Power problem I have a problem trying to get my amp to power up. I have everything connected the right way. I know this cause I am replacing a smaller amp with it. My problem is that the amp will not power up and I dom't know what size fuse I need to put in the amp itself.

Problem in the part of the power supply that feeds the tweeter amp. Fix the power supply and epoxy the board where it needs to be epoxy. Best of Luck! Serge Lavallee.

A faulty starter could drain the battery but not completely.Sounds much more like a bad earth connection try attaching a jump lead or heavy cable between the negative battery terminal and the engine and try it again.

Hi
Assuming there is nothing wrong with the inverter or heater.
You need to check the voltage on the input clamps of the inverter (+ & - connections on the back of the inverter) when going under load, if the voltage is going under 12 volts as it is applying power to the heater there is a connection or volt drop issue.
The inverter is capable of drawing up to 190amps from the battery this can cause damage to the battery.
It is very rare for an inverter of this size to be used on 12 volts.
There are a long list of calculations which I am not going to bore you with, but for this inverter to run on a 12 volt battery system and not cause unesesary damage to the batteries you would need 8 x 120AH deep cycle batteries.

okay , well you need to make sure all your conections are in the right spots, and that your IN LINE FUSE, between your amp and battery, the big glass one is not burnt, just take a look at the metal piece inside , if its a sold metal piece its good, if its burnt in half like a broken bridge it needs to be replaced. the next thing is the fuse on your amp, you need to make sure it is not burnt also. Check your remote that it is hooked up to the right wire. then check that your sub/speaker wires are connected properly and secure. YOUR GROUND WIRE IS HUGE HERE also. MAKE SURE IT IS GROUNDED TO A GOOD SPOT, YOU MAY HAVE TO MOVE IT AROUND A FEW TIMES TO FIND A GOOD GROUND!!!! if you check all of these things, it should work fine.. you can fiddle with your amp and bass settings levels. turn em up so when it works you know it, but not too much you dont wanna blow nothing :)

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.

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

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.

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!!

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).
