MTX Thunder 6500D Car Audio Amplifier - Answered Questions & Fixed issues

Check the ground wire and the power wire for a bad connection.

Hi Smith,
Are you sure this is a transistor or a diode? What is a part no printed in this part?

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.

there are coils inside the amp the power it an ur output input could be burned out . u can bring it to a pro to fix it . it would cost no more then $100 to fix it . i hope this was helpfull

make a dark

Sounds like you have your cables backwards. You must have positive connected to negative somewhere. Take a good look at the connections.

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.

Hi, It sounds like your amps thermal shutoff is tripping since when the amp is upside down it can't cool as well as right side up. If you absolutely must mount it the way you have, I would recommend getting yourself a small fan, like a computer fan and mount it to blow on amp when system is on. They draw very little power, so you can just wire to your car's switched power source...but be careful to wire it to amps ground due to noise that can sometimes happen when you ground things at different locations around vehicle. Google "amp fans" or "computer fans" and you should find a good spot to get one. Make sure you get a 12v unit. Let me know if this helps! THanks

Sorry to say mate but that is one blown up amp! :(

My solution to this would be to get another amp

Sorry Matey

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.

It is too old for online manuals. Any colour light would show it has power and usually a red, green or blue LED. Red is sometimes reserved as a fault condition in conjunction with another power light. https://www.google.com/search?q=mtx+810d+amplifier+manual https://www.google.com/search?q=mtx+810d+amplifier ..

MTX will know that one. https://www.google.com/search?q=make+my+MTX+TERMINATOR+AMP+1+OHM+STABLE ..

Is a 2ch and 210watts peak power

What amp r u using

yes a higher voltage rating is OK lower voltage rating is not good.

If you have to ask, take it to a repair shop.

power to-battery plus ground;; remote''

THE GREEN LIGHT SHOULD SHOW WHEN AMP IS POWER UP AN RED WHEN IN PROTECTION MODE
