Amp Troubleshooting
 

I have a rockford punch 500 amp, 4-5 yrs old, that worked when i took it out of my car, but now i cant seem to get it to work, where if any is the fuse on these amps, or what else could it be, i unhooked my buddies operating amp, and plugged this one in, still nothing, whats the problem?

anyone?

Re: Amp Troubleshooting
 

does the amp have an inline fuse? are you sure the ground lug is tight, have seen that cause problems. Fuse should be on one of the two ends, very obvious.

Ground is good, other things work off the set up, the power wire has a fuse which is also good, however i cannot find the fuse on the amp, its not just out in the open, and its not under the cover

My Experience With Punch When They Don't Work Is Send Them Back For Repair Or Buy A New One. You Wont Find A Fuse.

where the F is the fuse

Re: Amp Troubleshooting
 

Does the lead for the remote turn-on have power? Perhaps there isn't any power going from the head unit to the amp? As others have mentioned, make sure you check the fuses. If you don't have an inline fuse close to the battery on the positive side, you need to. Ground needs to be very good as well or it will not work. I'm not overly familiar with Rockford Fosgate :(. Let us know what you find.

Are there any indicator lights on the thing to tell you what's going on? Does it have power or just won't power up at all?

Re: Amp Troubleshooting
 

there is a LED, and it does not lite up, no power at all

from the manual I dont see a internal fuse location here are some hints froim the manual
NOTE: If you are having problems after installation follow the Troubleshooting procedures below.
Procedure 1: Check Amplifier for proper connections.
Verify that POWER light is on. If POWER light is on skip to Step 2, if not continue.
1. Check in-line fuse on battery positive cable. Replace if necessary.
2. Verify that Ground connection is connected to clean metal of the vehicle’s chassis.
Repair/replace if necessary.
3. Verify there is 10.5 - 15.5 Volts of current present at the positive battery and remote turn-on
cable. Verify quality connections for both cables at amplifier, stereo, and battery/fuseholder.
Repair/replace if necessary.
Procedure 2: Check Amplifier for audio output.
1. Verify good RCA/high-level input connections at stereo and amplifier. Check entire length of
cables for kinks, splices, etc. Test RCA/high-level inputs for AC current with stereo on.
Repair/replace if necessary.
2. Disconnect RCA/high-level input from amplifier. Connect RCA/high-level input from test stereo
directly to amplifier input.
Procedure 3: Check Amplifier if you experience Turn-on Pop.
1. Disconnect input signal to amplifier and turn amplifier on and off.
2. If the noise is eliminated, connect the REM lead of amplifier to source unit with a delay turn-on
module.
OR
1. Use a different 12 Volt source for REM lead of amplifier (i.e. battery direct).
2. If the noise is eliminated, use a relay to isolate the amplifier from noisy turn-on output.
Procedure 4: Check Amplifier if you experience excess Engine Noise.
1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.
OR
2. Bypass any and all electrical components between the stereo and the amplifier(s). Connect
stereo directly to input of amplifier. If noise goes away the unit being bypassed is the cause of
the noise.
OR
3. Remove existing ground wires for all electrical components. Reground wires to different
locations. Verify that grounding location is clean, shiny metal free of paint, rust etc.
OR
4. Add secondary ground cable from negative battery terminal to the chassis metal or engine block
of vehicle.
OR
5. Have alternator and battery load tested by your mechanic. Verify good working order of vehicle
electrical system including distributor, spark plugs, spark plug wires, voltage regulator etc.

Ok, sounds like a power supply problem, you might be able to get it fixed, but be prepared to write this one off. How long has it been sitting around? Sometimes just moving a piece of gear can screw it up.

if you have power to amp and power to remote turn on and led doesnot light up prob liss it goodby
