Re: Blown capacitors

There's hundreds of capacitors in an amp... The value should be printed right on them. It will have a Farad rating (F) or usually MICRO farad (uF) and a voltage rating (V). Looks like "16V 47uF"... Be aware that there's likely to be more problems than just the caps...

Pyle PLMRA 400watt marine amp.

I'm assuming you mean channels 2 and 4? If you tried new cables and you know they work then you might wanna check to see if there is a 2,3,or 4 channel switch on the amp or just a switch that reads bridged. If a switch on an amp is set to bridged or 2 channels, whatever type of switch there is, then it would make the amp only run 2 channels. If there is'nt a switch and you have a signal on the cable your using then you may have some shorted transistors. Make sure you definately have a signal first before thinking some transistors are shorted. Take the rca's from the 2 channels that work and put them into the inputs cause you know those channels are working. Let me know what you find, I would like to help you more if you still have problems after this. I also do amplifire repair cheap. I have my own business and most of my customers are from this site, so if you need it repaired then I can help you out on this as well. Just send me a private message. Good luck

My fuse blew out on my Pioneer amp

Could have been caused by a few things.

1) Low voltage. Most car charging systems aren't equipped to handle the extra strain of amplifiers without some sort of help, if this is the case you may need to add, a capacitor or battery.

2) Blown sub. Sometimes when you blow a subwoofer, it can take your amp down with it, most amp's will go in to protect before this happens, but not always.

3) Over driving the amp. If you max the gain, and bass boost on your amplifier, you can cause all sorts of problems, including blown fuses.

4) Loose or bad connections. Check your connections to the battery, and ground, sometimes a loose connection will play, but cause your amp to over heat by working to hard to produce it's power.

5) Bad amp. Could be a factory defect, like a poor soldier joint, or bad component.

What are the correct spaekers for the gm 5100t ?

    CEA-2006 Compliant Amplifier Power Standard:
  • 125 Watts x 2 @ 4 ohms <= 1% THD+N
  • 380 Watts x 1 @ 4 ohms BRIDGE <=1% THD+N
  • 75 dBA Signal-to-Noise Ratio
  • Peak Music Power: 250W x 2 (4 ohm) / 760W x 1 (Bridge)
  • 2 Channels
  • Continuous Power @ 4 Ohm: 125W x 2
  • Continuous Power @ 2 Ohm: 190W x 2
  • Continuous Power Bridged @ 4 Ohm: 380W x 1
  • Frequency Response: 10Hz-50kHz
  • THD (1kHz, 4 Ohm): <0.015%
  • Signal to Noise Ratio: >95dB
  • Dimensions: 11 13/16” x 2 3/8” x 12 7/8”
  • PWM Regulated MOSFET Power Supply
  • Balanced Isolator Input Circuit
  • Oversized Screw-Type Power/Ground Terminals
  • 2 Channel RCA Inputs
  • Speaker Level Input
  • Screw-Type Speaker Terminals
  • Hi-Volt Input Level Control (200mV-6.5V)
  • Bass Boost (50Hz, 0/6/12dB)
  • Selectable LPF (80Hz, -12dB/Oct.)
  • Pioneer 1-Year Warranty
I'm assuming the subwoofers were bridged and couldn't handle the power. Make sure you have atleast 300 watts peak power wattage.

Check Power cable fuse, check ground is grounded to non painted surface.
This is all you need to get it to work. If you still have a problem, then it is a bad capacitor inside the amp

Kicker 750.1 Amp wont play music

it is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs

Protection light stays on no output

i have the same amp and have that same issue before. yes you are correct that if you take off the RCA cables on the input there will be no light. either you have plug the remote line on the 12v or a grounded sub. it should be 12v/remote/ground from the corner. good thing im just fixing my sub earlier. it is no problem if you have hooked the remote line on the 12v, it is the same supposed to be. to check if your amp is working, short the 12v/ and the remote line and play your stereo and see if your sub is working. by the way, what sub are you using? i just blew my sub and need a new one.

Have you checked the RCA leads at the radio? Usually if you not getting sounds one of two things is wrong. 1.Rca leads in the amp are lost or broke.2. Rca cables are bad or pinched and the radio RCA's have burnt out.

Blown amp

hi, try connecting the power b+ and gnd and remote turn on cables only (dont connect rca input or any spks), if amp doesnt turn on you will have to take in for repair. no need to buy new amp, coz problem could be a burnt pcb track or even a faulty remote or FET circuit.if amp turns on then connect other cables slowly and monitor the power lite as you do connections. you may have a faulty spk load that will cause amp to stay off or in protection mode. cheers

Half my amp works

Im sorry to tell you, that if only one side is working, you most likly have an open driver transistor or input device. If the one side had a shorted output then the whole unit would go into shutdown. The fact that the unit still works is a good sign. The correct way to test an amp is with some equipment most folks do not have, and that means a trip to your local good audio repair facility. They will need to doi a bench check on the amp with load resistors and a tone generator. If the amp preforms good on the bench, then you should start looking for bad speakers and or pinched wiring,loose connections or bad speakers. Let us know what happens? Good Luck
