I am having a problem with my MTX TC6001 amplifier. Here is what happen, I was driving around listening to my music a little loud but not as loud to a point where it would destroy my amplifier. The next thing I know, is that my bass just cut off. Now at first I thought it was my MP3 player because I use it so much that the headphones jack is worn out so if you move the connection then sound loses all highs and lows, and sounds mono.

Well, this was not the case. So, then I checked to see if my amplifier was hot and turned off because of that. In fact my amp is cool. I took a look at the fuses and they were both blown. Thinking that this would be my only problem, I checked the wires to see if there was a short then I replaced the fuses (yes, with the right fuses 30A X2).

I go to turn on my stereo thinking I would be able to listen to my music again. I was way off on that. Yes, my amp turns on. But not the way I wanted it to.

I hear a pop that sounded like a turn on thump (something I never heard on this amp) but still no bass. I walk to the back of the car and noticed that my speakers have moved outward. You know when you are trying to find the polarity a speaker terminal and you test it with a battery to see if the speaker moves inward of outward. Well, that is what it looked like. Thinking that this would damage my subs, I quickly turn off my system.

When I got back home, I changed the subs with a cheaper set to see if they would do the same thing. Yep they did. So, I remove the RCA cables thinking that this is the problem, nope wrong again. So, I grab my DDM and checked that voltage at the terminals and it read 12.44 volts. So, then I checked the speaker terminals because they have to produce power well, they gave a reading of a constant 26 amps (yes, I removed the speaker wires). This is with and without no signal (the RCA cables were removed for the without part)

I tried many things to fix the problem. Here is the list.

1. I replaced the fuses
2. Checked the voltage (12.44 volts)
3. Checked the wires
4. Checked the RCA cables
5. Changed the MTX TC6001 amp with a MTX TC4004 amp to see if the power cables were bad and that MTX TC4004 worked on the same wires that the TC6001 was on.

6. Changed the TC6001 with the TC4004 amp to see if the RCA cables were causing the problem The TC4004 amp worked just fine.

7. Changed the speaker wires.

My two TC4004 show a zero amps at the speaker terminals with no signal so I am sure that there shouldn't be an ampere at the speaker terminals when there is no signal.

So, can anyone help me with out telling my to go to a shop and get the amp fixed. Because the last thing I want to do is replace the MTX TC6001 because I would also have to replace both of MTX TC4004s because they no longer sell TC amps. It does matter that all my amps look alike. I did not even get my money worth I only have the amps install for 4 months now and they are no longer under warranty because I had them for over a year. Hey, a college student has to save up his money to get something nice.
