Hi, when the fuses blow it can only mean that the current the passed thru it is greater than its rating. It is possible that the fuses installed has a lower rating than is required by your amp. To check look over the specs of your amp and determine the proper amperage (amp) rating. Specs may be found on a sticker at the bottom or side of the amp and may look something like 12V-20A meaning 12 volts 20 amperes. In the absence, you may want to check the box and/or the instructional manual that came with it ot go to the manufacturer's website to checkout the specs. If you are referring to the fuse serving all your amps, players, receivers, etc, then you have to addup all their individual A rating and get a fuse whose rating is equal to the addedup value. Although this is not a sound practice and individual fusing is preferable. If the amp rating is equal to the fuse rating but it still blows, then you may want to have your amp checked. Trying to install a higher rating will most likely prevent fuses blowing and present itself as a temporary solution but the real problem is not solved and may be aggravated. Hope this be of some help and good luck.

1998 sunfire installed stereo and now dash lights and tail lights blowing fuse


Get a wiring harness connector for your 1998 GM car - THEN carefully follow each wire color on the harness. Do NOT connect anything to the GM orange wire except "Memory". Do NOT connect anthing to the harness for "Lights" or "Dash" or "DIM" - you will blow fuses. Only connect the Power, the memory and the speakers - period. Then you'll be safe.

It keeps blowing a fuse


Generally, if you are using the manufactures fuse rating you can use a slightly higher rating and it will resolve the blowing fuses. Fuses supply resistance, if there isn't enough resistance you'll fry the system board in the amplifier. But if you have 25 amp fuses installed, install 30 amp, if you have 30 install 35 amp, 35 install 40. Anything higher will damage the amp.

Hope this helps.

A rare chance, something may be internally wrong with the amp and shorting it out which will blow the fuse.

Use the incorrect wiring of subs to the amp, you'll blow fuses and damage the amp from it turning off consistently. The amp should be running at 2 ohm stereo stable or 4 ohm mono stable.

Very few amps are designed to run at 1 ohm or less. Not to mention the subs can't handle it.

Blows the 30 amp fuses


yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

The power fuse blows as soon as the unit is plugged in


There is a problem with the amplifier within the sub. Many of these units never completely turn off. They are often set to automatically startup when a signal is detected. This may be the case here. The loud hum as a defect in the output amp section. At this point you probably have a blown amp section. The "protection" for this is to cause a dead short that will open up the fuse. This unit will require service. It is unlikely that any service info is availabel to the general public either.

The fix could be simple, but without seeing the unit, I can not state that for sure.

Keep us posted.

Power surge blowing fuses on amp when car is turned on.


the voltage regulator in the alternator or the capacitor is malfunctioning. get a multimeter on the battery when u start the car (before the capacitor) if it reads a large surge (something greater than 14 or 15 volts) then u may need a new amp, if not, then test it on the back end of capacitor to the chassie negative, see if u detect spike there.

Fisher CA-273 amplifier left speaker ports


fuses will be on the inside of the amp. you will have to disconnect it from the power and open the box to get at the fuses( some fuses are accessible from the outside of the amp) also, you may have blown the input or output section of your amp. this is not easy to fix at all. you can blow it from playing your music too loud or from a loud source. while the case is open, have a look at the solder joints on everything. if anything is brown, covered in white residue bulging, melted, burned or looks disconnected, that is probably the problem.

Amp blowing fuses


The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).

What eq settings do i need


Hello ed4037, If you are blowing fuses this means that you are drawing too much current check your impedance value on your amplifier it should be 8 ohms to match the subwoofer's 8 ohms of impedance. In addition make sure that you have the proper value fuses. In other words you should not be tuning the amp not to blow fuses, because you should be able to go to full amplitude on your amp without blowing anything. As I alluded to this sounds like an impedance mismatch problem. I hope this helps, Thank you, Shuttle83
