It's been a while since I've been researching about how to power up a car stereo without a 12 volt battery that I will surely have to recharge later. Why?
well....because I have a sony mp3 cd usb aux ipod-cable unit, 4x52w watts w/sub-out, what else could you ask for? I know, a nice set of speakers, right? I'm lucky to say that these speakers will be based on one set of sony 4 ohms 4 way drivers, another set of Boston acoustics 4 ohms 3 way, and one Miller&Kreisel; 8" sub. Besides the custom speakers building, I will perform the foam repair job to the sub and to one pair of Boston drivers, i'm working on a tight budget so... here we go.
Step 1: Stuff you need
The second step is to gather the tools and items needed just to begin, it is not necessary to have everything at hand when you work on a project in the way I do, I only spent some of my free time, and I buy the things I need, this way I stay busy for a long. Yet there is nothing wrong with doing your project in one weekend but it can be frustrating and stressfull. Besides the fact that, when I start to do something I don't know exactly the way it will end, but the big idea is there, so I knew that my unit would ended mounted on a computer tower with a pair of "preview" speakers. So to start the tower, speakers and the atx power source are required the same as the drivers and stereo.
