MTX Audio TA92001 specifications Before Starting, Installation Mounting, Connections

Before Starting

MTX recommends that you have your new Thunder amplifiers installed by an authorized MTX retailer, preferably MECP certified. If you do decide to do it yourself, make sure you have read the instructions carefully and have the following tools:

•Electric drill

•Phillips bit or screwdriver

•1/8” bit

•Wire cutters/crimpers

•Safety glasses

•X-Acto knife

•VOM

Disconnect the vehicle’s negative battery connection. Any deviation from the recommended connection procedures may cause serious damage to the amplifier, speakers, and/or vehicle electrical system. Please double check the connections before turning the system on.

Installation

Mounting

Place your Thunder amplifier at the predetermined mounting location. Use a felt pen to mark the exact position of the mounting holes on the mounting surface. Set the amplifier aside. Then with a sharp, precise blade cut small circles in the carpet and padding around the four marks denoting your mounting holes to expose the metal underneath. Use a center punch to make an indentation in the metal to ensure that you drill the exact position for the screws.

Note: Please use common sense and make sure that all vehicle wires, gas lines, brake lines, etc. are clear and will not interfere with the installation. ALWAYS WEAR PROPER SAFETY GLASSES.

Connections

1. Bi-Level Inputs (Low/High Level Input) with Smart Engage™ –

Both a low and high level signal can be used. Be sure to lay the signal wire away from all power cables and vehicle computers. Use high quality twisted pair interconnect cables to decrease the possibility of radiated noise entering the system.

•Using RCA Connections: If the source unit has RCA outputs, simply attach a signal cable from source unit to the amp’s RCA input. This will provide signal to the amp.

•Using Speaker Level Connections: If the source unit does not have RCA outputs, a high level signal can be used instead by taking the supplied high level RCA adapter cables and connecting the bare wire ends to the vehicle’s rear speaker wiring. Connect the left negative speaker wire to the green with black stripe wire on the supplied high level RCA adapter. Connect the left positive speaker wire to the solid green wire. Do the same for the right speaker connection using the purple wire. Now plug the RCA connectors into the amp’s inputs.

2.Speaker Wire Connections – When installing the speaker wires, please take proper measures to protect them. For example, when connecting the door speakers, the speaker wire should run from the amplifier’s output terminals, under the carpet, and through the factory rubber boot (loom) that protects the wires in the inner door jam. If the factory boot cannot be used, take other measures to protect these wires. Sometimes the door has to be completely removed to use the factory boot. If this is something that you do not feel comfortable doing, please ask a professional to help you.

When connecting the speaker wires to the amplifier please observe the printed polarity markings on the amplifier’s StreetWires connector. Failing to wire the speakers in proper phase could result in a loss of bass response and/or poor overall sound quality.

These amps will have two PARALLEL speaker terminals, a positive and negative for a single woofer and OPTIONAL second set of positive and negative terminals for a two woofer configuration. These amps can drive a minimum of a 1 ohm load.

•Strapping Two Amps: Strapping two Thunder TA92001 amplifiers together has never been easier. When two Thunder TA92001 amplifiers are strapped, you can expect power output in excess of 8,000 watts and a total current draw of around 600 amps. Please see Power Terminals for suggested electrical system upgrades.

To successfully link the two amplifiers together you will have to follow the steps below carefully. The following information will explain how to configure each amplifier so one becomes the “positive” (Push) amplifier and the other becomes the “negative” (Pull) amplifier. Just follow the steps below and you will be on your way to massive amounts of power.
