Any dc voltage at amp output is a sign this is blown. the problem is on the output transistors and can only be fixed by a technician

Take this apart and look at the magnet wire windings look for any thing broke or burnt. If not it is very likely it is more cost effective to buy new.

SOURCE: MTX 502 2 chanel amp Pre amp problem?

Unless your amp is 1 (one) ohm stable then you may have fried it. When you attach a 2 ohm load across a bridged amp then you have effectivly placed each output channel on a 1 ohm load. Not a good thing in most cases. Try hooking up ONE speaker on one channel and one input to that one channel one at a time. Then switch the speaker/input to the other channel and see if you can get either or both channels to work independently. Needless to say you must turn the amp off before you make ANY change in the wiring.

SOURCE: No power output

Set the meter to AC volts and measure the AC voltage on the RCA cables where they plug into the amplifier. The black meter leat will go on the shield ground of the RCA cable. The red lead on the center conductor. You may have to turn the volume up to get a reading on the meter. At high volume, you should read at least one volt but the actual voltage will vary due to the audio signal. If you get no voltage on the RCAs, measure the AC voltage on the input to the LOC. Let me know what you find.

Any sub's I hook my mtx jackhammer jh1200 up to instantly are forced down and eventually fry. Why is my amp doing this?


This problem is caused by one or more of your output devices (FET, Transistor, or IC) is shorted and causing the power rail to be connect through your speaker. Your amp boosts the 12v supply to a much higher +/- voltage rail which powers the amp's outputs. When the amp is shorted or overheated to a point of destruction you can end up with this problem.

It will need to be repaired by a technician.

My mtx thunder 6500d amp hums when connected light turns on but no output


Make sure you have a proper ground wire connection. The ground wire should be connected solidly to the vehicle chassis in a paint-free location. If it is loose or there is paint t the connection site, you will have problems with the amp output. Also check the speaker wires to see if they are touching the vehicle chassis. This will cause a short circuit and you will not have output from the amp. Finally, check the leads from the head unit. They should be RCA cables, and should have a good connection to the amp.

MTX Lolita Sub amp defective power transformer (open primary) What's the transformer voltage?


Without Knowing the Output Chip or transistor Numbers, I don't know but Most 100 Watt anps use 60 to 70 Volt Centertap Sacondarys. Also if You Take the Cover off The Transformer you will find a Thermal Fuse in the Primary. I have bypassed the Thermal Fuse and went with a external fuse, Go for it.

Can you run two mtx 6500d amps in parallel for more power?


Not suggested to parallel the output of two amps. Instead take each amp, find out what the amps lowest impedance it can drive is and select your speakers based on that. According to MTX these are stable down to 2 ohms without a rated output power of 500Watts X 1. If you get two dual voice coil subwoofers with each coils characteristic impedance of 4 ohms, when you parallel the two coils you will get a 2 ohm load. Just maek sure the speaker can handle the 500 watts.

I have a mtx thunder 81000d amp i need to know if i can bridge it


Hello frank_sadach,

"Bridging" connects 2 amp channels to one output. The MTX 81000d is a single channel amp so it cannot be bridged.

Hope this helps.

I have a mtx 421d. can I over heat if I connect only one channel.


Hello jaimemm_77,

The MTX 421d is a mono amp. It only has one output channel.

If you are asking about hooking up only one channel to the input, then no, the amp will not overheat. But the output will be significantly reduced. It would be best to use a "Y" adapter with a single female and two male connectors to split the channel into both inputs.

Hope this helps.

Mtx 1501D


if your power light is on then check your preamps (sub out from head-unit).Maybe you need to turn on that output thru head unit's audio menu.Also when using dual voice coils if you wire them out of phase there will be no output
