are there red protection lights coming on the front panel? Or a loose wire - power, ground, or speaker.

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.

For the visonik, you should check your speakers. You can use a D-cell battery. Remove the speaker wires from the amp and connect each speaker across the battery (for no longer than a few seconds). The speaker should pop each time the wires are touched to the battery. If they don't, the speaker is defective (assuming the battery isn't dead).

If the speakers are OK, you need to confirm that you have a good signal feeding the amp. You can use the RCA cables from another working amp in the vehicle. Do this with the amp that had the power light lit.

If you have signal going to the amp and the speakers are OK, the only two things left are the power supply feeding the amp (from the battery) and the amp. If you have B+ and remote voltage AND a good ground, the amp is defective.







For the pyramid, the amplifier probably has shorted output transistors. The amplifier will have to be repaired.

was the amp hooked directly to the box? You probably rattled the power connections from the circuit board like I did on a PT 800 watt amp.but check amp fuses first.

It sounds like your saying that you have two identical amp, that both are on the same power wires and remote wires and sam grounds? Well if thats the case then you did ok as One amp sounds like its blown. First tghing is check the main fuse. If its good and the unit still dosent resond then the power supply in the amp is blown as theres a switching supply that increases the 12 volts to get power to drive the Mosfet output devices. Was it ever working?? yes then the amp needs service. Do you know how to work on solid state elctronics down to componet level?? No?? Ok contact these folks at the addy im posting for you or take the amp to your local servicer. Good Luck. [email protected]
