    heya guys i got a project to instal an 5.1 surround into my company van,
    it almost has 8 track so no support for any kind of mp3,

    i dont want to alter the van itself so it has to be installed in sutch a way that it can be removed by picking it up and walking away,

    now i got this 5.1 that i got laying around and i whant that in my van to connect to my Phone,

    it has an 12v 185 watt converter output built in so i can draw power from that, it has to be cheap and working this weekend if possible,

    the 5.1 is powered from 230v to 13.5-0-13.5 whit 2.4 amps per pair,
    tryed powering it from a 12 volt battery but it seems (as i feared) to use the 27 volt to power controlls of sorts

    i have ferrite torroid coils at hand so any circuit that runs of 12 volts whit an ne555 and a coil whould be most usefull,
    ofcours it has to be a center tab aswel to have the 14-0-14 it whants

    any feedback or input whould help alot, i could figgure this out alone but ideas of what whould work or personal input on a project whent wrong is Always appreciated

    U need a DC to DC converter as used in car amps. It coverts 12V to ± Bus DC voltage that an amp would require
    Building a DC to DC converter for car use is very tricky and needs experience in this kind of circuits.

    Use a 12VDC to 220VAC inverter and power your amp.

    A basic two transistor self resonant push pull power oscillator may do what you need.

    Simple and minimal component count plus easy to use any of your toroid cores as a the base for making a transformer.

    Why cant ppl be happy with the stock audio the cars come with from factory which is almost always better than any custom installs anyways.

    And 5.1 surround ? BLAHSPEMY!! Such thing have no buissness beeing in a car, in fact 5.1 surround is **** in all regards!

    2.0 stereo is where its at, and nothing else.

    5.1 Sound is better t0o if you know how to build them.
    With active crossovers and quality amps it's a blast

    Well i've never ever heard any 5.1 that sounds better than 2.0.

    For me its 2.0 all the way, i HATE surround sound, its not natural for me.

    Well. I made one. As soon as I was using it, someone wanted it.

    It's best when you are watching Dolby surround movie
