MTX Audio TA92001 guide

1)Label the ﬁrst ampliﬁer as the Positive amp. Then set the phase switch on this amp to the 0 degree setting. Now label the second ampliﬁer as the Negative and set the phase switch on that ampliﬁer to the 180 degree setting.

2)The interconnects coming from the source unit need to be split into each of these two ampliﬁers. Using a “Y” connector, split the “Left” side of the interconnect from the source so that it can go into the “Left” RCA input receptacles on each ampliﬁer. Using another “Y” connector, split the “Right” side of the interconnect into the “Right” RCA input receptacles on the ampliﬁers in the same way.

3)Only the positive speaker terminals on each ampliﬁer will be used as the connection points for the speaker. Connect the positive side of the speaker wire to the positive terminal of the ampliﬁer labeled Positive. Connect the negative side of the speaker wire to the positive terminal of the ampliﬁer labeled Negative. Make sure that the impedance of the subwoofer is no lower than a 4 ohm load. This is important in order to avoid possible damage to the ampliﬁer.

Running two ampliﬁers strapped will require “gain matching.” This will require source material that includes test tones and a volt ohm/multi meter. Please see “Adjusting Individual Gain Controls”

Note: Please pay attention and make sure the speakers or woofers are the correct IMPEDANCE (OHMS) BEFORE attaching to the ampliﬁer.

3.Power Terminals – Please take proper measures during installation to protect the power wires as best you can. For example, when running the power cable from the vehicle’s battery through the ﬁrewall, use a ﬁrewall bushing for protection. Run the power wire through the interior of the vehicle, under the carpet, and to the ampliﬁer. If this is something that you do not feel comfortable doing, please ask a professional to help you. Be sure to lay the power wire away from all signal cables.

When connecting the power wires to the ampliﬁer please observe the printed markings on the ampliﬁer’s StreetWires power connector. Failing to wire the power cables properly could result in ampliﬁer damage.

•+12V: This is the main power input for the ampliﬁer and must be connected directly to the positive terminal of the car battery for the ampliﬁer to operate properly. It is important that a main fuse is installed a maximum of 18” from the battery.

•GND: This is the ground connection for the ampliﬁer and must be connected directly to the metal chassis

of the vehicle for the ampliﬁer to operate properly. A properly grounded ampliﬁer can be run harder and longer than a poorly grounded ampliﬁer. The ground on the ampliﬁer should be as short as possible and be connected directly to the vehicle’s metal chassis. Do not connect to factory bolts of ANY kind. When attaching the ground to the chassis, sand all the paint away from the contact point. A grounding block like the StreetWires GT0 should be used whenever possible as this piece of equipment has 5 times the surface area of a normal screw.

The gauge of the power and ground wire is often an overlooked aspect of ampliﬁer installation. The more power the ampliﬁer receives, the more power it will produce. Power cables have a natural resistance, and will lose voltage by the time the power makes its way to the ampliﬁer. The larger gauge (diameter) wire will hold more voltage over longer runs. Also, by having a larger diameter ground wire, the ampliﬁer can run more efﬁciently. MTX recommends using a minimum of 1/0 gauge power and ground cables to get the best performance.

•REM: This connection turns the ampliﬁer on and off and needs to be connected to a remote turn-on wire from your source unit if you are using a low level input connection.

Note: When numerous ampliﬁers are used in the same system, look into using a relay with a separate power wire connected to an alternative power source to take the strain off the source unit. Normal source units can only keep a constant 12 volts to 2 or possibly 3 amps. This wire should also be run away from the RCA cables.

•CAP+: This 4 gauge terminal is internally wired in parallel with the +12V on the StreetWires Power connector. It is the ideal connection point for the positive side of a capacitor to increase the ampliﬁer’s performance.

•CAP-: This 4 gauge terminal is internally wired in parallel with the GND on the StreetWires Power connector. It is the ideal connection point for the negative side of the capacitor to increase the ampliﬁer’s performance.
