Re: car battery

Your description is missing some detail but it sounds like your alternator is damaged. Take your car to a service center to have it tested.

I have a t3002 going to a L7 12" sub. it played for bout 5 minutes down my road then no sound. the protect light is on. Y?

It could possibly be a bad ground. I ran in to the same problem the other day, but I wasn't driving. Started my car and everything seemed to work ok then all of sudden nothing. I checked all the voltages when the car is turned on, remote turn on (should have more than 11v), power cable to chassis ground (12+ V), they were all there. Then I finally checked the ground just moving the connection turned it on and then off. This occured repeatedly, then I disconnected the ground and then reconnected, now amp is running like a champ.

Car subwoofer problems

The cable should not cause the problem unless it is shorting out somewhere on the remote or positive cable. I would use a larger gauge wire first as this is the cheaper way to go, and if the same problem occurs you are having a short in the sub or box causing the protection mode. You will have to back trace to find possible cross connections.

Memphis PR300.2 Amp protect light on

If it is not turning on your problem is it is not getting power. Check your fuses. The reason an amp goes into protect mode is usually because the subs are not wired up right. Make sure your fuses are good, you have a good ground, and make sure your amp turn on wire didn't come loose when you were putting the deck back in. As for the amp going into protect you probably wired the subs down to too few ohms and the amp you have can't handle it. Try hooking the subs up straight w/o bridgeing them and turn it up to see if it works. If you don't have problems with it then you wired your subs wrong.

Amp is shutting off after 10 min of driving!! please help!!

Does it happen at all volume levels?
What is the gain setting on the sub amp?
Have you checked for 12V @ remote turn on after problem occurs?
Sounds as if the remote turn on relay inside the amplifier is losing signal, or has become damaged. If the protection light does not light up, the problem is not thermal, shorting, or high/low voltage.
The amplifier is in need of repair. This is not an end-user fix. Looking at about $50 to repair.

Thanks for using FixYa- a FixYa rating is appreciated!!

The fan on my 1200 watt inverter does not start when turned on.

No. the fan is to remove heat(obviously) If there is a small or no load on the inverter the fan wont come on(no heat to get rid of)..........this is so a lightly loaded inverter wont kill your batteries as fast.If you load it up(power something big or power several things at once) the fan should start after a few minutes
hope this helps.Good Luck!

Geo Prizem no power to start as key is turned

It is possible that you burned out a fusible link (a short piece of wiring, specifically designed to fail, to keep your car's wiring harness from melting, when your car's starter is overloaded), which is located somewhere between your battery and ignition switch. More than likely it is near the fuse panel of your car, but isn't mentioned in your owner's manual, because manufacturers don't consider it a part that owners are qualified to replace. If you don't have access to a shop manual, you are best advised to take the car to a qualified repair facility. It sounds like possibly either the ignition timing is off or the cam timing, causing starting problems, although it could be that you've gotten a poorly remanufactured starter motor. It is next to impossible to diagnose a car (especially the most complex part of the car: the electrical system) verbally. Suggestions and guesses are the best that can be done.

Over heating

you trouble shoot the problem by opening unit and force-powering fans to test for overheating during "being used loud for a few minutes". Read the fans' label for proper voltage to apply and proper polarity. I am guessing the fans will run on car battery voltage of 12 volts. Also, attempt to close up the unit to simulate real conditions. There should not be fuses for the fans. If unit is now cooling, then look for faulty thermistor, which turns the fan on during rising temperature. Once thermistor is located, a fast test is to "jumper" its two wires to simulate turn on.

Sony XM-DS1300 amp

If they have bridged the outputs of the amp, be sure that the "ohms" load is 8 ohms. This would then apply a 4 ohm load to each of the output channels. It sounds like they have bridged the output or else hooked up the speakers in a paralled configuration that is trying to kill your amp. If you are using dual voice coil speakers then you have to treat each of the voice coils as a seperate 4 ohm speaker and wire accordingly. You need to correct this NOW or else you will fry your amp. Good luck.
