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 the 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 or poor overall sound quality. These amps will have two PARALLEL speaker terminals, a positive and negative for a single woofer and an 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 TA81001 amplifiers together has never been easier. When two Thunder TA81001 amplifiers are strapped, you can expect power output in excess of 3,000 watts and a maximum current draw of around 300 amps. Please see “Power Terminals” for suggested electrical system upgrades. Insert Table here to show 2 amps strapped, Power Output, Current Draw 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. 1) Label the first amplifier as the Positive amp. Then set the phase switch on this amp to the 0 degree setting. 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 2 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 volt ohm/multi meter. Please see “Adjusting the 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 ...
