LED Light is on, but no sound from sub at all.. Have double backed on all wires but still nothing! HELP!!

Ok so I think I put the sub into protective mode but I thought if it went into that mode the LED turns off. Mine has been working fine for a while now but when I was listening to it down on vacation it cut off. I thought it was overheated so turned off the radio and let it cool down. Next day, same thing, LED is on but no sound from sub. So I replaced all speaker and RCA wires and checked the fuse (not blown). Still nothing. I dont understand what it could be. Maybe there is some type of reset button? I need some help pleasE!

I just brought mine to the shop for the same reason. I thought it was something big but it was just a bad fuse. It wasn't blown so when i checked it, I didn't think anything of. If you're using an AGU fuse, try and remove the fuse and touch the two ends of your power wire together and if it's the fuse it should cut on

If you've overheated it a number of times, it's possible that you've damaged the amp and it's trying to protect itself even though it's too late. Try disconnecting the sub from the amp. If there's no change, then there's a problem within the amp. It could be a thermal switch or possibly a stressed amplifier module.

Hope this helps. Good Luck!!

there's a problem with your amp, try checking your fuses on the side of the amp first, if they look ok then check the earth cable which is the black cable. If it is still red, it indicates that the amp is in safe mode which means it is on but would not power anything because it doesnt let power go through, meaning that there is something wrong with the amp. Open the amp up and look for the copper coils inside it. Rub your finger in it, if you get a blak residue it means the coils inside the amp have blown. If this is the case and the coils are blown, chuk your amp out its worth no more than a dollar if you can evn find sum1 to buy it.

I have checked all connections to my amp battery,head unit,remote or trigger wire,fuses,power cable,rca leads,ground wire,amp has a green led light on it indicating if it works ok,red if it`s not,light...
Your amp could be in protection mode! Sometimes turning up to high or wires touching will put in protection mode! It will have to be unplugged for a day or two to drain all power out of the memory. Leave accessorie/ignition wire hooked up, just not power and ground wiring. It should reset itself.

No sound
hi there
on your CD deck or what ever unit you plugged the RCA wires to needs to be set on subs the radio needs to be set to put sound to your amp.....on your CD player if you press the F/function button a few times it will scroll to SW which is for the subs set this to the on position or if your CD player has a button with SW press it and turn on this feature......if this has been done......check the fuse or fuses on the amp.......if you have done all of the above check the back of the CD unit to make sure you are plugged into sub-woofer RCA or R (rear) RCA ..........sometimes people accidentally put the RCA wires into the aux input RCA,,,,,, double check this.........
hope this helps

No sound
did you set your gains and base boost also when you put sterio back in dash did you put rca's on proper outputs or the rca's could have pulled out when putting back in
you have high output and low output

are your subs getting sound to them at all any current going threw speaker wires to subs
radio settings might not be set to back end for subs this is a feature on most receivers to shut off back end subs

My amp is on but no sound
Did you disconnect the battery? You may have bowwn a fuse, but that prolly wouldnt give you a protect light. Protect light usually means a short circuit, probably on the speaker end, sure there couldnt be maybe a single strand of wire crossing over the positive and negative speaker or amp terminals.

Problem with amp...
In virtually all instances where the protection light is illuminated, the amplifier has gone into protection because the output transistors are shorted. To eliminate external wiring problems do the following.

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still goes into protect, the amp likely has blown output transistors.

If it does have blown outputs, it's is likely due to the speaker wires shorting together when the woofer was out of the vehicle.

Stop putting out sound to subs
Ok This is a two channel High Current amp. It is stable to one ohm. If the Subs are single voice coil at two ohms the they have to be wired in Parallel that means (Red +) (Black -) are connected to the + and - of another sub and then the (RED +) (Black -) from both go to one output channel of the amp. You pair the other two in the same fashion on the other output channel. If you are getting no output (sound) at all first check if the amplifier is going into protect. (Usually indicated by a red led on the unit. If it is connect only one Sub to each output and see if the protect LED goes out. If it does then you should have sound at the subs. If not check that you have the sub output enabled on the HU some head units do not come with the sub output enabled on the HU. If every thig is enabled, with only one sub connected to each output and the protect LED is not on then your amp is probably blown and needs repair. Nice thing is that MA has a great warrenty policy. Check and make sure the protect LED is off. If it is on you probably have the SUBS wired wrong
