I have 2 amps instalkled in my car one is sony 1200w 2 channel amp for speakers and one is solid audio f2500d for 3 subs my sound and every thing was good but suddenly from yesterday im having trouble when...

First disconnect the CD head unit from the sub amp and see if the other amp works. If yes, the problem is the wires to the amp, the amp itself, or the subs/sub wiring. If no, the problem is the head unit--probably an internal short.
If the other amp works with the sub amp disconnected, reconnect the sub amp to the head unit, but disconnect the sub wires from the amp. Try the CD player. If the amp goes to protect with no speaker wires attached, the amp is bad. If the amp is OK, the problem is the subs or sub wires. Hook the wires up to the amp again, but disconnect them from the speakers. Try the player again. If the amp goes to protect, the problem is the amp wiring. If not, the problem is the subs. Check the impedance of each sub using an ohmmeter to determine which amp is out of spec.
Please let me know if you have questions, and thanks for using Fixya.

My protect light is flashing from red to the green power light it makes a thud noise in the sub when it flashes i have checked my ground and power it all seems to be fine does any1 have a idea on what...

You either have a short in your wiring (between the amp and the sub) or have wired the sub(s) at too low of a resistance. If for example you have wired it to 2 ohms, when the amp can only support a 4ohm minimum, the protect light would come on once you tried to turn up the volume a bit. This may happen if you have lost the wiring off one of your subs or one of the voice coils, thereby affecting the total resistance.

I have a bamf 5500 series and the amp is on and working but when i turn up the volume the amp will go into protect mode and stay there untill i turn the volume back down then the amp comes out of protect...

you probably have a blown sub(s) that short out when the volume is turned up. it would be a good idea to find out which one(s) is bad and replace it. sooner or later it may make the amp go bad if not replaced or removed.

I have polk amp that is powering 2 12' subs but itis flashing up with low amp/short light with a little buzz noise?

you must check your wiring from head unit back to subs even take subs out of box to make sure no wires are lose 99.9 of the time a wire has come lose which can be bad if your bridging sups as it changes ohms with 1 or 2 subs hope that helps oh and check volts from you batt and check volts at fuse spots and after fuse to make sure your geting at least 12 to 14 volts cheers i just had a ***** of a prob my subs worked but **** bass found out head unit sub out craped out

Jl audio 500/1 amp low ohm light at high volume

I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

Sub makes loud noise when car is shut off

Does it make noise if the RCAs are unplugged? If not, the RCA shield on your head unit may be burned open.

If the amplifier is set to signal sense, it will take longer for the power light to go off.

My amp works but my sub doesn't...!!!????????????

Whats the condition of your amplifier? New , Used, Old?


You might have a blown channel off your amplifier, this may cause little or no sound. You will have some distortion, crackle sound and then maybe nothing at all. What kind of subs are you running to it? Make sure the subs arent blown and check the voice coils to see that they are not torn off the subs , these are the 2 little silver or copper wires that are connected from the speaker connectors to the sub itself.


Let me know what happens?

Protect light flashing/ticking

this problem sound like you have too low of power going to your amp, test your battery and make sure its putting out enough power for at least the mininum amount of power that your amp requires, you can find that information in your manual or sometimes they post it on the amp itself. i hope this info helps
