Re: power problem

Do you actually see a fuse in it? If there is a fuse it should typically say on it what the rating is.

Old Amp blew, got a new one. Power light came on but speakers didnt work. Unhooked the amp, hooked it back up and no power. Any ideas?

Are the speakers still working? When the old amp blew it might have blown the speakers too. Are any of the wires grounding out besides the ground? I would check the remote wire too. I also suggest replacing it with a bigger (smaller #) gauge wire, its not as sensitive to interference and gives your amp a boost in actual power to the speakers. Check any fuses to see if they are blown. Make sure all the connections are tight. If no power after this all checks out then amp is blown again and you might want to get smaller speakers or a bigger amp (or better).

My amp keeps going into protect

do you have the right size ground wire, relative to your power wire? If your ground is smaller when you turn it up there is alot of power it needs an exit and if the wire is too small it travels elsewhere maybe your rca, causing your amp to protect.

Amp wont turn on

have you checked the remote wire is supply power? try jumping the main power wire t the remote wire to see if it turn on. Also check that your ground wire is securely making contact.

Power problem amp

Sounds like its going into protect mode-try disconnecting the speakers from the amp entirely and turn the system on if it stays lit up- then ya know its the speakers (one of them at least) thats making your amp shut itself down. If thats the case look into replacing the speaker thats causing the problem.Also make sure that you have sufficient wiring to your amp - at least 8 gauge if you can. check all terminals /power/ground make sure everythings connected tight and not grounding out anywhere

Possibly you need to return the amp and get a new one cause that could mean an internal problem and its deffective, you could try replacing the fuses or try changing the ground wire, this problem is very unusual

My kenwood amp wont turn on

What kind of "Clips" did you put on? They may be causing too much resistance and preventing the amp from getting the current it needs. Double-check with a voltmeter that you are getting at least 12 volts at the amp power connections and make sure your ground lead is as short as possible and connected to solid metal of the vehicle's chassis.

you Amp is overloading and going into protection mode. if it cuts out with the wire u were using first then their would be no need to upgrade the size of ur wire cause that would only be, doubling or trippling the power u are getting threw those wire now. bottom line the 2 subs u are using are obviously to much for the amp. try dropping the OHM's by connection the subs together and runnig just a single positive and negative to the amp! or just get a better amp

Sony explode amp for my car

Try disconnecting everything but the power connections. If the protection light still comes on, then there's a problem in the amp. If it goes out, then there's a problem elsewhere. In that case, hook up one speaker cable at a time and power on. If the protection light comes on, then either that speaker is bad, or you've got too many speakers connected to that one amp output. Too many speakers connected together can cause an overload and trigger the protection circuitry, or worse, blow out something out.

Hope this helps, and please rate my advice.
Thank you, and good luck!!

Amp blowing fuses

The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).

Amp is not coming on

the fuse may not be working, you could try a larger sized one, also if you have the old power cable try it again with a larger fuse in place, if it worked before its likely to just be the fuse wasnt big enough, check all the other connections are in the right place, if they all are and you know the amp hase worked before then it could only realy be the fuse isnt big enough or the power lead is faulty.

cheers, adam
