I found some guide to being able to add a sub woofer in my trunk without needing to buy a new HU, keep in mind im nearly broke. But there are some pictures id like to show of some spliced in my trunk aswell as my stereo which run to my trunk.
Please reply if you know what the wires the wires that are spliced into do or anything that will help me out! thanks!
There four are at the back of my HU
