CAR HIFI SYSTEM without A CAR :)

Mr.Amokk · 25th June 2009

What's up?

I wanna build something like a real nasty, portable ghettoblaster. I got:

- A subwoofer-roll
- two speakers
- an amplifier
- a USB/CD/radio.

Everything from my old car system. I wanna put those things together to one BIG; roll-able piece of blasting-noise-bringer

Got it?
I will have to go to the hardware-shop, to get me some wood and stuff.

My biggest problem is the power-issue. Do you think a regular car-battery will do the math? How am I supposed to recharge it?

Does anyone have some ideas/advices? Did somebody allready build something like that in the past?

Help apreciated!
Peace

Just get a transformer, or a car-battery charger. You'll be good to go!

Oh yeah. I build something like this for in my boat. With a car battery. Problem is, as long as you're running just a car stereo it will play for hours, but when adding additional amplifiers (for subs for instance) the battery will be dead in 2 hours. I would recommend the transformer anyway. Cause you know that the battery always will be emtpy just when you need to use it!

And.. not to be an asshole, but one of the reasons a car sounds so different is the closed environment. So i would install it in a vocal booth or something, to duplicate the small "room".

Saw one for like 22 Euros on eBay, but I gotta plug it into a ruglar electric socket in order to charge it. I wanna go to a 3-day festival. There won't be any sockets :(

You know, construction workers in Holland often have those kind of self-made radio's. Or boomboxes. Without the Sub, i think you can get some decent time out of your battery. Also depends on the battery of course. (How many Ampere)

But three days... don't know. Take multiple batteries?

For three days you could use a car battery and hook it to your car with jumper cables and charge it with the car's alternator whenever it dies. Otherwise you'll need a generator for that length of time. Or a crapload of batteries.

I own a 12 volt audio store.
We power our main display board with a 12 volt power supply running to a deep cycle marine battery.
Powers 17 display radios,2 video monitors,2 capacitors and 2 sub amps without breaking a sweat.

You'll drain a car battery pretty quick if that is the route you choose to take.
A deep cycle marine battery will work much better but before it goes dead make sure it gets a full charge otherwise they don't last too long.
