  • In house head unit

    ok im sure somebody in here has done this before but im curious how to do this.
    since im scrapping my head unit and going true pc in car i have my old head unit just lying here and i was wondering the other day if there is a way to set up the head unit in my house/garage and use it as a receiver, i just cant figure out how i would power everything including the amps and stuff like that. if anyone knows how please let me know i think it would be kinda cool/
    thanks in advance.

    A PC power supply will go a long way there. Try

        depending on the amp draws you can get an ac-dc power adaptor from any electronic store

          I'm not so sure about amps, I don't have one and I won't be buying one for a while. Computer power supplies do come in rather heafty packages. Another thought is a power converter from an RV. They use those to provide 12v(ish) power to cars in car shows, like SEMA and such. They'll plug into a wall outlet and definately power all of your stuff. Don't know where to get one though.

              Not in my books, the draw from the amps would probably run the battery down quicker than the recharger. The idea sounds kinda crazy anyway.

              I've got a better idea. Go to your local pet store, and buy 30 hampsters. Build a big wheel for them to run around in. Get an alternator assembly and hook up the wheel. Insert hampsters and enjoy your music.

              I'm just messin with you. I think the RV power supply is the way to go, and I'd bet you can get one off ebay for a reasonable price.

                funny man but i bet if i asked if anyone wanted to get their *** kicked i bet u wouldnt be to funny then would u j/k

                i was looking for one of those but not much luck im still looking though.
                i just got off the phone with a guy from a car audio shop over here and he said that a battery with a charger would work fine?

                  Actually I'd be the first to crack a joke if *** kickings were being offered. I'm a smart *** with quick fists.

                  If the battery and charger work then go for it, it just sounds odd to me. Personally I wouldn't even try it.

                    i was a lil sceptical at first too but he said it would work and i dont see why not it should im not planning on running it forever just a lil at a time so i think i might go with that i just dont know if i wanna trust the battery acid possibly getting out.

                      I wouldn't worry about acid getting out, I'd think the drain would be too much for the battery to power for more than say 15 min, even with a charger.

                        Go with the battery and charger. I run that setup at home and it works fine. Obviously you can't run high power music for EXTENDED periods of time. But then again, I think you'd be having more problems with your neighbours if you were intending to pump that much energy out in a sessions. I run a JL Audio 500/1 and a 300/4 off a 570A CC battery with two 6A 12V chargers which was pretty cheap to set up at the time.

                        Basically this gives your ~ 144W continous power. Given that the RMS values are 1/root(2) x PEAK output of the amps (a situation which will rarely be achieved, and if so for only a short time) the power actually used by the amp is somewhat less than the stated value. Not to mention the overstated power output given by most amp companies these days - with JL maybe being an exception to that, but that's another topic.

                        Anyway the setup works a treat. Never had any power issues. Remember you can always charge the battery while not listening to music - or if you're finding you're running out of juice, add another battery and or charger.

                        I have seen (few and far between) some of those specialist 12V setups for use at car comps here is Oz. But the $$$ was quite excessive. In any case stick with the battery setup as it will act in a much similar way to a capacitor (in terms of supplying current in those ultra low impedance moments . You can always add chargers, transformers later.

                        Hope this helps,

                            If you are gonna run a bater with a charger it needs to be in a well ventilated area. Car batteries (lead-acid batteries) give off hydrogen when charging (and in lesser amounts when discharging). Hydrogen is explosive.

                            Modern batteries have catalytic converter jobbies to react it with oxygen in the air and produce water, but they are not 100% fool proof.

                              what size fuse dose the head unit have in it.if u can get a computer PSU with about the same value as the fuse then your fine. my friend dose it with his sub amp
