channel conﬁguration. 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 ampliﬁers. 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 Ampliﬁers, 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 ampliﬁers 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 ampliﬁer. 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 conﬁguration and supply the power needed, and high-output alternators from either Ohio Generator or PowerMaster.

STRAPPING TWO TA92001 AMPLIFIERS

To successfully strap two TA92001 ampliﬁers, follow the process outlined here carefully. It details how to conﬁgure each amp so one becomes the “positive” (Push) ampliﬁer and the other becomes the “negative” (Pull) ampliﬁer.

1.Connect the ampliﬁers’ power, ground, and remote but do not supply the 12 volts from the batteries to the ampliﬁers until later in the process.

2.Label the ﬁrst ampliﬁer as the Positive amp. Set the phase switch on this amp to 0˚. Label the second ampliﬁer 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 ampliﬁer will be used.

4.Connect the positive side of the speaker wire to the “positive” speaker terminal of the ampliﬁer 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 ampliﬁer.

JackHammer specifications

The MTX Audio JackHammer is a powerhouse in the world of subwoofers, known for its sheer size, impressive performance, and engineering excellence. Developed for those who demand deep, thunderous bass, the JackHammer has carved a niche for itself among audiophiles and car audio enthusiasts alike.

One of the most striking features of the JackHammer is its massive 18-inch diameter. This size isn’t merely for show; it enables the subwoofer to move a significant amount of air, which is crucial for producing the deep bass that many listeners crave. The JackHammer is designed to handle high power levels, boasting an impressive RMS power handling capability, which ensures that it can deliver the loud bass without distortion even at high volumes.

Another standout characteristic of the JackHammer is its innovative design. The subwoofer features a high-temperature voice coil, which allows it to handle substantial power without overheating, thereby increasing the system's durability and reliability. The subwoofer also utilizes a dual voice coil configuration, allowing for flexibility in wiring and impedance that can be adapted to suit various system setups.

MTX Audio has equipped the JackHammer with advanced materials to enhance its performance. The cone is constructed from durable materials that resist flexing and distortion, ensuring that the sound produced is clean and precise. The heavy-duty rubber surround plays a vital role in maintaining the integrity of bass production, allowing for greater excursion and improved sound quality.

Additionally, the JackHammer is engineered for optimal efficiency with its specially designed magnet structure. The powerful magnet increases sensitivity and overall output, enabling it to produce maximum sound even with lower power input. This feature is particularly useful for those looking to integrate the subwoofer into different audio setups without compromising on sound quality.

For those who are serious about their car audio experience, the MTX Audio JackHammer stands out as an emblem of raw power and performance.
