    output transistors are ok
    these transistors are the driver transistors that preceed the output stage .
    from the place where the audio is fed from the preamp circutry through this transistor array to drive the output transistors .

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.

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.

About 6 months ago i had installed the mtx thunder 6500d amp to run my 2 rockford fosgate power T1 12inch subs and every thing was great untill recently it stop puting out sound it still powers up and...


good morning and welcome to fixya. not a bad setup you have here at all, you ned to start by checking the speaker wires inside the box to the connector inside and then the wires from connector to amp on outside. if everything looks fine there, then you need to check the amp for power out of the rca plugs to make sure the channel is not dead. if you are looking for a new amp you can try several different ones from fosgates new line up to soundstream's. im running 4 polk momo 12's on the tarantula amp and love it. they are great amps. hifonics also has a new line up pretty cool stuff, heard really good things about there stuff to. good luck and let me know so i can help you out.
