  2. Take a general overview of the MTX Terminator TNA252 Car Amplifier.
    • Take a general overview of the MTX Terminator TNA252 Car Amplifier.

    • The first thing we notice are all the power and speaker terminals on the right side, then the RCA Line In/Out’s on the left.

    • There is also the EBC Port, Gain, X-over with variable frequency control, and High Level Input (HLI) on the left side of the amp.

    • The internal parts of this Amplifier consist of:

    • Main Circuit Board

    • Transistors

    • Resistors

    • Diodes

    • Capacitors

    • Other components that help amplify, filter, and enhance the sound.

    • CAUTION: Be careful not to spill liquid onto this circuit-board!

    • In this step, I’ll explain how this MTX Terminator TNA252 Car Amplifier works.

    • This amplifier requires an 8 gauge power wire that is connected directly to the battery with a fuse and a ground wire that is connected to the chassis of the vehicle.

    • The amplifier is activated by the remote turn-on wire that is connected to the stereo.

    • The stereo sends audio signals to the RCA input on the amplifier.

    • The audio signals then get filtered and amplified by the internal components of the amplifier.

    • These components include: capacitors, transistors, resistors, X-overs, etc.

    • The amplified audio signals are then sent to the speakers, to put out sound!

    • To put back together the MTX Terminator TNA251 Car Amplifier, simply screw in all internal screws (silver screws) using the #2 Phillips Screwdriver.

    • Then, screw in the sides (black hexagon shaped screws) using the Allen Wrench.

    • Finally, place the back cover of the MTX Terminator TNA251 Car Amplifier on top of the sides, and screw the 6 black Phillips screws in using the Phillips Screwdriver.

    • Congratulations - you’ve finished the teardown of the MTX Terminator TNA251 Car Amplifier! Time to shove this amplifier in the back of your car and blast that music!

    All you did was take apart and put back together. What did you fix ?

Lame write up. All you did is remove the cover and tell what a amplifier does. Not how it works. This was a waste of time article!
