STRAPPING THUNDER AMPLIFIERS
Strapping amplifi ers brings two mono-block amps together and unleashes the power of both into a single
channel confi guration. Think of it like a bridged 2-channel amp which takes a left channel and a right channel
and combines them into one output. Strapping is essentially the same process. One of the mono-block amps
serves as “one channel” and the other mono-block amp as the “second channel.” The primary difference is
that the two mono-block amps are not in the same heatsink like the channels of a 2-channel amp.
Strapping requires that the two mono-block amps function as one, so they must be setup to work together.
Both amps need to receive the same exact signal, same exact level of signal, same exact voltage, etc... Just
follow this guide to build the Biggest, Baddest, Boldest system...ever.
It has never been easier to strap two MTX Thunder TA92001s, or even two Thunder TA81001s, together to get
maximum power from these super amplifi ers. When strapped, expect power output to exceed 6,000 watts
RMS for two TA92001 amps with a current draw around 600 amps. Or, for two TA81001 amps, over 3,000 watts
of RMS power with a current draw of around 300 amps (Table 1).
ELECTRICAL SYSTEM UPGRADES
When strapping Thunder Amplifi ers, it is important to remember that to get the desired power from them,
you need to supply them with the power they require. You must upgrade the stock battery and add additional
batteries to the system. We recommend a minimum of three batteries with a cold cranking amp (CCA) rating
of 725 or more. Please remember to install a minimum of 1/0 AWG StreetWires power and ground cable for
each alternator. Two 200 amp or greater alternators are strongly recommend for this system because these
amplifi ers are capable of pulling more than 600 amps. After your bank of minimum three batteries, you will
need to run 1/0 wire to each amplifi er. Just adding extra batteries will not solve the need for power. It will
actually put more of a load on the alternator, in turn yielding less power to the audio system.
MTX Audio recommends West Co. SVR80 or SVR100 because they are a sealed battery that can be mounted
in any confi guration and supply the power needed, and high-output alternators from either Ohio Generator or
PowerMaster.
STRAPPING TWO TA92001 AMPLIFIERS
To successfully strap two TA92001 amplifi ers, follow the process outlined here carefully. It details how to
confi gure each amp so one becomes the “positive” (Push) amplifi er and the other becomes the “negative”
(Pull) amplifi er.
1. Connect the amplifi ers’ power, ground, and remote but do not supply the 12 volts from the batteries to the
amplifi ers until later in the process.
2. Label the fi rst amplifi er as the Positive amp. Set the phase switch on this amp to 0˚. Label the second
amplifi er as the Negative amp and set the phase switch on this amp to 180˚ (Figure 1).
3. Using a “Y” adapter, split the “Left” side of the RCA output from the source to the “Left” RCA input
receptacles on each amp. Using another “Y” adapter, split the “Right” side of the RCA output from the
source to the “Right” RCA input receptacles on each amp (Figure 1).
Note: Only the positive speaker terminals on each amplifi er will be used.
4. Connect the positive side of the speaker wire to the “positive” speaker terminal of the amplifi er labeled
Positive. Connect the negative side of the speaker wire to the “positive” speaker terminal of the amp
labeled Negative (Figure 2).
Note: The voice coils on the JackHammer must be paralleled (Figure 2). Be sure that the impedance of
the subwoofer is no lower than a 2 ohm load to avoid possible damage to the amplifi er.
