Unpack and gently lay out the speakers and wiring on a table to familiarize yourself with the kit components and their layout.
The images below will vary from pin to pin.
Pictured are the subwoofer components covered in the "Cabinet Subwoofer" instructions menu. Proceed to the below for backbox instructions.
Pictured are the backbox components.
The existing backbox speakers may vary in terms of how the wires are connected. Pictured is Spike-2. The connector and wires leading to the speaker will be recycled with red (+ positive) and black (- negative) getting spade lugs added in the next step.
The red (+ positive) wire gets a red spade lug added. The black (- negative) wire gets a blue spade lug added.
Follow the image and notes to install the new backbox speakers.
Your backbox speakers are now installed. Test them to ensure they are working and sound good before proceeding to install the backbox amplifier.
Rest the amplifier module in a convenient location. (Note the "BBOX Amp" decal at the volume control - make sure you are using the correct amp.) Install the provided 3.5mm TRS Male Stereo Plug to 2-RCA Stereo Male Y-Adapter shown in the yellow circles.
Disconnect both factory speaker connections. The white circle shows the new speaker connection to the step-down module with the purple wire pair.
Cleanly connect the step down unit to the amplifier outs (the speaker lines that originally powered the factory speakers). These serve as the audio input to your PinWoofer Backbox Amplifier Module. Crimp connectors were provided with your kit.
Using the clear wires, connect your PinWoofer Backbox Amplifer to your new backbox speakers shown in the white circles. Your new amplifier will follow the factory configuration for mono or stereo. If left and right are swapped in a stereo configuration, simply swap the red and black RCA outputs of the step down unit or exchange left and right in the pin's menu settings.
Connect the 2.1x5.5mm power plug to the amplifier power jack as shown in the lower yellow circle.
At the PinWoofer 12V harness, insert the male T-Taps into the females, observing red to red and blue to blue as shown in the upper yellow circle. Shown is Spike-2. Other Power cables may be different in terms of the red/black power route. Please refer to the "12V POWER" Section of the website in the above menu to confirm your 12V pin specific power routing.
A close up of the 12V route taps, and the PinWoofer 12V power cable harness connecting to the power distribution board.
Your backbox amplifer is installed. Review all connections carefully.
Double check that your connections are correct. Adjust volume to suit and to match the relative level of the subwoofer.
Backbox audio out for SAM is located on the CPU / Sound Board for reference.
Pictured is the left speaker connection. In your new install the CAP can be omitted. Also, both the RED-YEL and RED series wire will be omitted. Each one of the two RED-WHT wires will be used as the negative [-] input to each of the two purple wire pairs, for each of left and right PinWoofer Amp Module Inputs in a later step.
Pictured is the right speaker connection from the factory. RED-BLK is a double wire pair that originates from J10 of the CPU / Sound Board. Each one of the two RED-BLK wires will be used as the negative [-] input to each of the two purple wire pairs, for each of left and right PinWoofer Amp Module Inputs in a later step.
Having disconnected the factory speaker wires from the speakers, install red speaker lugs to each of the two RED-BLK wires. Install blue speaker lugs to each of the two RED-WHT wires. These new lugs will mate with the existing male tap lugs on the purple wires. This completes the input connection to the PinWoofer Amp Module.
Using one of two clear output wire pairs, connect to the new right speaker as shown. SAM is mono so the choice of clear wire pair is arbitrary.
Using one of two clear output wire pairs, connect to the new left speaker as shown. SAM is mono so the choice of clear wire pair is arbitrary.
Connect 12V power and compare your wiring to the image.
