Give it a ride though the dishwasher, the amp may just be dirty.

Im sure you have but check all the fuses and be sure ground/power is in the right spot, and check remote wire for cuts

Ya. Just hook one sub to your amp (bridged) and hook the other sub (positive and negative) to the first subs positive and negative

the fans might not be running and if the fans are running then you need to keep the amp cool by letting it have access to the a/c or air from the windows. think of it like if you keep your body in a box for a long period of time and there is no air circulating then your body heats up same thing an amp need air circulating to stay cool.

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.

You need to check your woofers. Most likely one or both may be a) blown or at a dead short or b) the ohm rating on them may be too low. What model woofers and amp do you have??

If there is a zero ohm connection across the B+ and ground terminals, it should blow the fuse as soon as you apply power.

 

 

 

A large capacitor between your battery and the amp may help. Your alternator is most likely strained by the amp's power consumption. If you can't get a stronger alternator or suitable capacitor, you may nbeed to replace your battery and alternator more often than normal.

the fuse may not be working, you could try a larger sized one, also if you have the old power cable try it again with a larger fuse in place, if it worked before its likely to just be the fuse wasnt big enough, check all the other connections are in the right place, if they all are and you know the amp hase worked before then it could only realy be the fuse isnt big enough or the power lead is faulty.


cheers, adam

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 ..

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