Question about Car Audio & Video
HELLO THESE AMPS ARE FAMOUS FOR DRAWING ALOT OF CURRENT AND IF YOU PLAY THE AMP WHILE THE VOLTAGE DROPS FOR TOO LONG YOU CAN FRY THE AMP BUT AS FAR AS THE SECOND AMP NOT WORKING AS WELL YOU MAY HAVE A PROBLEM WITH THE RCA'S OR THE OUTPUT ON YOUR HEAD UNIT WENT BAD OR YOU HAVE A BAD GROUND CHECK ALL FUSES THEN CHECK THE GROUND WIRE TO MAKE SURE ALL PAINT HAS BEEN SCRATCHED OFF AND THAT IT IS CONTACTING BARE METAL THE ONLY OTHER OPTION IS FIND A FRIEND THAT HAS THEIR WIRES RAN AND HOOK UP YOUR AMP ON THEIR SUB IF IT WORKS THEN TRY IT WITH YOUR SUB IF IT GOES INTO PROTECT THEN YOU MAY HAVE A BLOWN SUB CAUSING THE SHORT HOPE THIS HELPS THERE ARE ALOT OF OPTIONS START WITH THE WITH GROUND AND GO FROM THERE

Hi Saint108. You're describing it well, and i know what the problem is already. The MA audio amp, can't hold with a 2 ohm load. It's too low for that amp, that's for sure. Those are budget amps and they are not well built enough to handle low ohm setups like that. It's overheating and there's no ways around it.. Other than wiring your subs differently ! Just wire your sub directly (not in parallel) in a 4 ohm load, you will notice it will stop overheating that much. Do it quick, you'll most likely fry your amp giving it such hard work !! The HUM you're hearing could be related to it also. Try that, and keep me posted on the status. Thanks ! Cheebster.

This indicates a possibility of a power supply issue, you may have to open up the unit and take voltage measurements to determine if the voltages are correct. In order to do this you will need a schematic diagram of the unit. Once you have the schematic you will be abor to tell which voltages are legitimate. I hope this helps

SOURCE: low ohm light wont go off
pbabin is correct, that would cause resistance to be at or near 0 ohms and the amp would pull a lot of current (if it did not go into protection mode).

This is a multi-tiered question. First of all, you're going to want to run the subs at a 2ohm load (if the amp is capable) to get the maximum power from it. Use the 5.0.1 for the subs only, that's what it's designed for. Run the cap in conjunction with only the sub amp as it has the largest power requirement. You can not link the two amps to increase output as they are first of all different amps and second of all not designed to run that way. Some amps are but they must be identical.
Set the crossover on the sub amp probably no higher than 80Hz (I like it lower than that but that's a personal preference) and turn the sub-sonic filter off.
Now, one of the most important things about a subwoofer is it's encosure. If it's a properly built box designed for your subs specifically then you should be ok. You dont' specify if it's ported or sealed etc. That would be helpful to know as well as it's approximate size (air volume).
The head unit can also have some bearing on how things sound, as I recall the Sony X-Plod units are fairly decent for the price and if set up properly should sound ok.
If you need further assistance please provide a little more info about the sub enclosure etc.

Let's measure some voltages. If you have a DMM measure the DC voltage at your amps power supply input. If much less than 10 volts I would suspect you may have possibly damage your power wire. When you have a lot of current flowing through a wire the resistance will change and cause a larger voltage to drop across that wire. Having to low of an input voltage is a trigger mode for some amplifiers to go into protection. Let me know what you find and we can go from there.
