    I hooked it up the same way my other amp was connected ground first then remote and then b+.I am absolutely sure of the wiring.I replaced both capacitors cleaned the circuit board new fuse and the saame thing happens.I guess i was hoping for a common problem so that i wouldnt have too take the components out to test ????

    Sounds like the +12 volts is being connected to the -12 (ground), i.e., hooked up backwards -- are you sure the +12 is being connected to the correct wire/terminal? What is the source for the +12 volts you are connecting to it? Charlie

  • Joel Friedenberg May 11, 2010

    Must not have the caps hooked up correctly. How is everything wired up? Try the amp without the caps. See what happens.

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.

Likely the amp has gotten too warm, and the PA (Power Amplifier) is blown out of it, or it is being bridged incorrectly. These amps suffer from generating lots of heat.

Not really worth repairing, my opinion. Can be found on 'net for pretty cheap.

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.

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.

Fuse
Hi,

There are only a couple of components that could cause the fuse to blow. They are:
1. Reverse protection diode (D23)
2. filter capacitor (C123)
3. Outputs (TR14 & 15)
4. Audio Amp (IC4)
5. Zener Diodes (D22 & 19)
6. the fuse itself (it should be 2 Amps

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FIXYA.

Rockford amp cut out
Disconnect all speaker wires from the speaker terminals of the amp and disconnect the RCAs. Replace the 30 amp fuse with a 15 amp fuse. If you turn it on and it blows the fuse, it's likely that it has shorted output transistors. If that's the case, you need to have the amp repaired.

Blown fuses

If the fuses only blow after the remote voltage is applied, the output transistors are likely shorted.

 

According to the owner's manual, the amp should have two 20 amp fuses.

Lanzar amp
If it keeps blowing fuses then #1 its internally damaged or "blown" .. Or #2 i would make sure you have the battery power hooked up to the + terminal and the ground wire running from the car body to the - terminal.. so if its hooked up correctly and keeps blowing fuses then it requires repair..
