Setting up a car sterio system question

[eilif]

Hey I am setting up a car sterio system directly to a battery so that i can play music for parties that dont have outlets near by. It wont be on a car, but mounted on a wood box that i can haul around and plop down where ever i want some serious sound!

I got a new Pioneer DEH-1900 Mp3/wma cd player.

Its not even turning on.

Its got 3 wires (other than the speaker/remote wires) coming out that are the ground (Black), the +battery line (yellow) and an ACC wire (red).

On the wire diagram it says to plug the + (yellow) wire naturally into the plus of the battery, and the ground(black) to the chasis of your vehicle, in my case a wrench on the ground.  It says to plug the ACC into the ignition switch terminal.

Im pretty sure its not turning on because i dont have an ignition switch terminal to plug into, any way to bypass this?

No one at the sterio store mentioned the Acc wire, #$@$#@ers!

After i get this thing to turn on i have an Alpine 3555 amp to plug into it and a sub with some 6 by 9s. I got that wiring figured out, its just this dang cd player that isnt working!

Any Audio Gurus out there?

uh....what's a sterio?

[Speed55]

what kind of car?   The acc is when you turn the key back, so there should be a wire, or fuse panel you can tap into..  
Also, if you run a power line straight from the battery, try to fuse it before it goes into the firewall.

They usually sell car specific kits for newer cars

Place the yellow and red wires both onto the same power connection. Black to ground. The yellow wire is used to keep the presets in the memory. Be sure to use a fuse in the circuit.

[Chairboy]

The wire that usually connects to the chassis of your vehicle should NOT be plugged into a wrench that's stuck to the ground.

It attaches to the negative terminal on your battery.  The negative terminal is hooked to the chassis on the cars they describe.

usually a car stereo has a red (power when unit is on) black (ground negative terminal of the circuit) and a blue (constant low voltage to keep time / presets) this with is sometimes called the power antenna wire in older head units.


how you mentioned attaching the ground to the frame, that only works in a car where the battery itself is grounded to the same frame.


you also want a fuse between the power source and the unit. IIRC a 15amp fuse is the best to use but I could be wrong.

Please tell me you did not seriously ground the radio by attaching the ground wire to a wrench that is just laying on the ground.

#1. If you did, then thats why the radio didnt work. The ground wire goes to the negative terminal on the battery, not a wrench.

#2.  If you actually did, im sorry to say it but you dont have enough common sense to be messing with electricity or a car stereo, even if its just 12 volts

OMG your kidding me right? If you want a "portable" radio why don't you just go buy a boom box at Wal-Mart for the same price. Then you don't have to lug around a car battery.

but then he can't go boom-boom with those 6x9's and subs

Yep, the ground is at least the major problem here. Just a wrench on the  ground doesn't do it. You need to complete the circuit. Attach the ground to the negative terminal of your battery.

And A8balls is right...get a fuse in the circuit.

Take the radio, amp and 6x9s back to the store. Exchange them for your choice of "BoomBox" type radio and an inverter. Plug the radio into the inverter, and the inverter into your cars cigarette lighter/power point outlet and there ya go.

Much simpler and well ... in this case, considering the whole wrench thing, simpler is better.
