Thunder 801D Car Audio Amplifier service manual

Mtx 801

Do you have the remote power hooked up on the amp? Have you checked the fuses? or maybe the audio wires are bad.

Above, is how to troubleshoot, protection problems.

if theres a switch on ur amp that says LPF Full or HPF put it on LPF for low pass frequencies

you might need to turn the amp down and get some better wires to carry the load. when at lot of juice is being tranfered you need good wires to hold it

I am guessing the bass control is just a potentiometer that you plug in. It could be open and that is why the bass dies. As far as the switch goes, I am not familiar with the amp but it sounds like a crossover between low frequency and subsonic frequency.

Hello chacha_loves,

Usually having to "wiggle" the equipment for it to work means there is a loose connection either on the external terminals or where the terminals are soldered to a circuit board. For it to power on OK, but not produce output seems to indicate the speaker connections or output transistor connections.

Check the external terminals and make sure that there's no "play" when you gently wiggle the attached wire. If it gives slightly, the solder connection inside may be defective. If no components are damaged, you can usually restore complete function simply by reheating the bad or loose solder connection. Use a low wattage soldering iron with a well-tinned tip or a controlled temperature soldering station. Don't overheat the connection and don't add more solder.

If there's still no output, it's probably a defective component.

Hope this helps.

there are already holes in the firewall, which exsisting cables run thru to the back of the dashboard, the holes have rubber grommet fillers in them, put ur cable thru one of these exsisting ones...
hope this was helpfull

no you will not blow it out by hooking up both voice coils. But First before you do, what oms are they. and is your amp one oms stable? There a lot of ways you can wire double voice coil. But if you can get me that info i can send you some digrams to help you out and tell you whats best.

ASSUMING that the amp is OK with a 2ohm load then you "set it up" by the configuration of the speakers you use. Two 4 ohm speakers if parallel will give you a 2 ohm load. However, if you are bridging the ouputs then a single 4 ohm speaker bridged between the two outputs will put a 2 ohm load on each channel. Be very careful if you are bridging the outputs that you know what you are doing. On average, when bridged wrong (too much load) the amp will last about one month before it fries. Get some help if you are bridging. Be sure not sorry.
