  • Connecting the sound card to the speakers WITHOUT a headunit or amplifier

    Hello everyone,

    I aim to make my system as small as possible, so the existing head unit will be replaced with the carputer box. Does anyone have an idea as to how I can connect the sound card to the car's speakers WITHOUT using an auxillary amplifier? Is there any kind of electronic gizmo that does the job? I've read somewhere that I shouldn't connect the speakers directly to the sound card. Is that true?

    Any reply will be much appreciated.

    Kind regards,

    Samuel

    You could do it in theory, but you'd have very low volume and poor sound quality.
    You can get low-power rated amps for around US$100. In my eyes it would be worth the extra bucks for the sound quality.
    Have you looked in the FAQ yet?
    How about the Wiki?

      But my problem is that I don't have the space to mount an extra emplifier. Any other thoughts?

        That "electronic gizmo" you're talking about IS an amp. And if you get a cheap little amp, it'll certainly be no bigger than this mysterious gizmo would have to be.

          Sorry, I'm a newbie. I'm still learning the lingo. Could you perhaps provide me with some links to a retailer?

            when I was getting my system in my car, I hooked up carputer without AMP to see that work. The result was you could only hear if I put my ear right against speaker. I don't think that is not the way to drive.

            I have hatchback and did not want have AMP in trunk, so I placed under the seat. It works. I'm sure you got some space there.

                There are some small AMPs listed in this thread.
                I am sure you have some space.

                    You will definitely need a amp if you want to hear anything from your speakers. a 50 watt x 4 channel amp is not really all that big. They can usually fit under most car seats. If not there mounted in various other places such as behind rear seats, or on a wall in the trunk/boot/hatch.

                      That;s just a line level converter. Used to convert RCA's to speaker level voltage that an AMP might require. There's not enough current to drive your speakers though, which is why you want an amp.

                      Kenwood makes a small 40Wx2 amp that's only 7"x9".. These can easily fit under the dash, or the front seats.

                        simple, just use a wireless audio link. assuming you still have your car stero installed. plug this into your audio out and a usb port to power it, then tune it in on your car stereo. used it with my buddies mp3 player and the sound quality is great.

                          If you're not running an HU, get an amp. No way around it. You can get a generic amp off of ebay for $25

                          but I'd recommend spending a bit more and getting a quality amp. Theres tons of places you can hide it. Remember, you can put your carputer components practically anywhere in the car, and no two items really need to be next to each other.

                            you have to use either a head unit or an amp. Most head units contain amps (99% of them)
                            Bottom line, you have to amplify the sound output in order for it to be audible, unless you want to use your car speakers as headphones

                              I drive a Montero Sport XLS with the infinity sound system, which includes amps for all the speakers. I also have a 1400w amp powering a sub. My head unit has 4.5v pre-outs. What will the signal loss be from the carputer to the amp(s)? Should I get a pre-out amplifier? I have seen one that will take 4.5v from my head unit and change it to 9v but I canít find it on . Any help is appreciated!
                              Today I stuffed some dolls full of dead rats I put in the blender. I'm wondering if maybe, there really is something wrong with me.
