Alright, so here is the thing, I am going to be building a car amplifier for a friend, there are a few things I need to know first, I kind of looked around but could not find good enough information, The things I am needing to know is; materials and guides on how to do this, I am in no hurry to get this done, and I am not sure if money is an issue, he is buying all the materials and I am doing all the work, meaning all the soldering, wiring, building it, and setting it all up, I will be needing guides and a list of materials that will get me to be able to build from a decent or awesome amp, I will be talking to him on what car it is and any other specs I need to know about this, If anyone here knows anything about this or can find some guides or materials and can post here that would be awesome, would love to get as much information as possible thanks
