Re: my amp has power the led is on but no sound

See what happens if you apply a temporary ground connection to the RCA input jacks ground connection while it is running. You might want to turn the volume down before you do this just in case it works.

I have a Directed d2400, it turns on and sounds great but when I shut off my car the amps esp light stays on and the top blue leds also stay on. For some reason when I connected my ground wire it sparked a...

So it is receiving power but not turning off? Sounds like the sense cable is not connected correctly. Amps have a sense cable that determine whether or not the head unit is powered on. They use this sense to power on or power off. If the sense cable is connected correctly and is getting the correct voltage, then the relay may be broken.

My fosgate amp was workin an now it wont trun on can u help me out plzzzzz.....thanx for ur time...

First check your fuses, all fuses. Then check to see if it's getting voltage to it, look to see if any of the LEDs are lit up, power, protection (over /under voltage, overload (short)) or none. If the power LED is lit & no others then check your RCAs coming into the amp by replacing them or using a multimeter set to ohms to make sure they are not loosing a connection due to wire breakage inside the casing. Cheap RCA's will easily disconnect inside the plug just from twisting them. If they are good and are not disconnected from the head unit, then check your speakers for damaged coils or loose wires, who knows they may have fallen off? If your amp has more than just power LED lit then you may have a short in your speakers or wiring disconnect the wires to see if the protection LED goes away. if not and it's still lit then repair the amp. If there are no LEDs lit at all, check your remote turn on wire from your head unit to make sure it sends out a 12 volt signal to the amp. You can also jumper a wire from the 12v battery connection over to the remote turn on connection to see if it will power up. If not then check power wires and connections, fuses, Battery , alternator, voltage regulator, etc.. any thing that has to do with your cars electrical system may have fried from the current draw by your amp.

How do you install an amp in new cars when the factory radio is basically an computer and doesn't come out of the dash?

You need to use a Hi Low Converter. They have a different name but I cant think of it right now. Basically it connects to your rear speaker and converts it to RCA connectors that you could connect to your amp. Then connect your amp to power (battery) and Ground to power it up. Last thing to do is connect yours speakers to the amp.

Also get a high Low converter with remote connection.

Ok, I am assuming this is the 600 watt amplifier?


Supplies needed:
- 8 Gauge power wire (long enough to run from your battery to the amp placement) WITH an inline fuse!!
- Depending on your stereo (if it has amp pre-outs or not) you will either need RCA cables (long enough to reach your amp from your stereo) OR a Line-Out converter AND RCA cables.
- The power lead that connects to your "REMOTE" line on your stereo (long enough to reach from amp to stereo - usually blue)
- A good ground wire ( long enough to reach a metal part of your car from the amp)

STEP 1: Find a spot to run the power wire from your battery - through your firewall and into your car - and then to your amp. (DO NOT CONNECT IT TO ANYTHING YET)
STEP 2: Remove your car stereo and look to see if you have PRE-AMP outs (RCA connectors for an amp on the rear of the unit)
A- if you do, GREAT.. proceed to step 3
B- if you don't.. you will need to get a LINE-OUT CONVERTER - what this does is converts the higher signals from your standard wires on your radio, to RCA style wires to connect to your amp.
B2- you will also want to buy a wiring harness kit for your stereo, unless you want to hack away at your factory wires.. (not recommended) - connect the harness kit to your factory wire harness, wire in your leads for the output converter, and run the other end to your stereo.*
*you will need to know which wires run to the speakers you plan to power with the amplifier
B3 - once the converter is properly connected - proceed to step 3
STEP 3: Plug the RCA cables into the stereo or converter, and run them properly from behind your radio to the amp but DO NOT CONNECT THEM YET.
STEP 4: Connect the REMOTE wire from your stereo to the same wire for your amp . (this enables the amp to turn on/off with your radio.. otherwise.. you will have alot of dead batteries)
STEP 5: re-install your stereo into the car.
STEP 6: Connect the RCA speakers into the INPUTS on your amp
STEP 7: Connect the REMOTE wire to your amp.
STEP 8: Connect the speaker wire from the OUTPUTS on your amp to the speakers you wish to power
STEP 9: Connect the POWER CABLE to the amp PROPERLY
STEP 10: Connect the GROUND CABLE to a metal part of your car (sheet metal, not just a bolt)
STEP 11: Connect the POWER CABLE to the battery cable
STEP 12: Re-connect your Battery
STEP 13: Start your car, and test your radio.

If you have any issues from here.. you need to re-check all of your connections.

Put a patch cable from send to return on the effects loop in the back of the amp and see if it goes away. I would check your speaker, connections and speaker cable also. Is this a head or a combo?

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?
