Car Audio Receiver

spray2000 · May 17, 2016

Ok, So I'm going to do something different I don't know if anyone has ever tried this before, But i'm going to try to run a converter 12 dc (Link at bottom) to a car and hook up a home theater type receiver to that converter running from the battery in the car 300 watt's and my speakers run at only 150 watt on the receiver. I'm running a 10 inch sub kicker that's 500 watt rms and two 60 watt and three 100 watt speakers kenwood. Do you think that this could actually work with a converter and be able to run all that power through just a cigarette lighter?

You'll kill your converter and battery within a week, or you'll kill your car with fiery death.

Plus, I really don't think the internal cables will support the amount of current they'd have to give to the converter, if the battery can give that much juice at all.

In my opinion, since this is a big risk project, I suggest you either *read* a lot around the subject of changing the 12V line and how to properly install an amplifier in your car. I am *pretty* sure they use dedicated lines for it, instead of hooking it to the 12V of your lighter.

Cheers!

First even that device says to use the battery clips (not the lighter port) when using devices over 150 watts, which most receivers will most likely be. Doing a quick search on standard cheap Pioneer reciever it was rated 210 watt consumption.

You will burn up your cigarette light port at a minimum trying to do this. You need to add dedicated wiring to the inverter if you really want to do this.

Also remember this DC to AC conversion is not going to be a pure sine wave type which is generally not good for electronics, which also causes other problems. You're better off just getting a DC car amp.

This is an exceedingly bad idea.

First off any converter is not going to deliver the clean current needed for a home amp to run properly.

Secondly, you can get better performance in a smaller size using car audio equipment

Third, you are planning to use 4 ohm car speakers on a home amp which generally puts out 8 ohms. So you will either be halving the power to each speaker, or you will need to bridge the channels on the amp just to power each speaker properly (and therefore have half as many channels). And many home receivers will not support this.

Fourth, even if you do all that the first time you turn it up it will likely clip out, even with a fuse in there you could still manage to burn up the car's wiring (and the minimal amperage to the cigarette lighter will not help)

There is a reason they sell car audio equipment, and home audio equipment. Don't do this.

1. Pull out the cigarette lighter. See those 2 little wires? That is what will be trying to power this thing.
2. Look at the fuse for the cig lighter. What amp rating is it? Probably 20?
3. How will a home receiver cope with the big temperature swings you find in a car?
