Car Amplifier Bracket

This is my model of a project I did for my 1999 Isuzu Rodeo car stereo amplifiers. I mounted it on the back of the rear passenger's seat which folds down. Here is a list of parts I used in this project. 3-Way 4 pin connector: https://www.amazon.com/gp/product/B01ACC13VA/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Extension 4 Pin Cables: https://www.amazon.com/gp/product/B016KSONJ4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Led Ribbon: https://www.amazon.com/gp/product/B00B2F3KDQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Power Supply: (You don't need this if you are planning to use it in your car, you can use your vehicles 12VDC power to provide power to the led ribbon(s) I had one laying around, so I used it for testing purposes as I built the light assemblies. https://www.amazon.com/gp/product/B01461MOGQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I use this VHB tape to secure the LED ribbons as the tape on the back does not hold up to change in temperature. Where I live, the temperature inside the vehicle can be as high as 120°F to -50°F. This tape keeps the adhesion with expansion and contraction. I have been using this stuff for years. https://www.amazon.com/gp/product/B0016HGFXW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Aluminum Z-Bar https://www.mcmaster.com/7062T13/ Kenwood Subwoofer Amp: https://www.crutchfield.com/p_113X5021/Kenwood-Excelon-X502-1.html Kenwood 4 Channel Amp: https://www.crutchfield.com/p_113X3024/Kenwood-Excelon-X302-4.html 1/2 Plywood for amp main base, but if I were to do it again, I would use 3/4" plywood or composite material because the 1/2" plywood flexed a little. 3/8" Aluminum for amp plates, they serve as a heat sink as well. I DA'd the aluminum surface to give it some shine. DA means you take a scotch brite pad and a random orbital sander and sand. Carpet is your choice, if you made the main base from something other than plywood it may not need carpet. maybe composite material, aluminum, or UHMW.
