100a2 amp not getting power

This might be a problem with my deck, but, my amp will not power up at all. I have a good ground and I am definitly getting power but the amp will not power up at all. It is hooked up correctly as far as I know. All cables are brand new. Maybe the remote is not engaging the amp? Any suggestions. Things that I have tried 1. Rewiring everything with brand new wiring 2. Trying both RCA and hard wire hook ups 3. Grounding back to the battery 4. Scratching my head 5. Sticking my finger in a socket to try to get the light in my head to come on.

Re: 100a2 amp not getting power

Get a strand of wire and jump it from the power to the remote if the amp does not turn on then take the amp and smash it over and over again because it is fried

Amp is not turning on but all wires are connected properly what can be the issue

check the power wire fuse. Also, make sure your ground won't budge if you move it side to side. Make sure there is not paint there on the ground as well. last check power at the amp. use a meter and see if you getting 12 volts from the power wire and remote wire. One of them is not getting power. It's the only logical answer.

Noise through car speakers when connected to amp

If the subs are making a humming or RPM sound check your ground on the amp , make sure its a good ground. Always run your power wire from battery by itself down one side of vehicle. Groun should be no longer than 2 feet. If that dont help you can buy a noise supresor that goes inbetween your head unit and amp through RCA's with a ground on it . Hope this helps.

Amp won't turn back on, all fuses fine, all connections good

that sounds like the amp might have a bad ground.

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

Prot. light at High vol. (forget Bass CD)

You may have the speakers wired for the wrong impedance.

How many ohms per voice coil?

How many voice coils per speaker?

If the speakers are DVC, are the coils of each speaker wired in series or parallel?

Are the speakers bridged on the amp or one per channel?

Punch 100a2 problem ouch

Without the proper training in electronics , Nowbodys goping to be abl to explain to you the way to trouble shoot something without you knowing the lingo and also what the terms mean and do!. You also need to know how to use a multimeter, an ocilliscope,have load resistors to hook up to the amp . A good power supply . You also will need to know how to read a resistor as the resistor color code. And Know how to test capacitors as well as a solid state device. im sorry i cant help you but I wish it was that easy to do or I wouldnt have went to school all these years. Send the unit into the factory or to a repair shop as you could cause more damage if you short something out by accident. Good Luck
