7.ThunderEQ (Variable) – This feature will add up to 18dB of low frequency impact to the audio system. The Bass Boost is centered at 40Hz.

8.Remote Subwoofer Level Control (Remote Gain) – This port allows the use of the optional “remote level control”. The Remote Subwoofer Control is a bass control module that can be installed in any location within the vehicle for remote adjustments.

9.StreetWires Connectors – All MTX ampliﬁers include StreetWires connectors for efﬁcient current and maximum voltage transfer.

10.Speaker Connection – Two sets of speaker terminals are provided for dual woofer applications. When connecting a single woofer, use only one set of speaker terminals.

11.Power Terminals – This is the main power connection for the ampliﬁer. The power and ground wire size should be the same gauge.

•GND – The ground wire from this connection must be attached to bare metal on the vehicle. The distance to the ground should be as short as possible and no more than 18”.

•REM – To turn the ampliﬁer on/off, this terminal must be connected to the source unit’s “remote or electric antenna” wire.

•+12V – The power wire from this connection must be attached to the positive side of the vehicle battery.

•CAP+ - Capacitor Positive Input – The ideal connection point for the positive side of the capacitor to increase the ampliﬁer’s performance.

CAP- - Capacitor Negative Input – The ideal connection point for the negative side of the capacitor to increase the ampliﬁer’s performance.•

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

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. 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.
