    I have a similar problem. I have run all my wires from the same spots as I did previously (and they worked) but now I get no power to the amp. I don't get a green light or a red light or anything, just no power to the amp. I have checked all my fuses, installed new wires and anything else I could think of but still no luck. Any suggestions out there?

    Thanx moneyman, I tried hooking my rem to the battery direct and next thing know I have sound..... is there any chance that this would contribute to engine whine though? I seem to have a minor whine happening now.

Hmm...ive had this problem before and its always been either the remote wire, the rca cables or the ground. i would try hooking up the remote wire strait to the battery, if that doesnt work try to find a better place for the ground. maybe where your trunk latches. if that still doesnt work then i would try new rca cables.

Something, a component, in the laptop may have fried the charger. I don't know for sure. You would have to trace the circuit with a multimeter to locate the bad power component.

My 600 watt amp for my car just now start putting a red light on

You may need a new power supply inside amp. If you where running speakers with to many watts it will burn up the power supply. Try unplugging all wires. Replug them in also check fuse underhood and inside amp

600w legacy amp

9 times out of 10 if your amplifire is in protect mode and evrything externaly, like speakers, fuse, voltage, etc. checks out fine then
either you have shorted out output transistors or power mosfet transistors. Basicly that just about what happens with car amps.
It's easy enough to fix IF, IF you know what your doing. First you
need to check the output transistors with a digital volt meter on diode check, If they check out then check your power supply mosfet transistors. I can almost guarantee this is your problem. Very common. I buy non working amps all the time and repair them. Listen to pbabin also he has helped me out. Good luck

No light at all


A couple of things you can try:
1. check for B+12 on the 1st and 2nd terminals of the Power Connector using a voltmeter;
2. temporarily put a jumper on the 1st & 2nd terminal of the Power Connector;
3. the usual, check for loose connection, fuses, wires, connectors.

if there is +12 on both terminal and amp is still dead, then it is internal;
if there is +12 on terminal 2 but none on 1, then it is the wiring from the head unit or the trigger of the head unit that is the issue;

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

What size fuse do i need for amp

start with a 50, may need to increase it if you are not using a large capacitor.
600 watts = 12x
x= 600 watts / 12 volts
x = 50 amps

Power Problem, LED Lights up and then shuts off

Do you have the switch or activate wire on the new amp. to the right hookup? If you do, then theres a problem with the amp and if your not a tech these can be a difficult thing to trouble shoot. Take back the amp or seek out a pro to test it on a bench. Good Luck
