If the fuses were the problem then you would be replacing them all the time. Fuses are only good once - and are only in place to protect the circuitry from damaging overcurrent situations.

More likey, the problem is a thermal protection resulting from over-driving the amplifier. What impedance are the speakers you are running? Does the amplifier support that impedance? Typically, car audio runs 4-8 ohm impedance. Many amps have a switch to place the unit in the proper impedance mode.

Check your wiring. Do you have it wired correctly?

Check and see what size fuses it uses. Your watt power means nothing without good fuses. My suggestion would be to go buy 40a fuses and replace the ones you already have.

Can't really find anything about them but maybe if you contact Legacy and beg a little they might have a circuit diagram hiding away somewhere. Here:Legacy

I need to know the size of external fuses for a american legacy amp 2000 watt 2 channel 1990


25 to 30 amp fuses will work great, anything lower could possibly blow a fuse when a good bass note hits even if there is nothing wrong with the amp. Hope this helps.

PC SHUTS DOWN MONITOR AND FAN


Hi Brandy19960,

Thanks for the posting in FIXYA.

Please do the following steps:


Step – 1

Right-click on My Computer, open Properties, click the Advanced tab. Under “Startup & Recovery,” click Settings. Under “System Failure,” Uncheck the box in front of “Automatically restart.”



Step - 2


To change the setting, click Start --> Run--> type GPEDIT.MSC, click OK.

Drill down to Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options.

In the right pane, find “Shutdown: Clear Virtual Memory Pagefile.”

NOTE: Since someone actually has to have set this policy, the problem will be pretty rare, but is worth mentioning. However, Forum participant “roadrunner” reported that the personal security app Privacy Eraser automatically enables “Clear virtual memory pagefile,” and, therefore, may be the cause of a slow shutdown.



Step - 3

When Windows XP won’t powerdown automatically, the APM/NT Legacy Power Node may not be enabled. To enable this, right-click on the My Computer icon, click Properties | Hardware | Device Manager | View. Check the box labeled “Show Hidden Devices.” If it’s available on your computer, there will be a red X on the APM/NT Legacy Node. Try enabling it and see if this resolves the powerdown problem (Tip from Terri Stratton). Or, to check the other side of the APM/ACPI coin, open the Power Options applet in Control Panel. If there is an APM tab, make sure the “Enable Advanced Power Management Support” box is checked.


Step - 4
----------

Try a Shutdown shortcut -


For a shortcut to RESTART Windows XP:
SHUTDOWN -r -t 01

For a shortcut to SHUT DOWN Windows XP:
SHUTDOWN -s -t 01

Step 5
---------

WORK-AROUND: Disable power management for your USB hub: Open Device Manager (click Start, click Run, type DEVMGMT.MSC, click OK). Double-click to expand Universal Serial Bus Controllers. Double-click USB Root Hub. Click Power Management. Uncheck the box “Allow the computer to turn off this device to save power.” OK your way out

Step – 6
-----------
Click on the Start button.
Select Run from the menu.
In the run dialog box type “msconfig”.
Click OK.

Once in the msconfig utility select the startup tab. In the startup tab you will see several programs listed with a checkbox beside it. If there is a check mark beside the application listed, the application will startup when your computer starts up.

Problem with legacy amp


I would check the RCA preamp wires connecting the stereo to the amp. If these are loose or broken, it could cause you to lose your sound.

Does the amp show signs of life, such as clicking on, an LED turns on, or anything like that?

Has anything else changed between the time it worked and didn't work?

Installation


If you've got a standard 4 speaker system (2 front, 2 rear), your best option is to connect both left speakers to the left channel amp output and both right speakers to the right channel amp output. The only thing you lose is the ability to fade the speakers front to back.
