Boss 5500 watt amp stays in protection mode


The amp is going into protection mode because one or more of the output transistors is fried inside. You want to check for resistance on all the outputs. I repair these everday. Either have it repaired or do it yourself. I buy broken amps and I also repair them. Let me know if you want to sell or repair or want instructions on how to repair it.

My A8000t amps red protection light is on checked


When ever the amp stays in RED protection mode with out any speakers hooked up to it, YOUR amp has internal damage some where. Can't tell you how much to fix, Could be cheap or not worth it. Talk to your local electronic repair, would be a good start.

Protect


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 . Send to Rockford Fosgate for repair .A thumbs up would be greatly appreciated if this answer is helpful to you. protect-zb4bomd1rt4qms0dqd12kkt2-3-0.jpg

My amp turns on and pumps once then it stops bt the amp is still geting power


First try unhooking the speakers and see if it continues to go into protect mode. If it does'nt then your speakers are running to low of ohms required for that amp causing it to go into protect mode. If it still goes into protect mode check your ground, might have a voltage problem and check voltage going into amp. I have read the manual and this amp has advanced circuit protection. So if all I have asked you to do and it still goes into protect mode then amp is faulty and has some output transistors shorted or power supply mosfets shorted. Let me know what you find. But you need to do what I have explained to narrow the problem down. Good luck, Keep me informed. I will be glad to help you thru this. I also have a business of repairing car amps and you will not find anyone cheeper. So if you want it repaired and you feel you can't do it, just send it to me and I will repair. If you decide this E-mail me at:skinnman33@gmail.com and we can discuss it in more detail. Just a thought to try and help you out. I have many customers that send me there amps and I repair them and ship them back. A few come from this site. Let me know

My protection light want shut off.


Not if the amp is damaged. An amp that remains in protect mode (after cycling the power) usually has an internal fault and must be repaired.

Protection light


If the amp goes into protection with no speakers wires connected to the amp and no signal cables connected to the amp, the amp probably has shorted output transistors.

If that's the case, they would have to be replaced. Most people simply have the amp repaired by a qualified tech. If you want to try to repair it yourself, read the following page:

Amplifier Repair Primer

If the amp failed after only a short time, the speaker ohm load may have been too low. If it wasn't lower than the amp is designed to run, the amp may not be suitable for your needs.
