Aux only DIY Car stereo

Hi I bought an old car recently. But came with bad stereo head and perfectly working speakers. Now I figured out that all I need in my stereo in aux input which I can connect to my mobile device. Is there any way to make an aux input port without using any radio head, ie, the direct connections with AUX. also please explain wiring layout of head.

Turn laptop speakers into aux speakers

My laptop just died and I took it apart. The speakers have a 4-pin connector, which I would like to splice into aux and power to make an aux enabled speaker I can use. How do I do this? Pics: Thanks and RIP laptop. A little eulogy, because why not: Dear laptop, you will be missed. I had you for 5 years and you were a great machine. I took you apart and put you back together. We had a great time together and you lived a long life. I hope you have a great afterlife as a set of speakers, external monitor, hand warmer, and many more projects. You will be missed.

Stereo Stolen!

My car stereo was recently stolen.. Bummer. Here is my idea; I am tired of putting stereos in my car only to have them stolen. I don't want to buy another CD player w/ an aux in input for my mp3 player, since I don't really play cd's anyways. What I want to do is install just an aux input line to my car speakers and mount that easily in the empty hole. Is that possible? Do you somehow need to power the speakers? How do you go about doing that w/out buying a new stereo? My main goal is 1)to put something there that will run the sound from the MP3 player 2)not need a stereo to do it. 3)do this so no one would think it is something they could steal and profit from. HELP! :)

adding aux line in directly to boombox ampli

Hi guys i am Ramanta from Indonesia i have an old boombox, Sony CFS-1110s (similar mechanism with CFS-1100s) what i want to do is add an aux input to them. I have seen a lot of instrucrables about it, but nothing about this model. I find a similar unit here the aux in is conected directly to the IC Amps pin. I have the IC diagram, what i dont understand is this model have a dual IC8207k. One for each channel. TA8207K is a stereo IC, so how do i do the wiring? For single IC its just INPUT1-INPUT2-GND. In dual setting they have 4 input and 2 ground. I dont want to use any tape adapter since its sound terrible here i attach the complete diagram and schematic in PDF please give some tutorial, im a beginner in this kind of thing) hehe my email sorry for the bad english :D

How can I connect my old stereo speakers to a computer/iPod? Answered

I own an old Panasonic "CD Stereo System SA PM-21". I got it a few years ago, so it is not the newest, and unfortunately I can only listen to CDs, cassettes, or the radio. The speakers are really good however, so I'm not ready to simply give the whole stereo away. So my question is, how can I connect a computer or iPod to these speakers? They have two pairs of cables each as you can see below. Somebody already suggested using an FM transmitter or cassette tape adapter, but those options would probably give me much less quality than I would get if I connected directly. Would I need some sort of amplifier or converter? Is it possible? Thanks in advance for any help.

My Prius is still cruising along fine. But, I tire of messing around with FM transmitters to get my audio into the radio/audio system.

No thanks.]I see all the newer cars with an AUX audio input jack. I'd like to put in such and/or a Bluetooth input.I went to a local car audio store and they said $450 to add it in.

Anyone got any insights on this for a DIY car bluetooth system?

I found this:;=282112739276#ht_10252wt_1397 It looks like it would meet all the requirements I need - It has AUX in for non bluetooth devices, bluetooth for phone calls and streaming, A microphone, Media controls and even an amp and should be able to be wired in to the cars' 12v power output. I am concerned that I am overlooking something obvious... I know that the the media controls might only work over bluetooth and not over AUX...but thats not too much of an issue is suppose...Does anyone have any more information on it?

Need advice for adding aux-in/line-in to Philips AE2160/00-A AM/MW/LW portable radio

Hey there, this is my first post! :) I'm from Germany, so please excuse my grammar! :D The reason why I'm opening up this new topic is, I didn't find any instructable or guide on how to add an aux-in/line-in to my simple mono AM/MW/LW radio Philips AE2160/00-A. There's not much to find out about the technical specifications besides the standard product information: Tuner • Analogue tuning • Wave ranges FM 87.5 - 108 MHz MW 525 - 1606.5 kHz /04 LW 150 -255 kHz /00c FM/MW /04 FM/MW/LW /05 FM/MW/LW • Ferroceptor for MW (and LW) • Telescopic aerial for FM (and SW) Amplifier • Max. output power 300 mW RMS • Tone control Music /News Sound system • Loud speaker 100 mm • Metal grill Power supply • External supply /00c, /04 230V /05 240V AC • Batteries 2 x 1.5V , type R20/D cell/UM1 Connections • Headphone socket 3.5mm General • Material Polystyrene, metal grill • Weight (g) 520 • Dimensions (mm) 210 W x 150H Here's a link to a photo of the device:;=2000&$jpglarge$ I didn't even find schematics/circuit diagrams for this or a similar device. There are lots of tutorials on how to add such an input to a car radio or a boombox/stereo cassette player a.s.o., but not for a simple AM/MW/LW radio. My questions are: 1.) Are there any similar hack projects here in the step-by-step or forum section? 2.) How do I find the right connector or place to solder a 2-way-switch between the sections (tuner, amp, speaker)? After the hacking job, it should be possible to switch between normal radio listening mode and aux-in/line-in mode from an external mp3 player, notebook, a.s.o.. 3.) Is there anything else to know for this project? Yesterday I've opened up the case for the first time and looked over the circuit board and the connections. I had no cam to take pictures, but I try to take some mobile phone cam pictures of the circuitry and parts at the next opportunity! Cheers, arok1

Any tips or suggestions are welcomed.

I have a record player with a broken cassette deck, I want to add an aux port. Answered

I have an older Prolectrix record player with CD and cassette. The amp itself seems to incorporate the cd and radio. The cassette seems to cut into the amplifier circuit when one is inserted into the deck via a micro switch.   I have managed to remove the cassette module with all it's wiring, it was plugged straight into the board via a header plug. I was considering using a module such as this, as it would fit in the existing hole quite nicely. I haven't tested voltages as yet. 3.5mm is fine, or stereo phono is also usable. I need some advice as to which wires I can use as an input. Obviously there are two power wires to the motor. The microswitch has 3 wires, red, black and yellow, then you have the three more going to the play head. Any ideas please? My electronics knowledge is quite basic. Here's a picture of the turntable in case you know it.

What is the best route to adding a USB power source to a guitar amplifier?

My girlfriend has a Fishman Loudbox Mini amp which has a 3.5mm auxiliary input on the back. She bought a cheapo bluetooth audio receiver that is powered by USB and outputs through its own 3.5mm jack. It works great but it takes up two wall outlets, and drastically reduces the distance it can be from the wall due to a short audio cable. So I need an easier power source for the USB dongle. I had imagined a coupler that would sit between the amp and its power cable. I could frankenstein a USB-wall-outlet connector into this coupler to provide a USB power source close to the aux input. However it may be easier to find a 5V source inside the amp and just add a usb port. I'm not sure, which is why I'm creating this post.
