MTX TC2002 amplifier has a noisy gain control

My MTX TC2002 makes a scratching sound when the gain control is adjusted. Is there a way to clean or replace it? Thank you.

With the system turned off, try turning the gain back and forth full range several times. This will often clear any dust off the resistor surface and is the freebie solution. Obviously you need to put the gain setting back where it was. There is also electrical contact cleaner you can buy in spray cans if you feel like opening up the amp. Most likely the gain potentiometer is sealed though and will not take the cleaner. Only other diy solution is to replace the gain pot which involves soldering.

Not really, other than sending it to MTX or an authorized repair shop.

Amp and sub have been working great together then all of a sudden the amp is not putting out enough power to push the sub. MTX Thunder 311D


check to see if one of the RCA cables is unplugged or bad. check the gain check the sub level control on the deck if yours has one.

No sound from speakers, but there is power to amp


make sure the power wire and the remote wire have voltage. at least 12 volts. make sure the ground wire is good and has a good solid ground. after that make sure the rca cables are getting signal from the radio. if you have a small speaker or tweeter you can touch the wires from the speaker to the rca cables and it should play music very quietly. meter the subs and make sure theyre ok and not shorted or bad. if all that checks out good.... the amp is probably bad. start with all the simple stuff and work youre way up. if the amp has good power and signal and good speakers then the only thing thats left is the amp. good luck

Does the woofer move in and out in relation to the movement of the gain control?

The 1501 is very similar to the 81000 but there are important differences. The 1501 is a better amp.

If you turn the gain up and down, does the woofer move in and out in direct relation to the rotation of the gain?

What do you mean by "you only feel current going through subs"?

Well it could be that your ears just got used to the bass. It happend to me after about a week of haveing my subs. And make sure that your power wire hasnt got melted somewhere. also that you have good ground.

Short Curcit?


the amp have an input harness? those can go bad, or maybe line level inputs are loose. If its not just a loose connection on one of the amps inputs (speaker, line, or power) leading to the circuit board( which could easily be soldered back to the corcuit board), than your looking at an integrated circuit problem- not easy to fix.

Tuning the amp


St the crossover to LP (low-pass), and around 80Hz for 12" subs or 120Hz for 10" subs. Turn the gain all the way DOWN. Turn the radio about 3/4 or 4/5 the way up. Adjust gain until subs start to sound a wee bit sloppy and then adjust back 1/8 of a turn. Also, DON'T turn the LOUD function on or the BASS all the way up on the radio.... these should really be flat as possible.

Amp turns off when head unit is playing cds


Connect the remote turn on to the blue wire w/white stripe coming from the head unit, NOT the solid blue wire which is the antenna turn on.
