Hi,
I'm looking to add a subwoofer in my car but am not satisfied with a lot of the cheap garbage on the market when it comes to amps. Hence, I've decided to build my own 100-150 watt HIFI amp but have some questions on how to properly power it. Obviously, 12v from the car battery alone won't do the job since I need about 40v +/- to power the amp. So my thinking is (and tell me if I'm out of line) is to use a DC/DC booster such as these for example, but of course rated for what I need in amperage and voltage (and would be fused for safety). The other requirement for the amp to function as well obviously is dual DC power rails, and as far as I know, common DC boosters don't offer that. This is the main source of my roadblocks.
The amp wasn't original intended to be in a car and this is the suggested power supply:
Here you can see that after the voltage is rectified into DC, the two rail action happens (for lack of better word).
So what's the best way to get the power I need considering it would be in a car? Wouldn't some dual rail circuitry after the DC booster cut the voltage considerably? Like I said, I could be totally out of line! Any help would be great.
Thanks
