20 Most Recent MTX Terminator TN400/4 Car Audio Amplifier Questions & Answers

its just a power light to let you know its on

You may have touching speaker leads going into the amp. Make sure the tinsel is not touching across the speaker inputs on the amp. Also check your ground. It should be solidly connected to the vehicle chassis in a paint-free location. Finally, make sure there are no exposed speaker wires touching the vehicle chassis.

The red light is a power protection circuit designed to shut the amplifier down due to an overload or wiring problem. If the amp was playing then shut off, my guess is a problem with the speakers or the speaker wiring. Some amplifiers are only stable to a certain load. For example, most car audio speakers are 4 ohms which is the resistance placed upon your amplifier to produce a certain volume of sound. If you bridge two 4 ohm speakers together in parallel, you cut the resistance in half, thus increasing the amount of power (and volume) to your speakers. This also creates more heat and could, in effect, shut your amplifier down. I would find out how the speakers are wired to determine the resistance of the load your amplifier is pushing.

check the ground make sure its not loose from the frame of your car thats why the red light comes on.

low Ohm speaker configuration or bad current intake. how many speakers you have on it? what size of power cables you use?

your mounting depth will be 4.3" to 5.5"

that means that your amp is in protection mode, check all your wires and also the speaker configuration.

if its not coming on it usually means you have a bad ground if it works for a little while then does it then its over heating and you will need to get a fan

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 ..

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''
